| Zusammenfassung: | The utility model relates to the technical field of elevators, and discloses a novel forced elevator which comprises a top plate, an elevator shaft, an elevator car and a bottom plate, a permanent magnet synchronous gearless steel belt traction machine is fixedly installed at the top of the top plate, and an upper steel belt tensioning device is fixedly installed at the position, located on the left side of the permanent magnet synchronous gearless steel belt traction machine, of the top of the top plate. The novel forced elevator, the tightness of the elevator steel belt can be automaticallyadjusted through the upper steel belt tensioning device and the lower steel belt tensioning device; the friction force between the elevator steel belt and the upper rope returning wheel and the friction force between the elevator steel belt and the lower rope returning wheel are kept constant; the permanent magnet synchronous gearless steel belt traction machine drives the elevator car to move upand down through the frict |
