Product introduction

Winding Machine, light and small lifting equipment that uses a reel to wrap steel wire rope or chain to lift or pull heavy objects, also known as a winch. The winch can lift heavy objects vertically, horizontally or at an Angle. The winch is divided into manual winch, electric winch and hydraulic winch. To electric winch mainly. Can be used alone, can also be used as lifting, road construction and mine lifting machinery components, because of simple operation, large amount of rope winding, easy to move and widely used. Mainly used in construction, water conservancy engineering, forestry, mining, wharf and other materials lifting or flat tow.

 

advantage: Compared with traditional electric winches, hydraulic winches (hydraulic winches) have many advantages:

1. Overload protection

2. Impact protection

3. Explosion-proof performance

Product application

Structure

The winch converts electrical energy into mechanical energy through the motor 1, that is, the rotor of the motor rotates and outputs, decelerates by the triangle belt 2, shaft 3, gear 4,5, and then drives the drum 6 to rotate. The reel winds the wire rope 7 and passes through the pulley block 8,9, so that the crane hook 10 lifts or drops the load Q, converts the mechanical energy into mechanical work, and completes the vertical transport loading and unloading of the load.

 

Matters needing attention

broadcast

EDITOR

First, the use of the hoist precautions:

1, the wire rope on the drum should be arranged neatly, such as overlapping and oblique winding, should be stopped and rearranged. It is strictly forbidden to pull and step on the wire rope with hands and feet during rotation. The wire rope should not be completely released, and at least three circles should be retained.

2, the wire rope shall not be knotted, twisted, in a pitch more than 10% of the broken line, should be replaced.

3. During the operation, no one shall cross the wire rope, and after the object (object) is lifted, the operator shall not leave the hoist. Objects or cages should be lowered to the floor when resting.

4, in the operation, the driver and the signal operator should maintain good visibility with the lifting object, the driver and the signal operator should cooperate closely and obey the unified command of the signal.

5. In case of power failure during operation, the power supply should be cut off and the elevator should be lowered to the ground.

6, the work should listen to the signal of the commander, the signal is unknown or may cause accidents

The operation should be suspended until the situation is clear before continuing the operation.

7, the sudden power failure in the operation, should immediately open the knife, the delivery of goods down.

8. After completion of the operation, the material tray should be placed on the ground and the electric box should be locked.

9, steel wire rope in the process of use and mechanical wear. The local damage of spontaneous combustion corrosion is inevitable, and protective oil should be brushed at intervals.

10. Overload is strictly prohibited. That is, exceeding the maximum carrying tonnage.

11, the use of the process should be careful not to appear knots. Flattened. Arc wound. Erosion of chemical media.

12, shall not directly lift high temperature objects, for angular objects to add protection plate.

13, in the process of use, the wire rope used should be frequently checked, and the scrap standard should be scrapped immediately.

2. Scrap standard of hoist wire rope

The steel wire rope used in the hoist includes phosphating coated steel wire rope, galvanized steel wire rope and smooth steel wire rope

1, the diameter is reduced;

Diameter wear more than 40% should be scrapped, not more than 40% should be reduced coefficient use.

2, surface corrosion;

When the surface corrosion of the entire wire rope is obvious to the naked eye, the wire rope cannot be used.

3. Structural damage;

The whole strand of the wire rope broken should be scrapped, and the wire rope with broken wires should be used with reduced coefficient.
