Four operation functions of the circuit: Mobile electric hoist travel hook (hanging objects) can do up and down movements. The right half part of the dotted line in the figureis the operation of cranes in the original circuit. K1 ~ K4 are the original manual operation buttons. Now they are used to replace the relay contacts, SQ is the improving limiting switch. KM1 ~ KM4 are the AC relays that are used to control the motor to enhance the motor M1 and M2. It controls and rises the forewardandreversal rotation of hanging objects. The dotted lines ofleft halfpart inthe figure form the new radio remote control circuit. In the circuit, the four output ends A ~ D of TX315B1 receiving circuit canrespectively drive tubes VT ~ VT4.
