ABSTRACT:
An elevator work station having an upright back with a top and a bottom and a pair of stanchions that connect to the top and to the bottom. Each of the stanchions has a longitudinal slot that traverses the length thereof. A base is generally secured normally to the upright back, more particularly to the stanchions, for supporting the upright back in a generally upright position. A work station is slidably secured to and along the upright back, more specifically within the slots of the stanchions, such that the work station can travel generally from the top of the bottom of the upright back to the top thereof. A work station movement control is mounted to the work station. The elevator work station is provided with a pair of pedals which when pedalled in a predetermined direction can raise or lower the work station. The pedals control a cable that extends from the top of the upright back to a winch member that is controlled by the pedals. As the operator pedals the pedals and takes in the cable, the cable becomes shorter which causes the work station to travel up. The work movement control determines the direction of travel of the work station.
