AC Electric Pulling Winches
(Pulling)
Every Columbia AC electric pulling winch features compact and efficient planetary reductions, requiring less input power and increasing production while featuring minimal hoist size and weight designs. Our AC electric winches include TEFC, UL-listed brake motors that stay cooler during long duty cycle and load-holding brakes that apply automatically.
Our AC electric pulling winches are engineered with sealed construction that keeps gear, shaft surfaces, and bearings lubricated and running efficiently. The modular design of Columbia winches allows versatility for the user to meet the performance demands of various applications by having the ability to change drum sizes with a wide range of gear rations and motor sizes. From single-speed drum switches to synchronized multi-unit/multi-axis systems, we offer a full selection of different options to put you in full control.

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.
