Rail vehicle has work platform with telescopic support mounted rotatable in relation to machine frame and with platform rotatable relative to support through second rotary drive

摘要

The work platform (10) has a telescopic support (11) mounted rotatable about a rotational axis in relation to the machine frame (2) through a rotary drive. A lower end of the telescopic support is fixed on the rotary device at a distance from the rotational axis. The work platform is rotatable relative to the telescopic support about the longitudinal axis through a second rotary drive which is mounted at the upper end of the support. The rotational device is formed as a toothed rim rotatable about the rotational axis through a pinion.
