INSTRUCTIONS & CAUTIONS
Proper Installation
Before use, ensure the pulley block is securely mounted. Attach it to a stable anchor point using the swivel oval eye or hook top for easy connection. Make sure the rope is threaded correctly through the sheaves, and double-check the positioning for smooth operation.
Regular Inspection for Wear and Tear
Inspect the block, especially the iron sheaves and bronze bushings, for any signs of wear or damage. Regularly check for corrosion or cracks in the galvanized malleable iron body to ensure the pulley block is functioning safely. Replace worn parts immediately to avoid any accidents.
Load and Capacity Limits
Never exceed the Working Load Limit (W.L.L.) marked on the block. Always calculate the total load, including dynamic forces, to ensure the block can handle the weight safely. Overloading could damage the pulley or cause failure during use, leading to potential injury or equipment damage.
Correct Rope Type and Maintenance
This pulley block is designed for use with fiber ropes. Ensure the rope is in good condition, free from fraying or damage. Regularly lubricate the bronze bushings to minimize friction, ensuring smoother operation and extending the lifespan of the pulley.

OUR REVIEWS
FAQ
What makes galvanized double sheave pulley blocks better than others?
A galvanized double sheave pulley block is a durable lifting tool made of galvanized malleable iron with two sheaves for increased load capacity. It’s ideal for handling heavy-duty tasks, offering smooth and efficient operation in tough environments.
How do I calculate the load capacity of a double sheave pulley block?
The load capacity is determined by the block’s Working Load Limit (W.L.L.). This rating indicates the maximum load the block can safely lift. Always ensure you don’t exceed the W.L.L. of the block, and consider the weight of the load and any dynamic forces. For optimal safety, consult the specifications or our team for guidance based on your lifting needs.
What is the difference between a single sheave and double sheave pulley block?
The main difference is that a double sheave pulley block features two sheaves, providing more lifting capacity and smoother operation compared to a single sheave pulley block. Double sheaves are ideal for heavier loads, allowing for more efficient lifting without compromising safety.
How fast can I receive a customized galvanized double sheave pulley block?
Custom orders typically take around 30 days for production, depending on the specifications and quantity. We offer efficient logistics to ensure timely delivery. For urgent projects, feel free to contact our team, and we’ll work with you to meet your deadlines as best as possible.
