附录ATray selection and with the shelves, forklift matchFirst, the selected tray Size:When used plastic pallets, according to the requirements of the project, the selected size will be different.1. First, consider the specifications and packaging of goods placed in the plastic tray method.For example: the European standard turnover box size is 600 * 400mm, 1200 * 1000mm pallet in place a layer of 5 in 1200 * 800mm layer placed on the tray 4, the general stacking 5 layers.2. Consider the pallet loading tools (such as containers, trucks, etc.).For example: If you are working round-trip or one-time use, you need to give priority to the width of 2300mm of integrated container shipping, for 1200 * 1000mm pallet, length 1200mm and width 1000mm to use a combination of place, must be selected to enter the fork 4.The tray on the 1200 * 800mm, 800mm width direction with two side by side.The pallet of 1100 * 1100mm width by 1100mm, placed 2, 2, or 4 to enter the fork into the fork can be.3. If used in the warehouse shelves, shelves to consider the size of width and depth, usually select the shelves each placed two trays of each cargo space, and allow access to the space of about 200mm.In depth direction as far as possible to give large size, this does not produce plastic pallets carrying capacity of the stringent requirements in order to save procurement costs.4. If the use of automated warehouse shelves, in addition to meet the above requirements, but also take into account the slip coefficient of the tray, the tray bottom with transmission equipment and chain, into the fork height, carrying capacity on the shelves, permanent deformation,length of surface deflection, the position of bar coding and RFID chips placed on other factors.5. Use plastic trays should also consider the size of generality, the size of the domestic common international standard for the 1210, 1208 European standard and T11 Japanese standard tray.Second, the choice of single and double-sided:1. Single use plastic pallets only one side, the surface grid of two peace-plate, the bottom of Sichuan fonts, font, or nine square field pad feet, according to carrying capacity and the use of different occasions into shelf series,standard series and ultra-light series of three standards.2. Sided plastic tray that the same structure on both sides of the tray, the surface grid plate of peace are two sides to exchange used, based on carrying capacity and the use of different occasions, the shelves are divided into two series and standard series standards.3. Use double-sided tray or trays should be based on the appropriate storage, loading and unloading equipment and state (such as the library type, rack type, stacking or placing the state, etc.) to determine.4. For the small footprint of the ASRS or high shelves, or electric stacker forklift to move vertically oriented occasion, single-sided double-sided shelf series shelf series of trays and trays can be chosen.5. If the three-dimensional library or load up on the shelves of 1T, but there is no ceiling shelves, the proposed shelf tray with built-in pipe.Steel structure steel tray built an effective solution to the product on the shelf load the greater the greater the weight, the old problem of high cost, more importantly, about the use of square steel tube wall thickness of 2mm rigid, reaching the shelves(ASRS) are horizontal and vertical deflection 10mm stringent requirements, while reducing the permanent deformation and reduce costs.6. For the area, mainly the large and the level of the occasion, if the manual handling hydraulic pallet truck is suitable for use single-sided tray.For stacking of goods to the bottom of the tray above and below the cargo coincide, the swastika with the end of double-sided tray or tray-type side is better.If using self-moving motorized pallet trucks are suitable for articles not connected with the bottom of the nine feet single tray.Third, the load requirements1. Dynamic load refers to the use of electric forklift or a manual hydraulic pallet truck can lift the maximum weight allowed.General shelf tray to load-bearing 1.5T-2T, the standard load-bearing pallet can 1T, lightweight tray dynamic load 0.5T.2. Static load refers to the stacking, the bottom of the plastic tray can bear maximum weight.General shelf tray to load-bearing 6T-8T, the standard load-bearing pallet can 4T, lightweight tray static 1T.3. Shelf load refers to the plastic tray packaging on the shelves when the maximum allowable weight.Must pay attention to dynamic load, static load, load library shelf load and establish the difference between carrying capacity and shelves of different structures, closely related to ambient temperature and storage period.General heavy trays on a shelf in load-bearing beams 0.7T-1T, standard tray loading 0.4T-0.6T.4. Shelf load permanent deformation of the plastic tray and deflection have certain requiremen
