Undercarriage, in particular one-rail under-flange carriage, for hoisting equipment

摘要

The chassis (1) has left and right wheels (3l, 3r) located at right and left side plates (5r, 5l) and running on a rail (4). The wheels arranged in series are seen in a driving direction of the chassis, where the wheels are driven by an electric motor (10). The wheels are drivingly connected to shafts, where the shafts are coaxially aligned to a rotation axis of the wheels. The right and left plates have hubs projected at an inner side, on which the wheels are mounted. Gear wheels are mounted on the shafts and mesh with one another over an intermediate gear wheel.
