Driving winch connection : Successful work starts with her

scheme winch connection: the principle of

main winch units: the main and auxiliary drum, gearbox, motor and launcher equipment.The cylinder is leading the working element.The principle of the winch is as follows: during the rotation of the shaft clockwise activated dog clutch that transmits torque through the gearbox main drum.There is a winding rope and lifting cargo.

When rotating counter-clockwise drum rotates in the opposite direction, after which the dog clutch disengages and the contacts of the switch.During the contact closure voltage is applied to the electric magnet auxiliary drum.Under the influence of the magnet coupling wheel is turned and transmits the rotation to the drum.Thus there is an auxiliary cycle of tightening the cylinder in the starting position.The cylinder is rotated by the support mechanism.

Note!For efficient and safe operation of the winch should be well fastened to the ground.

scheme together and connect

Before you start working, you must know how to connect the winch.To do this, you must be sure to examine the scheme and its connection to attach all the wires the device according to these schemes.If a connection is established to the mains voltage of 220 volts, then to the circuit board are attached three wires: the first - phase two - zero, and the third - grounding.If the connection is made to the three-phase network, connect the four wires: three phase conductors and one zero.

If you connect the winch and its drum rotates in the wrong direction, the two outer wires of the three cash, which included "phase", should be interchanged.Proper connection plays an important role in the safety and correct operation of the winch, so if you are unable to understand the wiring diagram, please refer to a specialist.

electric winch is powered by AC voltage of 380 V and 220 V networks.Also used equipment is 36 volts.These units are used in mining operations and are enclosed in an explosion-proof housing.If you follow a clear pattern, connect the device will have no difficulty, which will raise to the height of the pallet even bricks.

Dismantling in case of breakage

So how the winch, you know.But sometimes there are situations when it is necessary to disassemble the winch for cleaning or troubleshooting.Repair of electric winches can be carried out independently, knowing how to properly disassemble the unit.I understand it in the following order:

• First disconnected cable.To be turned out of the lock and bolt ties on the gearbox;
• reducer with body disconnected;
• brake cover removed for disassembling the gearbox;
• remove the actuator brake clutch.It rotates with the shaft, standing on the bearing;
• remove the drive shaft;
• With the help of pliers is removed the shaft brake and brake drum;
• unscrew bolts of gear, and it will be disconnected.

Important!Certified winch itself better to disassemble and repair, and to pass on the repair shop.

This demolition is completed, and you can find and correct the problem.After doing all the necessary work assembly takes place in reverse order.You can also do a partial dismantling of the winch for preventive maintenance: update grease, removal of dirt and dust.This should be done according to the operating instructions of the unit that allows you to use the unit without any failures, and this is very important when, for example, an urgent need to pick up a couple of dozen metal pipes.
