A weight indicating apparatus is supported on the base for rotation relative thereto for indicating weight on the platform. A pinion is operatively connected to the weight indicating apparatus for rotating the weight indicating apparatus. A rack is movably supported on the base and operatively engages the pinion for rotating the same. A spring rope is connected between the beam and the rack for transferring movement of the beam to the rack to drive the weight indicating apparatus.
