Chain Pulley Block FAQ
Our Chain Pulley Blocks are manufactured strictly in accordance with IS:3832 standards. This ensures structural safety, load-holding capability, and industrial-grade durability.
We exclusively use Grade 80 heat-treated alloy steel load chains. These chains are designed for maximum wear resistance and can handle heavy lifting cycles in tough factory environments.
Yes. Their portable and manual design makes them ideal for outdoor construction sites or maintenance tasks where electric power is unavailable. The rugged steel body protects internal components from harsh site conditions.
As a specialized chain hoist manufacturer, we offer both manual pulley blocks and Electric Chain Hoists with motorized travel for faster and more frequent lifting operations.
We recommend daily visual inspections of the hooks and chains, and a comprehensive load test every six months. Regular lubrication of the load chain is vital to prevent premature wear and friction.
