ABSTRACT:
A gauge for installation and adjustment of an interlock mechanism in elevator systems includes a gauge body with a horizontal line level and a first and a second arms protruding from the gauge body. The first arm is sized to establish a horizontal distance between two rollers of the interlock mechanism in the closed position during the adjustment procedure. The second arm is sized to establish a horizontal distance between two rollers of the interlock mechanism in the open position during the adjustment procedure. The gauge ensures consistently accurate horizontal measurement between the two rollers of the interlock mechanism in both the closed and open positions and proper alignment of the interlock mechanism during the installation and adjustment procedures.
