Flush roof rails are also common. The Flush roof rails fit perfectly on the roof. The advantage is that the height of the luggage rack is lower than that of the raised side rails. The models that use this kind of vertical rail are Audi Q7, BMW X1, Jeep Guide, Subaru Outback and other models.

T-slot roof rail The T-slot roof rail is not popular, Such a longitudinal rail does not affect the overall appearance of the vehicle when the roof rack is not installed, and it is convenient if the roof rack needs to be installed, and the height of the roof rack is lower than the above two types of roof rails. The models that use the T-slot vertical rail are Land Rover Discovery 3, Porsche Cayenne, Haval H3 and other models.

No roof rail Most cars don't have vertical rails when they leave the factory, Some car manufacturers take into account the needs of the owners. In the design of the vehicle, the interface of the luggage rack is reserved. This can also be convenient. Retro luggage rack

It is relatively simple to install the roof rack on the Raised side rack. It is only necessary to measure the distance between the front and the rear in order to prepare the bicycle rack or the trunk for later installation and then fix the roof rack on the vertical rail according to the manual. It is. Here to remind everyone that some brands of roof racks do not have anti-theft measures, which requires the owner to pay attention to the location of the parking, try to choose in a guarded parking lot or garage, not only to prevent the loss of the roof rack, but also Prevent items in the vehicle from being lost or the vehicle itself from being hurt.

The owner needs to pay attention to some things when installing and using the roof rack.

1. After installing the roof rack, the screws should be checked regularly. The inspection interval is determined according to different road conditions and load conditions. Generally, it is best to check once a week.

2. The goods should be tied tightly or fixed on the roof rack. All the goods should be placed evenly and the center of gravity should be reduced as much as possible.

3. If you want to tie the baggage with a rope, it is best to use a rope that is not flexible.

4. When the items on the roof rack are large, be careful to drive, and pay special attention when braking.

The roof rack cannot be overloaded

The roof rack should be installed with a lock cylinder. Pay attention to the lock and remove the key during use.

The aluminum alloy material roof rack will not rust, but will slowly oxidize during use. The acidic and alkaline substances in the rain will have some erosion with the surface. This is normal.

Scratches during the loading process are normal

Ensure that the roof rack seal is mounted on the crossbar during installation to prevent noise and windage

Do not disassemble the roof rack frequently after installation. For ordinary cars, frequent disassembly roof rack will damage the paint. For vehicles with reserved fixed points, frequent disassembly roof rack will damage the screws in the fixed position, so although the roof rack is detachable, Be prepared for long-term installation

Why is the market price so different? It is mainly caused by the disparity in the materials used in the products.       

First, there are two materials, aluminum alloy, and high-strength plastic, at the main support. Among them, the aluminum alloy material has the advantages of high strength and lightweight, so it is used most widely, but the trace elements contained in the aluminum alloy are different, and the strength and hardness of the manufactured material are also different;       

High-strength plastic materials are more prone to aging because plastics are prone to thermal expansion and contraction, and assembly precision is relatively poor. Now some well-known brands generally use the aluminum alloy, manganese steel, and other materials, which not only enhances strength, hardness and anti-aging. Level.       

After the roof rack is installed, the rationality of its mechanical structure is judged from whether it is easy to deform or not. It depends on the thickness of the material used to see if the joint is tightly connected. After the roof rack is installed, it is judged whether it is easy to deform or not. The rationality of the mechanical structure.      

 How to identify the material of the roof rack?       

The material is the core of quality. We can identify it by simple observation to see if the surface gloss is consistent, whether it is uniform, whether there are bumps and cracks; depending on the thickness of the material, see if the joint is tightly connected.

This one can fit many models of car, and the roof rack wind noise is very small

Check the bottom of the cylinder, if it is open, then can be opened to take apart the cylinder, replace the seal, and then installed on it. If it is dead, it is only the top of the welding position cut

Because of the different manufacturers, their location is different, the vast majority of the design of the fuel hole in the hydraulic cylinder. See the photo:

