China Hand Cranked Hoist - Durable Hand Hoist & Wire Tensioner from Reliable Suppliers and Factory
โ๏ธ Working Principle
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.

โ Frequently Asked Questions (FAQ)
Q What is the maximum lifting capacity of a hand-operated hoist?
The hand-operated hoist is available in a range of lifting capacities from 0.75T up to 9T, making it suitable for most industrial, construction, and maintenance lifting needs.
Q What lifting heights are available for this hoist?
The standard lifting height is 3 meters. Additional options of 1.5m and 6.0m are also available to accommodate different working environments and requirements.
Q What materials are used in the construction of the hand-operated hoist?
The shell is made from alloy steel with a surface spraying treatment for corrosion resistance. The chain is G80 manganese steel, and the hook is a quenched manganese steel hook with thickened tongue pieces for added safety.
Q In which industries can a hand-operated hoist be used?
Hand-operated hoists are widely used across industries including manufacturing, construction, metallurgy (steel mills and foundries), ship maintenance, power, transportation, and postal services.
Q How does the braking system of the hand-operated hoist work?
The braking device automatically engages when the operator stops applying force to the handle, immediately stopping the winch from rotating. This prevents heavy loads from falling and ensures safe operation at all times.
Q What chain diameters are available and how does it relate to load capacity?
Chain diameters of 6mm, 8mm, and 10mm are available. Lower capacity models (0.75Tโ1T) use 6mm chains, mid-range models (1.5Tโ2T) use 8mm chains, and higher capacity models (3Tโ9T) use 10mm chains, with the number of chain rows increasing for heavier loads.
