1. Clarify usage requirements

1. Load weight: Determine the weight to be lifted (unit: tons or kilograms). The rated load of the selected hoist should be slightly greater than

Actual load (it is recommended to reserve 20% safety margin).

2. Lifting height: Measure the height that needs to be lifted, and ensure that the chain or wire rope of the hoist is of sufficient length.

3. Frequency of use:

· Occasional use (e.g. home maintenance): Economical model available.

· Frequent use (construction sites, warehouses): Choose a durable type.

4. Usage environment:

· Humid and dusty environments: Choose a waterproof and dustproof model (high IP rating).

· Corrosive environments (such as seaside, chemical plants): Choose stainless steel or anti-corrosion coating.

· Inflammable and explosive environments: choose explosion-proof type (such as copper alloy material).