Pallet is a horizontal platform device for loading, stacking, handling and transporting cargo and articles as unit loads. General use of wood, metal, fiberboard production, ease of handling, handling unit materials and small quantities of materials. The main types of trays are wood, plastic, metal and other materials, wood is now the most widely used, because of its cheap, strong; plastic tray more expensive point, load is also small, but with the plastic tray manufacturing process, Some heavy-duty plastic pallets have emerged and are slowly replacing wooden pallets. Metal tray strong and durable, the disadvantage is easy to corrosion, the price is higher. In the computer, the tray often refers to a small piece of the lower right corner of the program, that is, "notification area", play a notice \ reminder \ notes \ warnings and so on, so that users can make the appropriate shortcuts. Plastic pallet is the use of the most advanced patented technology, the production of plastic-wood materials, assembled by the various specifications, size tray, pad. It combines the advantages of wooden pallets and plastic pallets and steel pallets and basically abandon its shortcomings, the price is lower than other types of pallets; products with high strength, good toughness, deformation, not moisture absorption, no mildew, Corrosion, anti-aging, easy processing, low-cost, recyclable, non-polluting and so on.

invented by the American Mark · Savannah In 1960. At first just want to design a new three-dimensional wallpaper. One day, when he flew out of the window to see the clouds, feeling like a cloud is used to protect the aircraft safe landing, inspired by this, he created a plastic bubble film. As a result of shock, moisture, anti-wear properties, bubble film will soon become popular packaging materials. Later, because many people like to pinch bubble on the bubble, so bubble film has been given to alleviate the psychological pressure function. Today, Seal Air, the patent holder of the bubble film, has more than 17,000 employees in 52 countries and regions, earning more than $ 4 billion in revenue each year from bubble film.

1 Tensile tension is the tensile strength of the film after the elastic elongation. Longitudinal stretching increases, ultimately thinning the film, shortening the width. While longitudinal stretching is beneficial, excessive stretching is often undesirable. As this will thin the film, tearing, and at the same time increasing the tension applied to the package. In this case,

2 Allowable stretches Allowable stretch refers to the maximum tensile strength that can be applied to maintain the necessary properties for a given application. Allowable stretch varies depending on the application. The larger the allowable stretch, the less the amount of film to use and the lower the packaging cost.

3 Adhesion between the self-adhesive films after the contact, in the process of winding and wrapping, the packaging products can be tightened without loosening. Self-adhesive by a variety of external factors. Such as humidity, dust and contaminants. There are two main methods for obtaining self-adhesive films. First, the processing of smooth surface with a glossy film; Second, the use of additives to increase the adhesion of the film surface wetting effect, thereby enhancing the adhesion. In this case,

4 Ductile toughness is the anti-puncture and tear resistance of the comprehensive nature of the film. The tear resistance refers only to the degree of tear resistance of the film after it has been tensioned and pierced. The risk of tearing must be horizontal, ie perpendicular to the direction of machine operation, since tearing in this direction will loosen the package, and the package will remain secure even if it is torn longitudinally. In this case,

Formulation of pallet wrap/stretch film One is to add PIB in the polymer or masterbatch, the other is blending VLDPE. PIB for the translucent viscous liquid, the direct need to add special equipment or equipment to transform, are generally used PIB masterbatch. PIB out of a process, generally three days, also affected by temperature, high temperature, high viscosity; low temperature is not too sticky, greatly reduced by the viscosity after stretching.

With the increase of the number of carbon atoms in the copolymer, the branch length and the degree of crystallinity decreased, and the "twist or kink" effect of the copolymer increases, so the elongation and puncture strength and tear strength also increase. And MPE is a highly stereoregular polymer, molecular weight distribution is very narrow, you can accurately control the physical properties of polymers, so there is further improvement in performance; and because MPE molecular weight distribution narrow, narrow processing range, processing conditions difficult to control, 5% LDPE was added to lower the melt viscosity and increase the flatness of the film. Material density also affects the properties of the film.

1, should be based on different environments, use a different working oil. When the ambient temperature at -5 ~ +45 'C, please use the synthetic mirror oil, the oil must be added to clean, so as not to affect the normal work of the hydraulic system.

2, should be checked before use ministries structure is normal, the connection parts are loose phenomenon.

3, the goods should be spread on the fork surface, not about the tilt or single fork hoisting to prevent damage to the parts or goods overturned after the accident.

4, after the end of the operation, the goods should be unloaded, and the car into a low position, not for a long time will be heavy pressure on the fork.

5, the pallet jack in the transport process, may be due to inverted reasons, the hydraulic system into the air, resulting in slow or pressure from the piston rod up to work requirements. Should be no load conditions, the pallet jack placed in the low-release position, while pulling the grapple, back and forth several times to return to normal.

