DHP-type electric hoist crane group operating handle

Group hanging electric  lift hoist  someone on the ground is controlled by the handle, the handle is divided into two kinds of single-speed and two-speed. Handle with rotary-reset mushroom head type emergency stop switch, convenient in case of emergency, the motor stops running fast.
Button on the handle using internationally Arrow logo symbol. In the opposite direction button to set a mechanical interlock. Handle with a soft thin wire suspended from the electrical box, the core to prevent the cable due to power-off button control voltage of 36V safe voltage, maximum distance of up to 100m.

According to group hanging electric  rope hoist  motion commands for manipulating the host earn cars with reversing electric hoist control lever operation.
1, for this operation, the master control lever hoist two manipulating the relationship: If manipulating hoist in the zero position on the control handle, can not operate the joystick earn vehicles and reverse, which is due to the mechanical linkage's sake, even in the manipulation stage, for converting electric hoist control handle switch and the total handle, the manipulation of electric hoist control lever beyond the zero position has mechanical linkage mechanism, so that the operator's turnover intentions can be passed to the host exactly
2, the host vehicle and reversing manipulation earn hoist control handle operating procedure is: first console conversion of cars and earn reversing switches, limit switches detect hosts with two joysticks relative position, in recognition of manipulating electric  Wire rope hoist  control lever in the zero position, the solenoid valve is energized so that the switching valve stem moves to change the flow direction of the working oil to operate felt side of the operating oil pressure, according to the zero switch, the drive and reverse drive operation earn electric hoist control handle.
