Abstract

The invention relates to an arrangement in an elongated working platform (2) which at each end is carried by a mast via a drive support (8) movable along the mast. The drive support includes an electric motor unit by means of which the drive support is drivable along the mast, said drive support pivotally carrying the corresponding end of the platform. At each motor unit an operating means for manual release of a motor brake for lowering the platform in case of power failure, is connected to a levelling device (24-38). The levelling device is arranged to be triggered in order to prevent movement of a drive support resulting in deviation of the platform from a position essentially corresponding to the horizontal position, said transmission being arranged to return the operating means to a position activating the motor brake, if the manual release of the motor brake causes triggering of the levelling device.