The large cylinder 9 and the large piston 8 constitute a lift cylinder. Lever handle 1, small cylinder 2, small piston 3, one-way valve 4 and 7 form a manual hydraulic pump. Such as lift the handle so that the small piston to move up the small piston lower end of the oil chamber volume increases, the formation of local vacuum, then check valve 4 open, through the suction pipe 5 from the oil tank 12 oil; forced down the handle, the small piston down, The pressure of the lower piston chamber is raised, the check valve 4 is closed, the check valve 7 is opened, and the oil of the lower chamber is input into the lower chamber of the lift cylinder 9 through the pipe 6, forcing the large piston 8 to move upwards. When the handle sucks oil again, the check valve 7 closes automatically, so that the oil can not flow back, thus ensuring that the weight does not fall on its own. Constantly pull back and forth handle, you can continue to push the oil into the lifting cylinder under the cavity, so that heavy objects gradually rise. If the shut-off valve 11 is opened and the fluid in the lower chamber of the lift cylinder passes through the pipe 10 and the shut-off valve 11 flows back to the tank, the weight is moved downward. This is the hydraulic principle of a pallet truck.

Simply it is just like the Inflator,but take place air with oil

Maintenance of the pallet jack will extend the service life , maintenance inspection includes oil, lubrication air excluded.

It is best to check the oil level every six months at the handling station. New oil into the rubber container to be below the surface height of 5 mm, add oil when the goods must be in the lowest position. To replace the seal, the air may enter the hydraulic system, place the joystick in the lowest position, and then swing the handle a dozen times. Lubricate the movable part with motor oil or lubricating oil. Also pay attention to the daily inspection and maintenance, inspection of the pallet jacks can be as much as possible to reduce wear and tear, need special attention to the wheels, axles, forks, lifting and lowering control. Whenever the work is completed, the forks should be empty and lowered to the lowest position.

(1) Do not overload;

(2) Ground conditions are allowed to use;

(3) Loading goods Properly

(4) Wear safety shoes and gloves during operation

(5) Operation check before each use

(6) Do not ignore potential hazards that may be present during operation

pallet wrap membrane rupture of the phenomenon of many, especially for the relatively low tensile thickness of the membrane is more common, and transverse rupture in the production process is most common, high-speed transverse stretch film is the most likely to rupture, we Generally, transverse rupture is divided into three types, longitudinal rupture, and rupture, and the following are the reasons for the analysis of three types of transverse rupture. There are many reasons for transverse rupture of membranes, the specific can be divided into:

1, the raw materials contain large differences in performance of impurities (such as low molecular weight oil, etc.); 2, the castings have significant horizontal stripes, bubbles; 3, a variety of obvious transverse pull before the rupture factor to further expand (longitudinal thickness 5, the filter damage, high-quality film castings impurity 6, the head leakage of material 7, roller crush; 8, the surface pressure is too large; 4, Scrap, equipment, scratch the film; 9, extrusion, longitudinal stretching temperature is set improper; 10, the top of the oven and the air duct on the accumulation of volatile substances fall on the film

Viscosity control of pallet wrap

Pallet Wrap good adhesion to the outside of the packaging film layer and layer of sticky together to make goods strong, sticky access to important ways there are two: one PIB is added in the polymer or its masterbatch; the other is blending VLDPE. PIB for the translucent thin liquid, indirect increase in the need for special equipment,Or to stop the reform of equipment, are generally adopted PIB masterbatch. PIB out of a process, as usual to three days, the other is also affected by temperature, High temperature, high viscosity; low temperature is not too sticky, greatly reduced by the viscosity after stretching. But also to the best film products stored in a certain temperature scale,(Recommended storage temperature at 15 ℃ ~ 25 ℃). Mixing VLDPE, slightly less viscous, but no special requirements for equipment, viscosity is absolutely solid, not subject to,Time control, but also affected by temperature, the temperature is higher than 30 ℃ when the absolute viscosity, less than 15 ℃ when the viscosity is slightly worse, by conditioning the LLDPE adhesive layer,In order to achieve the desired viscosity. Three-tier co-extrusion to adopt such methods.

Physical and mechanical control

High stretchability of the stretch film contributes to the identification of goods; high longitudinal elongation is conducive to pre-stretching, and save the cost of data; stretch film good The puncturing function and the transverse tear strength allow the film to meet sharp edges or edges of the product at high draw ratios without breaking; the high compliance point enables the post-packaging More tight goods. Cast film production of high transparency, do not focus on the debate here. With the increase of the number of carbon atoms in the copolymer, the length of the branched chain increases, Crystallinity is low, natural copolymer "winding or kink" effect of growth, so elongation progress, puncture strength and tear strength are also improved. While M PE is a highly stereoregular polymer, molecular weight dispersion is very narrow, able to accurately control the physical properties of polymers, so there are further functional But also because MPE molecular weight dispersion narrow, processing scale is also narrow, processing conditions difficult to control, daily increase of 5% of LDPE, to reduce the melt viscosity Degrees, increasing the flatness of the film.

