Hoisting motion: plain rotor resistance, AC single phase dynamic braking, counter torque lowering, opotor control, and creep speed. Bridge and trolley motion: simplified reliable circuitry; inverse time delay magnetic overload protection; time limit acceleration; speed control by series resistors; no volt protection; special unique plugging circuit with a voltage relay; CRCA sheet steel construction of the panel; 7 tank pretreated panels for extremely long life; and panels for indoor and outdoor protection.
