Chinese tray standard and main specifications of existing trays

At present, China's pallet specifications are quite confusing. Except for the mechanical industrial systems using the 800mm×1000mm and 500mm~800mm pallets specified by JB3003-81 , in 1996 , the Ministry of Communications of China’s Ministry of Transport proposed the ISO6780 : 1988 “Main Traversing Flat Tray Sizes and Tolerances for Joint Transport” equivalent. Adopted as a national standard for Chinese trays. Later, the former State Bureau of Technical Supervision to GB / T2934-1996 standard series Symbol approved and published this equivalent standards, including the 1200mm × l000mm, l200mm × 800mm, 1140mm × l140mm and 1219mm × l016mm other four pallet specifications.

  In addition, regarding the pallet standard, China also has GB/T3716-2000 pallet terminology, GB/T16470-1996 pallet packaging, GB/T15234-1994 plastic flat pallet, and GB/T4995-1996 intermodal flat pallet performance requirement, GB/T4996- 1996 National Standard for Traversing Flat Tray Test Methods. Not only that, in China's Japanese- and Korean-funded companies, a large number of pallets with lvalue="100" unitname="mm">100mm×value="1100" unitname="mm">1100mm are still in use. All these indicate that China has adopted too many pallet standards. If it is not vigorously rectified, it will be difficult to effectively solve the problem of the unification of pallet specifications in China. According to a survey conducted by the Pallet Professional Committee, the specifications of pallets in circulation at present are rather messy. Including: value="2000" unitname="mm"> 2000mm × value="1000" unitname="mm">1000mm , value="1500" unitname="mm"> 1500mm ×value="1100" unitname="mm ">1100mm , value="1500" unitname="mm"> 1500mm × value="1000" unitname="mm">1000mm , value="1400" unitname="mm"> 1400mm ×value="1200" unitname= "mm">1200mm , value="1300" unitname="mm"> 1300mm ×value="1000" unitname="mm">1000mm , lvalue="200" unitname="mm">200mm×value="1000" Unitname="mm">1000mm , value="1200" unitname="mm"> 1200mm × value="800" unitname="mm">800mm , lvalue="200" unitname="mm">200mm×value=" 1100" unitname="mm">1100mm , value="1100" unitname="mm"> 1100mm ×lvalue="0" unitname="mm">000mm , value="1100" unitname="mm"> 1100mm ×value ="1100" unitname="mm">1100mm , value="1100" unitname="mm"> 1100mm × value="900" unitname="mm">900mm , lvalue="0" unitname="mm">000mm ×value="1000" unitname="mm">1000mm , lvalue="0" unitname="mm">000mm×value="800" unitname="mm">800mm , lvalue="200" unitname="mm" >200mm×lvalue ="200" unitname="mm">200mm , lvalue="300" unitname="mm">300mm×lvalue="600" unitname="mm">600mm , lvalue="300" unitname="mm">300mm There are dozens of specifications such as ×lvalue="100" unitname="mm">100mm . Among them, the specification of plastic trays is relatively centralized, mainly value="1100" unitname="mm"> 1100mm × value="1100" unitname="mm">1100mm and value="1200" unitname="mm"> 1200mm × Value="1000" unitname="mm">1000mm , which accounts for about 50 % of plastic trays . This is due to the fact that plastic injection molds are used in the production of plastic trays, and the cost of mold development is relatively high. The specifications of wooden pallets are relatively confusing. The current specification is mainly based on the use of the unit to customize according to the specifications of their own products. This is related to the relatively simple manufacture of wooden pallets. There are not many specifications for steel pallets, and they are concentrated in two to three specifications. They are mainly used for ports and other units that require relatively high pallet load capacity. In addition, during the survey, the Pallet Professional Committee also found that most of the companies now use flat four-way fork double-sided pallets, which account for about 60 % of the total pallet usage . The rest are flat two-way fork double-sided pallets, single-sided flat pallets, box pallets and column pallets. The use of special trays is relatively small. Box trays are now used for material handling in the company's production process and are basically not in circulation.
