Hand Chain Hoist

The working principle of the hand-operated hoist mainly relies on the coordinated work of human torque transmission, gear transmission, and braking device.

Hand cranked hoists transmit force to the internal gear system by manually driving the handle, converting it into the rotational power of the winch. The gear transmission system further amplifies torque to ensure smooth and efficient operation. The braking device quickly brakes the winch when the operator stops applying force, preventing heavy objects from falling or causing injury due to excessive rotation. 

The structural design of the hand-operated hoist emphasizes practicality and durability. The shell is usually made of alloy steel or stainless steel, which has good strength and corrosion resistance. The gear system is composed of precision manufactured gears to ensure smooth transmission. The design and positioning of the braking device aim to provide fast and reliable braking effect.

Hand cranked hoists have a wide range of applications, mainly in the following fields:

In the industrial field, hand cranked hoists are commonly used for lifting and transporting goods in factories and warehouses, such as pulling goods onto trucks or lifting them to heights.

In the field of construction: Hand cranked hoists are used on construction sites to lift large mechanical equipment and steel, assisting workers in roof installation, window lifting, and other operations.

In the field of metallurgy, hand cranked hoists are widely used in industries such as steel mills and foundries for lifting heavy equipment and furnaces. 

Ship maintenance: In ship maintenance, hand-operated hoists are used to transport items away from the deck, cargo hold, and other locations of the ship.

Other industries: Hand cranked hoists are also used in equipment installation, item lifting, and mechanical pulling in industries such as power, transportation, and postal services.

The characteristics of a hand-operated hoist include:

Small size and light weight: Hand cranked gourds are small in size and light in weight, making them easy to carry and use.

High lifting capacity: Its maximum lifting capacity can reach several tons, meeting most lifting needs.

Easy to operate, safe and reliable: The hand-operated hoist has a simple structure, is easy to use, and is equipped with multiple safety devices to ensure safe and reliable use.