According to the packaging equipment , the machine pallet wrap can be divided into "pre-stretch" and "resistance to stretching"

1, The resistance of stretch-type machine: refers to the resistance by stretching the resistance of the resistance mechanism, the stretch film pulled out when the passive slower than the speed of the pallet cargo rotation, and then pull the film was wrapped around the same time to Above the cargo. Because the resistance can be adjusted to "zero", any quality of the pallet wrap film or ordinary plastic film can be used, but for lighter, higher goods, can not achieve stable packaging, and high film consumption.

2.Pre-stretch-type machine: refers to the pre-stretched film frame mechanism, the pallet wrap film in accordance with the pre-set "stretch ratio" stretch after wrapped around the tray of goods. Its advantages are uniform film, beautiful packaging, adaptability (ultra-light, ultra-high goods can be used), and under the same conditions than the "resistance to stretch" type of saving supplies 30 to 50%. The machine should be packaged in bulk, should be configured the machine, high efficiency, uniform appearance, packaging, good quality, and speed.

Scope of application:

Glass fiber, non-woven fabrics, carbon black, chemical products, electronic products boxes, ceramic products, mechanical and electrical equipment,

1.Can reduce packaging costs

Packaging the same volume of goods,Pallet wrap compares with shrink film the amount can be reduced by 1/3

2.Compare with ordinary packaging film, to finish bundled packaging work. Can be exempted from a lot of accessories (such as packing tape, tried to play rope, cardboard angle, the buckle, etc.). And can simplify the packaging equipment, saving a lot of power energy.

3. A pallet wrap can tighten the goods as a whole, the decline in the process of storage and transportation of goods damaged, collapsed, scattered package phenomenon. One ton of pallet goods. After wrapping around. A maximum tilting angle of up to 45 degrees

4. The goods can be waterproof and dust-proof by wrapping around. Transparency is still high. Easy to distinguish the varieties of packaged goods. the pallet wrap is not toxic, there is no taste. Can meet the requirements of food hygiene function.

1,The manual packaging

The packaging is the most complex of the pallet wrap packaging, the film mounted on a shelf or by hand, by the pallet migration or membrane around the tray. This packaging speed is slow, just for pallet wrap film thickness of 15 ~20 um.

2.Machine pallet wrap film packaging

This is one of the most widespread and most common mechanical packaging methods, by the back rotation or membrane around the back rotation, the film can be fixed to the bracket can move up and down. This packaging is fast, about 15 to 18 per hour. the suitable film thickness is about 15 to 25 μm

Viscous manipulation, excellent viscosity of the goods outside the packaging layer and the layer of sticky together to make the goods strong, excellent stretch film equipment used 7042 material produced by the stretch film itself has a certain viscosity, based on the viscosity of different needs , There are two main ways to increase the viscosity: one is to increase the polymer in the PIB or its masterbatch; the other is blending VLDPE

Stretch film application of a wide range, mainly in cooperation with the use of the tray, sporadic products for the entire set of packaging, instead of small containers. Because it can reduce the cost of bulk goods transport packaging more than 30%, it is widely used in metal, mineral, chemical, pharmaceutical, food, machinery and other goods on the whole set of packaging;

1, Stretching

Stretching is the ability of a film to stretch elastically after tension. Longitudinal stretching increases, eventually thinning the film, shortening the width. While longitudinal stretching is beneficial, excessive stretching is often undesirable. As this will thin the film, tearing, and at the same time increasing the tension applied to the package

2, Toughness

Toughness is the combined nature of the film's puncture and tear resistance. The tear resistance refers only to the degree of tear resistance of the film after it has been tensioned and punctured. The risk of tearing must be horizontal, ie perpendicular to the direction of machine operation, since tearing in this direction will loosen the package, and the package will remain secure even if it is torn longitudinally.

3, Stress retention

Stress retention refers to the extent to which the tension exerted on the film can be maintained during the stretch wrapping process..

4 Stretch to allow

Permissible stretching refers to the maximum stretch that can be applied to maintain the necessary properties for a given application. Allowable stretch varies depending on the application. The larger the allowable stretch, the less the amount of film to use and the lower the packaging cost.

