AC Electric Hoists
(Lifting)
Our Columbia AC Electric Hoists feature compact and efficient transplant reductions that require less input power, increase production while minimizing hoist size and weight. TEFC, UL-listed brake motors stay cooler during long duty cycles and their load holding brakes apply automatically.
Sealed construction keeps gears, shaft surfaces and bearings lubricated – no pillow blocks that require greasing. Modular design allows drum size changes and a wide range of gear ratios and motor sizes provide the performance required for your application. A full selection of options from single-speed drum switches to synchronized muli-unit/multi-axis systems put you in full control of your AC Electric Hoists.

Application Considerations
Determining the required line pull is the most important factor in selecting the proper winch or hoist for your application.
Line speed is the distance the load travels over a given amount of time.
Horsepower is a measurement of the rate (line speed) at which work (line pull) is performed.
Travel distance is the distance the load must move. Determining travel distance is more difficult in positioning systems, when using multiple pieces of line or when line stays in the system.
Wire rope size is determined primarily by the weight of the load being pulled or lifted.
The duty cycle of a winch or hoist is a measurement of how often it is used in a given amount of time.
To prevent excessive wire rope wear and damage and ensure the safety of operators, a location that permits proper fleet angle is necessary to let the wire rope spool uniformly onto the drum.
The temperature, humidity, exposure to elements, ventilation, and elevation can all play in a role when specifying the proper winch or hoist for the job.
