レーンの巻上巻下制御回路。 A crane in which the DC motor has a series winding circuit when hoisting and a shunt winding circuit when hoisting down, and the controller's notch operation turns on and off the contacts of the electromagnetic switch to increase or decrease the rheostat connected to the DC motor. In the hoisting/lowering control circuit, the relays for controlling each electromagnetic switch are predetermined so that each corresponding relay is energized in conjunction with acceleration operation of the controller and demagnetized in conjunction with deceleration operation. A timer is provided for each notch, and at the time of each acceleration operation, the relay on the next notch side can be energized after the time required for the DC motor rotation speed to rise from the energization of the corresponding relay. Features: Crane hoisting and lowering control circuit.
