The G.A.L. Model MOHL, Master Operator High Speed, consists of a 1/2 HP, D.C. motor with heavy duty sprocket, chain, belt, and sheaves. It is capable of opening the car and hoistway doors simultaneously at a speed up to 3 feet per second. The power supply requirement is 230VDC, 500 VA, fused at 3 amps and it is also available for 120 VDC. Door speed is adjustable by means of resistor tubes located on the operator in a heavy duty steel box. The closing speed may be reduced to limit the stalled closing force and the closing kinetic energy to the values permitted by the ASME Code. The opening and closing limits of travel are cushioned by four steps of dynamic braking resistors.

The MOML and the MOHL door operators are identical with the exception of the motor. The MOML has a ¼ HP motor; the MOHL has a ½ HP motor. Installation, wiring, and adjustments are the same for both operators.
