DESCRIPTION
Hoists described in this manual are powered by air, and with the use of a pendant control, are designed
to lift and lower loads. The hoists can be bolted or hook mounted to a trolley or permanent mounting
structure.
The air hoists are equipped with vane motors which act as the drive for the gear section. The output
from the gear section is transmitted directly to the load chain drive sheave.
Each air hoist contains a brake which is released by air pressure applied to an annular brake piston.
When the “UP” or “DOWN” control pendant button/lever is pressed air is sent to the brake. The brake
piston compresses the brake springs, releasing the brake. When the pendant “UP” or “DOWN”
button/lever is released the air is exhausted and the brake is applied.
