Abstract
A running gear, for example, a single-rail lower-flange running gear for hoisting equipment, includes several wheels running on a rail, at least two of which are arranged one behind the other in the direction of travel of the running gear and adapted to be driven by an electric motor. The driven wheels are joined to at least two shafts, which are oriented coaxially to the axis of rotation of said at least two driven wheels.
