AC Electric Lifting Hoists
Our Columbia AC electric lifting hoists feature compact and efficient transplant reductions that require less input power while increasing production and 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 multi-unit/multi-axis systems put you in full control of your AC electric lifting hoist.

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.
