Abstract: A mast for a storage and retrieval machine; having several, preferably four support elements or supports, to which connecting plates are fastened in order to form a mast profile. Connecting plates are fastened in alternating fashion to the inside and outside of the support elements or supports on two opposite side panels of the mast to increase flexural and torsional rigidity, for which purpose the support element comprises corresponding fastening grooves on the inside and outside.

Abstract: A driverless transport unit, travel unit, and method for controlling a travel unit for a transport unit, in which a control signal for activating a travel unit is emitted by a controller in the transport unit, whereupon one or several electric motors of the travel unit are activated for driving wheels and the transport unit is moved forwards or backwards. The driving operation is monitored by a safety control/controller. Upon detection of a malfunction, in which driving operation of the travel unit or transport unit is continued on the basis of an emitted stop signal, or upon interruption of the energy supply, at least one blocking device is activated in the travel unit for stopping the travel unit or transport unit, respectively, wherein at least one gear, at least one gear wheel or directly at least one wheel is blocked via the blocking device.
