Abstract

1,092,849. Endless belt conveyers. ELEKTROPROJEKT BERLIN VEB. July 27, 1966 No. 33744/66. Heading B8A. [Also in Division H2] The main switchgear for the drive of a crane, conveyer, or the like is adapted for remote control, either directly from a cabin, or indirectly through a radio link. When a selector switch aO1 is positioned for cabin control, a pushbutton b11 is actuated to energize relay d13 whereby coil a51 of the main switch is supplied with rectified current. A no-volt trip coil a52 of the main switch has its circuit completed through overload trip e, door contact b, push button b10, crane seat switch b1, and pushbutton b12. The switch b1 is shunted by holding contacts of the main switch. For radio control, the contacts of the selector switch are opened, and, if there is satisfactory transmission, a relay is operated to close contact d12/3-4 and open contact d12/9-10. The circuit for the trip-coil a52 is thus completed. Actuation of a further push-button in a portable control apparatus energizes a relay d11 to complete the circuit for the coil a51. In another arrangement, the main switchgear is driven by an electric motor which is moved automatically to a neutral position when the relay d12 is de-energized or the no-volt trip is actuated. After the switch-on operation is completed, the motor is actuated. After the switch-on operation is completed, the motor circuit is interrupted and is prepared for reversal. The position of the selector switch is indicated by warning lamps.
