Capstans

Standard AC Electric & Pneumatic Power

By wrapping soft line around its “head” and applying “tailing” tension that is only a small portion of the load to the free end of the line, a capstan can pull loads without storing line on a drum as do winches and hoists.

Our standard capstan units are available with either pneumatic or AC electric input power capacities from 1000 lbs. to 10,000 lbs. and line speeds up to 74 fpm. Higher line pull capacities and speeds as well as DC electric, self-contained and hydraulically powered units can be provided.

Vertical and horizontal mounting configurations are available to meet your installation and operating requirements.

Columbia capstans are in use in a wide range of industries including railway, marine and manufacturing applications. They are also widely used in the paper industry pulling felt rolls, significantly reducing downtime during routine maintenance.

If you are considering a capstan for a pulling application, please contact us to review and discuss your requirements at (503) 626-0654.
