The correct use of pallets should make the goods packaged in combination codes on pallets and properly bundled and wrapped so as to facilitate mechanical loading and unloading and transportation, so as to meet the requirements of loading and unloading, transportation and storage.
I。 Load Quality of Pallets
广东11选5The weight of each pallet shall be less than or equal to 2 tons. In order to ensure safety in transit, the weight of the goods should not exceed two-thirds of the width of the pallet.
2。 The Placing Method of Pallet Goods
According to the type of the goods, the quality of the goods on the pallet and the size of the pallet, the way of placing the goods on the pallet is reasonably determined。 The utilization ratio of the bearing surface area of pallets should generally not be less than 80%。 For pallet goods, the following requirements are required:
1. Hard cuboid goods such as wood, paper and metal containers are packed in single or multiple layers of interlaced codes, stretched or shrinkable film.
2. Paper or fibre goods are placed in multi-storey yards and sealed with straps.
3。 Sealed metal containers and other cylindrical goods are placed in single or multi-storey yards, and wooden cargo covers are reinforced。
4. Paper products and textile goods that need to be protected against moisture and waterproofing should be placed in single or multi-layer staggered yards. Stretching or shrinking film packaging should be strengthened with angular support and cargo cover and partition.
5. One-way or multi-storey yarding of fragile goods, adding wooden supporting partition structure
6. Cylindrical containers of metal bottles or goods are placed vertically on a single layer, and reinforced structures of cargo frames and slabs are added.
7。 Multilayer staggered compaction yard for bags。
3. The Fixed Way of Pallet Bearing Goods
The main ways of fixing the goods carried by pallets are binding, gluing and binding, stretching and packaging, and they can be used in conjunction with each other.
4. Protection and Reinforcement of Pallets Bearing Goods
After fixing the goods carried by pallets, they still can't meet the transportation requirements. The protective and reinforcement accessories should be selected according to the needs. Reinforcement and protection accessories are made of paper, wood, plastic, metal or other materials.
5。 Matters needing attention in the use of pallets in conjunction with forklifts and shelves
1。 In the process of using the pallet, the distance between the fork bars of the hydraulic truck and the forklift truck should be as wide as possible to the outer edge of the fork inlet of the pallet, and the depth of the fork inlet should be more than 2/3 of the depth of the whole pallet。
2。 Hydraulic trucks and forklift trucks should keep uniform speed in the process of tray movement, so as to avoid the damage of tray caused by sudden braking and sudden turning and the collapse of goods。
3、托盘上货架时，应保持托盘在货架横梁上地平稳放置，托盘长度应大于货架横梁外径50mm以上。冷库中或是高强度使用环境时适合选用哪种塑料托盘? 正负40℃，不能用聚丙烯做的 聚丙烯这种材料不能抗低温。如果您在冷库中托盘需要上货架的话 最好选用双面托盘， 货没有这么重可以选择田字的或者川字托盘 。另：在低温环境下使用，实践证明，改性聚丙烯可以完全胜任。改性聚丙烯为聚乙烯与聚丙烯的高温不完全聚合产物。他兼具了聚乙烯的任性，聚丙烯的耐低温，物理性质稳定，抗磨耐摔。大型化工企业，低温冷库等环境一般建议使用该种材料。
3。 When the pallet is on the shelf, the pallet should be placed steadily on the cross beam of the shelf, and the pallet length should be greater than the outer diameter of the cross beam of the shelf more than 50 mm。 Which kind of plastic tray is suitable for cold storage or high strength environment? Polypropylene, which can not be made of polypropylene, can not resist low temperature。 If you need pallets on the shelf in cold storage, you'd better choose double-sided pallets。 If the goods are not so heavy, you can choose Tian or Sichuan pallets。 In addition, the modified polypropylene can be used in low temperature environment, and the practice proves that the modified polypropylene can be fully qualified。 Modified polypropylene is a product of incomplete polymerization of polyethylene and polypropylene at high temperature。 It combines the waywardness of polyethylene, low temperature resistance of polypropylene, stable physical properties, wear resistance and fall resistance。 It is generally recommended to use this material in large chemical enterprises, low temperature cold storage and other environments。
Plastic pallets made of low-pressure high-density polyethylene can be used. Plastic pallets made from pure raw materials can withstand the low temperature of minus 30 C. At present, HMWHDPE plastics are generally used to blow moulding high strength blow moulding pallets by extrusion-blow moulding at one time, and their average molecular weight is about 350,000-400,000. This kind of plastic raw material has super adaptability to environmental temperature and can be used stably in the environment of - 40-40 C. It is the preferred plastic pallet for high strength use environment at present, because of its high strength. Blow moulding tray has high cost of plastic raw materials, high technical difficulty in processing, and long service life of products, which can reach 5 to 10 years. Although the price of a purchase will be higher, but the cost of comprehensive use is indeed lower. When high strength is needed, this kind of high strength blow moulding tray can be selected.
