Pneumatic hoist structure and function
A pneumatic hoist operates using compressed air as its power source, consisting of a structured design for efficient lifting tasks. Its main components include an pneumatic motor, which converts compressed air into mechanical energy, and planetary gears that amplify this energy for lifting heavier loads. The pneumatic motor drives the hoist's drum, around which a wire rope or chain is wound. The lifting mechanism, often equipped with a hook or lifting attachment, raises and lowers loads with precision and control. Pneumatic hoists are known for their reliability, smooth operation, and suitability for various industrial environments where electricity may not be ideal or available.
Overview
The schematic of pneumatic hoist outside structure
Air-cut protection: When the air source is cut suddenly, the brake will automatically lock the power transmission part to prevent the free fall of the suspended load.
Chain: Anti-corrosive calibrated chain contains enough alloy elements, its safety factor can each 5 times of the standard force.
Position limit device: When the load is lifted to the top, the position limit block can stop the continuous lifting and the brake will immediately take effect to ensure the safety.
Chain deposit bag: It can be customized to satisfy the specific demand or it can be changed into steel chain box
Standardized hook: It can be selected to use 360-degree rotary hook or bronze plated hook for special circumstances, the safety factor is 8 times of the standard pull strength.
Control handle: the push-button control handle the speed and rhythm of descending and ascending precisely and effectively.
Installation and adjustment: The adoption of instant plug-in of the main air inlet tube can make the installation and adjustment very simple.
Air-cut release lever: When the air source is cut, this control lever can safely lower the suspended load in the air.

Overload protection: When the load surpassed the rated load, the overload protection can shut down the machine and protect the machine's life span and prevent malfunctions.
Planetary gears: The two-level speed reduction mechanism can control the speed ratio accurately and effectively.
Brake mechanism: The bronze brake plate can prevent the danger of spark, the sensitive and reliable brake can ensure the reliability of operation.
Chain wheel: The high-precision wear-resistant chain wheel can provide smooth ascending and descending, the life span is long.
Distributing valve: The precise piston movement can control the amount of inlet air, thus the inner adjustment function can be realized.
Silencer: The internal silencer can effectively lower the noise to 82dB or lower.
Pneumatic motor: Low air consumption, low maintenance. High torque, faster lifting speed.
