WCB-1 Chain Block Feature
1. Standard design clamp for vertical lifting of steel plates and steel structures. The spring-loaded tightending lock mechanism assures a positive initial clampingforce.
2. Clamp are equipped with a safety mechanism, ensuring the clamp does not slip when lifting force is applied and when load is bing lowered.
3. Manufactured from high quality carbon steel
4. Avoid snatch or shock loading
5. High frquency quenching of die forged special alloy steels gives greater durability to the cam.
