Wire rope core belt bucket elevator

The traction component of TDG hoist adopts high-strength steel wire rope core rubber belt, which overcomes the dynamic load generated by the chain and drive, is lighter than the chain, works more smoothly, and can achieve higher productivity at a faster speed. Under the same production conditions , The tape should have high working speed and light weight, which can reduce the line load of the material and the line load of the traction member, thereby reducing the size and weight of the whole machine. At the same time, because the tape has good elasticity and flexibility, it has a damping effect when the hopper is loaded. Due to the use of high-strength steel wire rope core tape, the lifting height and conveying of the hoist can be greatly improved, so the product has a good development prospect.
