The invention relates to a cart for transporting heavy objects (Z) on steps, in which in each case a triangular carrier (30), with wheels (31) mounted at its corners, is arranged at the two ends of an axle (13). In order to make transporting loads easier, the axle (13) is coupled via an intermediate gear (16 to 28) to a drive assembly consisting of an electric motor and an electromagnetic brake (14, 15). The drive assembly can be controlled via control switches (8, 34) in such a way that the drive force or braking force required for transporting loads up and down stairs is supplied by the drive assembly and thus the operator is prevented from being subjected to stresses. <IMAGE> |
