Chain Hoist HSZ-C Type Manual Chain Block Made of G80 Grade Steel

Function and Application Scenarios

Chain Hoist a manual lifting device, the chain block relies on human power to raise or lower heavy loads. It is widely used in:

Industrial Environments: Factories, workshops, and warehouses utilize it to handle heavy machinery components, raw materials, or finished products, especially in areas where electric hoists are impractical.
Construction Sites: It is employed to lift building materials (such as steel bars, concrete blocks) in situations where precise manual control or power-free operation is needed.
Maintenance and Repair Work: For tasks like lifting equipment during repairs, its portability and manual operation make it a preferred choice.


Working Principle

The chain block operates based on the differential pulley principle combined with a ratchet-pawl mechanism:

When the operator pulls the hand chain (a component integral to operation, though not fully visible in the image), the internal gear system transmits the force to the load chain.
The ratchet and pawl prevent the load from slipping backward accidentally, ensuring safety. This mechanical design allows operators to lift heavy loads (up to 2 tons) with relatively little effort, making it highly labor-saving.

Key Features

Load Capacity: Rated for 2 tons, it is suitable for medium-duty lifting tasks, meeting the demand for moving moderately heavy objects.

Safety Certification: The “CE” marking signifies that it complies with European safety, health, and environmental protection standards, guaranteeing reliable and safe performance.
Portability & Compactness: Its small size and manageable weight make it easy to transport and use in various workplaces, even in confined spaces.
Manual Operation: It does not depend on electricity, so it can be used in power-free environments or areas with electrical hazards, enhancing its versatility.
Reliability & Maintenance: The mechanical parts are robust. Routine maintenance, such as lubricating the chain and inspecting gear wear, is simple, which helps prolong its service life.

Usage Precautions

To ensure safe and efficient operation:

Pre-operation Check: Inspect the load chain for wear, cracks, or deformation; check that the top and bottom hooks are not bent or damaged; verify that the ratchet-pawl mechanism functions smoothly.
Secure Suspension: Ensure the top hook is attached to a stable structure capable of supporting at least the rated load (plus a safety margin) to prevent collapse.
Proper Operation: Pull the hand chain at a steady pace; never exceed the 2-ton rated load to avoid equipment failure or accidents.