5, self-adhesive

The adhesion after contact between the films, during and after the wrapping, enables the packaged product to be tightened without loosening. Self-adhesive change depends on a variety of external factors

1. Stretch packaging saves raw materials compare with shrink packaging and do not require the machine, energy saving.

2. High strength, elastic tension, for any geometric shape of the goods avoid injury to goods .

2. Elastic recovery, refers to the stretch film in a certain proportion of stretching, to maintain this state for some time, after the release to restore the size of the ratio of the original size. If its ratio is relatively small, indicating that its elastic recovery is better so that it is better on the stretch, not easily deformed.

3. Permanent deformation refers to stretch the stretch film to a certain ratio, the length of the growth and the ratio of the original length. If the length of growth is relatively large, indicating that its elastic recovery is relatively poor, easy to deformation.

4. Pull to maintain, when the stretch film stretch a certain percentage, to maintain this state for a certain time, the ratio of tensile force and F force value is the tension to maintain, F force is the stretch film stretch at a predetermined maximum elongation Force, through the tension to maintain this indicator, you can see the stretch film tensile strength.

5. Anti-piercing, through the process of piercing the rupture of the film when the force value and the displacement through the time that can reflect the stretch film puncture resistance, high-quality stretch film should have good puncture resistance, So as to ensure the safety of packaging.

6, light transmittance, haze, stretch film in the use of the time required to have a higher degree of transparency can be detected by light transmittance and haze.

Hand stretched film is more prominent feature of the operation can be anytime, anywhere, do not need to move to a specific location, occupying an area is relatively small, for the production of small customers. For hand stretch film requirements thickness 15mic-20mic, the minimum thickness of 0.007mm, width requirements in the range of 5cm-45CM, and the tensile rate of 200% -400%, compared to the machine stretch stretch film, hand With stretch stretch film stretch rate is smaller, probably because the force exerted by the machine than the human large%, in performance and size to meet the requirements of machine to ensure good packaging.

1.The use of casting production, the tensile stretch film is very high transparency, and, elongation is also increased, puncture strength and tear resistance is also greatly enhanced, so the stretch film is more durable, more secure packaging.

2.The density of the material also has an effect on the properties of the stretch film. If the density is increased, the orientation is high, the flatness is good, the elongation in the longitudinal direction is high, and the yield strength is high, but its transverse tear strength and puncture strength The decline, we should pay attention to the amount of non-sticky layer of LDPE added to ensure the overall performance of the stability.

3.The addition of the LDPE material reduces the coefficient of friction of the non-adhesive layer and controls the stickiness of the stretched film, thus avoiding adhesion of the packaging film to the product or pallet.

2.The control of the physical and mechanical properties of stretch film mainly for its high elongation, high yield point, and high transparency requirements, so stretch film can maintain a good stretch, more tightly packed and conducive to Product identification, packaging quality and appearance are good.

assemble the pallet jack

The Packaging Tape material is BOPP (Biaxially Oriented Polypropylene) film and glue,Is widely used by enterprise, company, personal life

method for producing a packaging tape

Packaging tape is make a rough surface in the BOPP film with high-voltage corona, Then cover surface with the glue, Divided into small volumes, that is our daily use of tape. Adhesive tape glue is acrylic adhesive glue, also known as pressure-sensitive adhesive, the main ingredient is tincture grease

Classification of packaging tapes

Transparent packaging tape, colorful packaging tape, printing packaging tape

The history of packaging tape

In May 30, 1928 apply in the United Kingdom and the United States ,Drew developed a very light, pressure-fit adhesive, the first attempt is not enough sticky,So Drew was told: "Take this stuff back to your Scottish bosses and ask them to put some extra glue,During the Great Depression, people found hundreds of uses for the tape, from tinkering cloth to protecting broken eggs.

Check before use

If Pallet Jack are not used for a long time, the hydraulic system may inhale air, which can be excluded as follows

Push the knob to the lowered position, shake the handle 4-6 times, and then release the control knob . If necessary, you can repeat the process several times until it works

Maintenance

Routine daily inspection, remove the exception in time, do not use the car in failure to extend the service life. the fault should be asked to remove by professional worker, and if you want to replace pallet jack parts, the parts should be provided by the manufacturer. Each rotating joint should plus motor oil every three months , pay special attention to the wheels and shafts do not be entangled with debris, keep all the wheels turn light to meet the safety requirements
