Wiring diagram is as follows:
Control hand two two buttons, one up and one down, *** four wires down switch, four wires with the highest resistance of the two connected to both ends of the capacitor, the remaining two wires a connection to the rise, a connection to the common line. Toggle switch is through the toggle switch handle to make the circuit on or off, so as to achieve the purpose of switching the circuit, toggle switch commonly used varieties of single-pole double-position, single-pole three-position, double-pole double-position, as well as double-pole three-position and so on.

Structural Principle
Small crane by the power unit and bracket two parts.
1, the power unit consists of motor, reducer, clutch, brake, rope cylinder and wire rope and so on. Motor for the evening magnetic single-phase capacitor motor, designed with a power failure that is the braking mechanism; motor is also equipped with a thermal switch to prevent the motor from overheating and burnt; reducer for the two-stage gear reduction, solidly connected to the motor; clutch, brake and the fly cylinder is installed as a single unit, but the clutch is in the state of disengagement, it can be realized rapid descent, the operation of the brake can be controlled by the speed of the descent in order to avoid the impact.
2, the power unit shell front of the open hole can be used to install a hair dryer, the user can be equipped with a hair dryer according to the need for forced cooling. The shell itself has a tool box with clutch handle, special wrench with brake handle, jack nut washer, rod top cap, push button starter, travel switch, electric wire and instruction manual.
3, the bracket part of the screw, jack nut and upright rod composed of the main rod and rotating arm. The rotating arm can rotate 360 degrees on the main rod, and there is a travel switch at the end of the arm to prevent the lifting over position accident caused by the operation error or button malfunction.
4, the operation of the button starter to realize the motor forward and reverse rotation can be coiled wire rope, release, and through the bracket part of the pulley lifting, lowering objects to complete the lifting operation.
Tips
After the machine is installed, there is one person on the top and one on the bottom to carry out the lifting operation. In the process of using the machine, you should pay special attention to the following two points:
1, after the first lifting, tighten the jack nut again. In the subsequent lifting operation, should also often check whether the jack nut is loose.
2, the clutch combination and disengagement operation must be carried out in the no-load state, and to ensure that the stroke to for.
3, not allowed to disengage the clutch slipping with load.
