The HSZ series is ideal for industrial production lines, construction sites, and logistics warehouses where reliable manual lifting and material handling are required.
The double braking structure provides a more secure grip on the load, preventing accidental slips and allowing the operator to control the lifting and lowering speed with higher precision.
Yes, while we offer standard heights of 2.5m to 3m, extra lift height can be added. Please refer to the 'Extra weight per meter' parameter in our table for specifications.
Manganese steel, combined with a professional quenching process, offers significantly higher wear resistance and fracture toughness, ensuring the ratchet doesn't fail under peak loads.
It utilizes a compact alloy steel thickened cover without curling edges and roller bearing guides, which ensures the chain flows smoothly without getting caught.
The HSZ series is versatile, ranging from a compact 0.5T capacity up to a heavy-duty 30T capacity to cover almost all general lifting requirements.
