Greenlee 651 12 Hook-Type Sheave, 4000 lbs Capacity

Using the Greenlee 651 Hook - Type Sheave is easy. First, make sure the cable puller's maximum pulling force is within the sheave's 4000 lbs maximum rated capacity. Attach the cable to the forged steel closure - type hook with the 1' opening. Then, let the 5' wide aluminum alloy sheave with self - lubricating bearings do its job for a smooth cable pulling process. When it comes to maintenance, regularly check the welded steel frames for any signs of damage. Clean the sheaves to keep them free from dirt and debris. And always ensure the self - lubricating bearings are in good condition. Also, never exceed the maximum rated capacity to avoid any safety risks and ensure the long - term performance of the sheave.
