Tower Crane Knowledge sharing:


Composition of the hydraulic system, functional description of each component
1. Energy components
It supplies the pressure of the hydraulic system and converts the mechanical energy output of the original idea into the pressure energy of the oil, thus advancing the work of all hydraulic systems.

The most commonly used is the hydraulic pump, which supplies the hydraulic system with power.
2. Execute Widgets
The hydraulic energy is converted into mechanical energy installation, that is, hydraulic cylinders, to drive the movement of working parts. The most commonly used are hydraulic cylinders or hydraulic Motors.

3. Control components
Contains a variety of valves, such as pressure valves, flow valves and direction valves, used to control the hydraulic system's liquid pressure, flow(Tassel) and direction to ensure that the performance element achieves the expected work activities.
4. Auxiliary components
Refers to various pipe joints, tubing, fuel tanks, filters, pressure gauges, etc., which play a helping role in connecting, storing oil, filtering, and measuring oil pressure to ensure that the hydraulic system is solid, stable, and long-term.

5. Working medium

Refers to the oil that is subjected to pressure and transmits pressure in a hydraulic system, individually mineral oil, collectively referred to as hydraulic oil.


 


What is the reason and how to deal with the different noise when the tower crane rotary support is running?
In this article, the factory will analyze for you from the professional technical point of view: the reasons for the failure of the tower crane swing support, and how to deal with the problem.
1. Causes of failure: Poor lubrication of large teeth.
Solution: Go smooth.
2. Causes of failure: Inappropriate gap between large teeth and small gears.
Solution: Adjust the gap.
3. Causes of failure: Damage to the rotating body or isolation block.
Solution: exchange damaged parts.
4. Causes of failure: pitting and peeling of the Raceway surface.
Solution: rest the Raceway.
5. Cause of failure: The pretightening force of high-strength bolts is inconsistent and the difference is large.
Solution: adjust the preloading force.

 

What about the tower hook? What are the causes and how are they disposed of?
