Powerdrive is an electric drive unit for Mechrail, integrated in the rail system trolleys. The driving speed is stepless, adjusted by frequency converter and controlled by a joystick.

The drive unit can be used as drive unit in the X and Y directions, but also as brake system through additional control units on the manoeuvre handle.

Powerdrive is also available in a pneumatic version with an air-driven drive unit. It is used when electric media is not available or cannot be used, and is controlled in a similar way by for example a lever valve.
