HSZ 20-ton Chain Hoist

The HSZ 20-ton chain hoist is a heavy-duty manual lifting tool in the HSZ manual chain hoist family in Hebei Baiyi factory. Its main structure uses a high-strength G80 manganese steel chain, alloy steel gears, and a double ratchet braking system. The standard lifting height is 3 meters, but customization is also available upon request. The fully loaded chain pulling force is approximately 392N, and its own weight is approximately 100kg. It is widely used in power, construction, manufacturing, warehousing, docks, and other industries for the installation of heavy equipment and the loading and unloading of goods.

Key Selling Points:

1.Safe and Reliable: Rated load of 20T, with 8 rows of G80 manganese steel chains and alloy steel gears, providing strong load capacity. It has passed a 25-ton load test at the factory, and its safety factor fully meets international standards.

2.Safe Self-Locking: Employs a double pawl friction braking system, achieving self-locking during lifting/lowering/suspended operations, eliminating the risk of hook slippage.

3.Labor-Saving: Utilizes an optimized gear transmission ratio, requiring only approximately 40kgf of pulling force at full load, allowing for single-person operation.

4. Versatile for Multiple Scenarios: Can be used in situations without power, in confined spaces, or outdoors.

5. Long Service Life: The entire set of bearings and gears undergoes carbon heat treatment, making them wear-resistant and durable.

6. Precise Positioning: Precise positioning can be achieved through manual control of the lifting/lowering speed, meeting the needs of precision installation.

FAQ：

Q1: Can the lifting chain length be customized?

A: Custom-lengthened chains are possible, but require professional modification by the original manufacturer to ensure sufficient chain strength and smooth operation. Self-lengthening is strictly prohibited and may lead to safety hazards.

Q2: What routine maintenance is required?

A: Monthly inspection of the hook, chain, and braking system; cleaning of dust; when not in use for extended periods, apply lubricant to prevent rust and moisture, and store in a dry, well-ventilated place.

Q3: Can the HSZ 20-ton chain hoist be connected in parallel with other hoists to lift the same load?

A: Absolutely not. Different hoists have different synchronization characteristics, which can lead to uneven stress on various parts, localized overload, and potentially safety accidents.
