From the Manufacturer
These air hoists are designed for commercial applications where air power is preferred. Great for use where harsh operating conditions such as a corrosive environment or high humidity could damage wiring in electric hoists. They have a range of 1/4 to 1-ton capacities. The self-cooling 100% duty-cycle motor will not overheat and the automatic brake system is tail mounted for easy inspection. There is a variable speed pull-cord control for precise load spotting and the upper and lower limit switches will prevent over-travel. Comes equipped with a chain container and option to include a pendant control for single-hand operation.
