Description

Features:

1. The core is multi-layered and intertwined. Compared with the multi-layer rubber hoisting belt, there is no multi-layer structure. The core of the same cross-section is in the stretched or compressed state. Uniform, no surface peeling and interlayer peeling, ensuring a good running track when used, and not easily hitting the cylinder.

2. The whole core has a dense integrity after being immersed and plasticized, which ensures its excellent lifting ability, and the tear resistance and the anti-thread pull-through performance are better, which makes the connection between the bucket and the lifting belt stronger.

3. PVC’s inherent oil and chemical resistance makes it more resistant to oil, corrosion, moisture and abrasion than rubber lifting belts.

4. It has light body, firm structure, low driving power, flame retardant and antistatic performance, which makes the operation safety of the hoist more effective.
