(1) classified by table top. There are four types: single-sided, single-sided, double-sided and airfoil.
(2) Classification according to fork-in mode of forklift. There are three kinds: one-way fork, two-way fork and four-way fork.
③ Classification by materials. Wooden flat pallet, steel flat pallet, plastic flat pallet, composite flat pallet and paper pallet. According to the preliminary investigation results of pallet professional committee of China Federation of Logistics and Purchasing 20 1 1 on many domestic pallet production enterprises, pallet use and sales enterprises, there are about160-200 million pallets in China at present, and the number is increasing at a rate of about 20 million every year. Among them, wooden flat pallets account for about 85%, plastic flat pallets account for 12%, and steel pallets, composite pallets and paper pallets account for 3% in total. The proportion of composite flat pallet and plastic pallet is relatively large.
(2) Tray. Trays can be divided into fixed and detachable types. Its basic structure is that there are steel columns at the four corners of the tray, and the upper ends of the columns can be connected by beams to form a frame type. The main functions of column tray are as follows: first, use columns to support heavy objects and stack them high; Second, it can prevent the goods placed on the pallet from collapsing during transportation and loading and unloading.
(3) box tray. A box tray is a tray with side plates on all sides. Some boxes have a top plate, others have no top plate. There are three kinds of box boards: fixed, folding and detachable. There are plate-type, grid-type and net-type fences around it, so the box-type pallet with fence-type fences around it is also called cage pallet or barn pallet. The box tray has strong protective ability, which can prevent collapse and damage to goods; It can load irregular goods that can not be stacked stably, and has a wide application range.
(4) Wheeled pallet. Compared with column tray and box tray, the lower part of wheeled tray has more small wheels. Therefore, the wheeled pallet shows the advantages of short-distance movement, self-loading and unloading or up-rolling and down-loading and unloading, and has a wide range of uses and strong applicability.
(5) Special tray. Because of the high efficiency, safety and stability of pallet operation, especially in some occasions where rapid operation is needed, the importance of using pallets is highlighted, so various countries have developed various special pallets, and here are just a few examples.
① Flat glass tray. Also known as flat glass container rack, there are many kinds. There are L-shaped single-sided flat glass fork, A-shaped double-sided flat glass two-way fork, hanging fork combination and frame type. During transportation, the pallet plays a supporting and fixing role. Generally, flat glass is placed vertically on the tray, and the glass should follow the direction of the vehicle to keep the tray and glass stable. ② Special pallet for tires. Tyres are characterized by water resistance and corrosion resistance, but they are afraid of squeezing and pressing. The special pallet for tires solves this contradiction well. By using the special pallet for tires, it can be stacked in multiple layers without extrusion or compaction, which greatly improves the efficiency of loading, unloading and storage. (3) long pallet. This is a kind of tray specially used for stacking long-sized articles, and some trays have multi-layer structure. After the goods are stacked, long shelves are formed. ④ Special tray for oil drums. It is a special-shaped flat pallet for storing and transporting standard oil drums. There are corrugated grooves or side plates on both sides to stabilize the oil drum and prevent it from rolling down. The advantage is that it can be stacked in multiple layers to improve the storage and transportation capacity.
(6) Slider: a flat plate with wings on one side or multiple sides. A floor for carrying, storing or transporting goods or products in the form of unit load.
Main parameters: length/width/height/length-width-height error/diagonal error/rated load/maximum stacking quantity/flexibility/surface anti-skid coefficient.
Category: single wing skateboard.
Two labels slip-two opposite skateboards with wings on opposite sides.
A skateboard with two wings, with wings on two adjacent sides.
A skateboard with wings on three adjacent faces.
Four-wing skateboard Four-wing skateboard A skateboard with wings on all sides.
(7) Flocking inner support: it is a plastic tray made of special materials. A layer of velvet material is pasted on the surface of ordinary plastic hard sheet to make the surface of the tray feel velvet, which is used to improve the packaging grade.
