Frequently Asked Questions

Q: What is the maximum weight the HSZ chain block can lift?

The HSZ series offers a wide range of capacities, from a minimum of 0.5 tons up to a maximum of 30 tons, depending on the specific model selected.

Q: How does the dual braking system improve safety?

The dual braking structure provides redundant security, effectively controlling the descent speed and preventing accidental load drops, which is critical for worker safety.

Q: Is the HSZ chain block suitable for outdoor construction?

Yes, with its thickened alloy steel shell and manganese steel components, it is highly durable and designed for industrial production and construction environments.

Q: What prevents the chain from jamming during operation?

The HSZ series uses a compact, thickened alloy steel cover and roller bearing design that ensures the chain is guided smoothly, reducing the jamming rate to almost zero.

Q: Can I request a custom lifting height for the HSZ hoist?

Yes, while standard lifting heights are 2.5M to 3M, extra lift height can be added. Please refer to the "Extra weight per meter" parameter for specific model adjustments.

Q: What material is used for the ratchet to ensure durability?

The ratchet is crafted from high-strength manganese steel and undergoes a professional quenching process to make it wear-resistant and fracture-resistant.
