Hydraulic wrench is a tool often used in life nowadays, and has become a necessary tool for vehicle maintenance and industrial production with the advantage of "quick and easy". So for some common valve and flow control valve usually maintenance and maintenance and should pay attention to what? The reason for the pressure reducer failure may be due to over pressure or under pressure relief valve. It may also be because of the pressure of instability. These malfunctions may cause inconsistency in valve spool movement or poppet valve instability, which may also result in the mixing of air into the oil. In response to these, we can open the drain back pressure changes the small hole in the center of the spool to check the amount of oil inside. Next, open the tubing of the other control valves and take the air inside. Of particular note here is the pilot valve. Flow control valve failure may result in pressure correction device does not work. This may be due to dust in the spool or the hole in the sleeve caused by dust, in this case as long as the flow of the outlet pressure differential cleaning solution on it. Flow adjustment shaft back to tight. The cause of this condition may be due to dust on the adjustment shaft. Clean up here is very laborious, the general appliance root can not be cleaned there. We can take the measure of quantity so that he will start the six o'clock scale at the second increase in pressure and once he will deconvolve it. In addition to these, the hydraulic wrench should also pay attention to the directional control valve maintenance and repair. Manually found the stem of the oil seal leakage, which may be caused by the seal damage. This situation as long as the cylinder head open, replace the oil seal on it.

Hoisting Mechanism And Spare Parts

The hoisting mechanism for a Tower Crane typically consists of a combination of a motor, a gearbox, wire ropes, and a hook block. Here is a breakdown of its components and how they work together:

1. Motor: The hoisting motor provides the power needed to lift and lower loads. It is usually an electric motor that generates high torque to handle heavy loads.

2. Gearbox: The motor's rotational motion is transmitted to the hoisting drum through a gearbox. The gearbox helps increase the torque and reduce the speed of the motor, enabling the crane to lift heavy loads at a controlled speed.

3. Hoisting Drum: The hoisting drum is a cylindrical drum around which the wire ropes are wound. It is directly connected to the gearbox and rotates as the motor operates. The drum's size and design determine the amount of Wire Rope it can hold.

4. Wire Ropes:
The wire ropes are wound around the hoisting drum and connected to the hook block. These ropes are made of high-strength steel and have a high load-bearing capacity. Multiple wire ropes are used to distribute the load evenly and ensure stability during lifting operations.

5. Hook Block: The hook block is attached to the lower end of the wire ropes and is responsible for carrying the load. It consists of a pulley system with one or more sheaves, which allows the wire ropes to change direction and support the load securely.

During operation, the motor drives the hoisting drum through the gearbox. As the drum rotates, the wire ropes are wound or unwound, depending on the direction of rotation. This movement raises or lowers the hook block, allowing the crane to lift or lower loads.

The hoisting mechanism is controlled by the crane operator using various controls and switches. Safety features such as limit switches and overload protection systems are also incorporated to prevent accidents and ensure safe lifting operations.
