According to the operation instructions of the electric hoist, the operation of the main engine gaining and reversing operation of the electric hoist control handle is performed.
1. In this operation, the relationship between the two operating control handles of the electric hoist is: if the control handle of the electric hoist is operated at the zero position, the winning and reversing operation handles cannot be operated. This is due to the mechanical linkage. Even on the control console, for switching the electric hoist control handle switch and the total handle, the electric hoist control handle is operated outside the zero position and there is a mechanical interlocking mechanism, so that the operator's intention can be accurately transmitted to the host.
2, the host car and reversing operation of the electric hoist control handle operation program is: first convert the console to make the car and reverse the switch, with the limit switch to detect the host two joystick related positions, in the confirmation of the operation of the electric hoist After the control handle is in the zero position, the solenoid valve is excited, the handle causes the changeover valve to move to change the flow direction of the working oil, and the pressure of the working oil on the operated side rises. According to the zero setting of the changeover switch, the drive earns money. Reversing operation electric hoist control handle
