Bulky than the heavy box, and needs set lever. Lever rod should use scalable, flexible, scalable and convenient. Pulley shaft separate product selection. Rotating flexible, mobile and convenient. When we received the custom-made trolley product can be determined by the following two points of superiority and inferiority .1 rod, hand lever repeatedly pull more excellent stretch observe whether light, flexible .2, Aluminum, on the road to drag the box to observe the movement speed, and whether there is abnormal noise and friction. inferior rod, pull slowly, custom Aluminum aerial equipment boxes, moving slowly. quality trolley, easy to move fast, rod good scalability. military tank according to customer requirements, can choose a variety of materials production of production, you can choose a multi-layer plywood, ABS board, aluminum, stainless steel, hollow boards and other materials, eliminating the need for tooling costs, and the general need to open the box of traditional mold, Beijing Aluminum chassis custom price, you can not select multiple materials. Military Box external structure: the multi-layer plywood PBS posted outside the fire board, ABS, aluminum, stainless steel interior items together to provide maximum protection, Hebei Aluminum manufacturers, strong impact force to prevent objects or damage caused by other factors.
