PRODUCT FEATURES

INSTRUCTIONS & CAUTIONS

Installation and Mounting

When installing the K-Type double sheave block with hook, ensure the block is securely mounted to a stable lifting point. Always align the block with the direction of the load to prevent strain on the sheaves and bearings. Proper alignment ensures smooth operation and prevents unnecessary wear or damage to the equipment.

Rope Compatibility

Use only steel core ropes or ropes specified for this type of block. Double-check that the rope fits snugly in the sheaves and does not exceed the block’s working load limit (WLL). Incorrect rope size or tension could cause excessive wear or cause the rope to slip, reducing safety and efficiency during lifting operations.

Routine Maintenance and Lubrication

To maintain smooth performance, regularly lubricate the steel roller bearings using grease fittings. This helps reduce friction and prevents premature wear. Regular inspection for any signs of damage, like cracks or worn-out components, is crucial. Don’t forget to check for corrosion, especially if the block is used in harsh environments.

 

Load Capacity and Safety

Always observe the WLL marked on the block. Do not exceed the load capacity, as overloading can cause damage to the block, hook, or lifting system. The ultimate load capacity is four times the WLL, but this is only for safety testing. Consistently working within the rated WLL ensures the longevity of the block and safe lifting operations.

Needed these double sheave blocks for a major industrial project. The quality exceeded our expectations—especially the smoothness of the roller bearings. We had some custom size requirements, and Powerful Machinery delivered exactly what we asked for. No issues with performance, and the price was fair considering the quality. Excellent support throughout the ordering process as well.

We’ve been using Powerful Machinery products for a while now, and their double sheave blocks are top-notch. This order was no different. The blocks were robust and held up under heavy loads. We got them in a custom color to match our rigging equipment, and they look great. The only downside was the lead time was a bit longer than expected, but overall, a solid purchase.

As a logistics company, we rely heavily on the strength and durability of lifting equipment. The double sheave blocks we ordered from Powerful Machinery are perfect for our needs. We had to customize the blocks to handle larger wire ropes, and they did an excellent job accommodating that. Delivered on time, and the blocks have been working without any issues so far. Highly recommend for anyone needing reliable lifting hardware.

FAQ

The primary benefit of a double sheave pulley block is its ability to distribute the load evenly across two sheaves, reducing wear and tear on ropes or cables. It also improves mechanical advantage, making lifting and hoisting tasks easier and more efficient. With a hook, the setup is quicker and more versatile, reducing the time spent on setup and increasing productivity.

The double sheave pulley block offers greater mechanical advantage compared to a single sheave block. It allows for increased load capacity and smoother operation, reducing the strain on the rope and making it easier to lift or pull heavier loads. This efficiency is especially useful in industries where heavy-duty lifting and rigging are routine.
