What type of hoist uses an air motor to provide input torque to a gear drive?

A pneumatic hoist utilizes compressed air to power an air motor, which in turn generates input torque that drives the gear mechanism. This type of hoist is particularly useful in environments where electricity poses a hazard, such as in wet or explosive atmospheres. The air motor converts the energy from the compressed air into mechanical energy, allowing for efficient lifting operations.

Pneumatic hoists are known for their speed, lightweight design, and the ability to operate in various environmental conditions without the risk of sparks, making them a safe choice for many industrial applications. The mechanism of converting compressed air into mechanical motion sets pneumatic hoists apart from other types of hoists, like hydraulic, electric, or manual hoists, which operate based on different principles.
