The ratchet belt or the ratchet load belt is a load belt family, because this load belt does not have the ability to bear the load and can only ensure the safety of the load during the transfer operation. The ratchet belt is used only for load restraint. Not in cargo transportation. Ratchet belts are mostly used in vans, trucks, trailers, off-road vehicles, and for fixing and restraining loads on pallets.
Cargo belts consist of two parts: belt and ratchet, the belt has the task of closing and holding the load, and the ratchet has the task of fixing and securing the ratchet. This type of ratchet belt is made of polyester. Polyester for its structural features It is a good option for pe
