Hand chain hoists are used for horizontal movement operations, such as equipment installation, item lifting, and machine part pulling in industries like shipbuilding, power, transportation, and construction. Hand chain hoists have the advantages of being small in size, light in weight, easy to carry, and requiring minimal hand force. Hand chain hoists are used in electric power construction tasks, such as using them for lifting and transporting lines and equipment, tightening lines, etc. When selecting a hand chain hoist, it is essential to ensure that the weight of the load matches the tonnage capacity of the hoist to avoid overloading. Under this premise, choosing a lighter self-weight hand chain hoist can simplify the operation process and make it more convenient.
