A commonly used but misunderstood part of the the adaptive equipment found in many wheelchair vans is the electric linear actuator. This little device is often confused with a hydraulic cylinder but is actually a self-contained unit with a 12-volt direct-current motor, a gear box that transfers the motor's action to a ball-bearing worm screw, a clutch that prevents the motor from developing too much pressure against the worm gear, and a brake that holds the actuator's load at any given position in the operation cycle.
