HSZ chain block questions buyers ask before ordering

This portable lifting device raises equipment and goods by pulling a hand chain. It suits equipment installation and loading or unloading work, including outdoor jobs and locations where no power supply is available. The unit can also be attached to a trolley as a traveling chain block for a monorail overhead conveying system, hand traveling crane or jib crane.

The range includes models from 0.5 to 30 tons: HSZ-1/2, HSZ-1, HSZ-3/2, HSZ-2, HSZ-3, HSZ-5, HSZ-10, HSZ-15, HSZ-20 and HSZ-30. Match the listed capacity to the load and lifting arrangement for the job. Send the load weight and lifting layout when requesting a quotation so the applicable model can be reviewed.

Standard lifting height is 2.5 meters for the 0.5, 1, 1.5 and 2 ton models. It is 3 meters for the 3, 5, 10, 15, 20 and 30 ton models. Minimum distance between the two hooks ranges from 270 mm on the HSZ-1/2 and HSZ-1 to 1,100 mm on the HSZ-30. Check the available headroom and the distance between the support point and the load before ordering.

For example, a maintenance team installing equipment under a low overhead support should compare the available space with the selected model's minimum hook distance. A warehouse planning to move the unit on a monorail should also confirm the trolley and support arrangement before purchase.

The listed pulling force to lift the full rated load ranges from 210 N to 475 N, depending on the model. HSZ-1/2 requires 210 N, HSZ-1 requires 330 N, HSZ-3/2 requires 390 N, HSZ-2 requires 330 N, HSZ-3 requires 390 N, HSZ-5 requires 420 N, HSZ-10 requires 450 N, HSZ-15 requires 475 N, HSZ-20 requires 450 N and HSZ-30 requires 475 N.

This figure helps procurement teams compare operator effort for the selected capacity. It should be considered together with the load, lifting height and physical arrangement of the work area.

The product uses a manganese steel ratchet made through a quenching process. Its double braking structure controls lifting speed. A roller bearing design guides the chain and supports smooth operation. The chain path is enclosed by a thickened alloy steel cover, while thickened embossed wall panels protect the lifting wheels from squeezing and collision.

Yes. The chain block can be attached to a trolley as a traveling chain block. This makes it suitable for a monorail overhead conveying system, hand traveling crane or jib crane. Confirm the trolley, support and hook dimensions for the intended arrangement before ordering.

Provide the load weight, required lifting height, available headroom, support or trolley arrangement, work location and required quantity. These details allow the model, chain configuration and extra lifting height requirement to be matched to the job. For extra lift, the range lists additional weight per meter from 1.7 kg to 30 kg, depending on the model.
