Tower Crane Knowledge sharing：

The purchase and use of tower cranes must ensure safety

The use of tower crane must ensure safety, once an accident, will cause casualties and property losses.

So the quality of the construction tower crane is the key, a lot of construction team seal do not understand the price is cheated, we can refer to the price of shandong tower crane to correctly understand the price of the tower crane purchase.

Users should face up to the safety work, tower crane construction machinery plant

1. Main steel structure parts of tower crane shall be free from deformation; Each transmission should be normal;

2. The oil level of each reducer and hydraulic oil tank meets the requirements, and the lubrication points are well lubricated;

3. The connection bolts of each main gun should be fixed; Each brake hinge point is flexible, brake shoe clearance meets the requirements;

4. Whether the wire rope lubrication, wear and winding meet the requirements;

5. All signals, alarm devices and lighting devices are normal and effective.

6. Before power transmission, check that the controller handle should be at zero; When power on, check the metal structure department of tower crane, there should be no leakage.

The tower crane accident can be completely avoided by taking necessary safety technical measures and operating in strict accordance with the safety regulations.

The safety precautions mentioned in this paper only serve as an supplement to the safe use of tower cranes, rather than a substitute for the applicable safety regulations, insurance requirements and relevant national and local laws, regulations and regulations.

The function of hydraulic jacking system of tower crane

The hydraulic jacking system of tower crane can increase or decrease the standard section through jacking and lowering tower crane jacket, so that the tower crane can increase or decrease with the change of building height, so as to meet the vertical transportation needs of buildings of different heights.

The system is mainly composed of hydraulic pump station, hydraulic jacking cylinder, lock valve and high-pressure hose.

During the jacking operation of the tower crane, the system needs to bear the weight of more than 30 tons of the upper structure of the tower crane, and the working pressure of the system is more than 18Mpa, which belongs to the high-pressure hydraulic system.

The system has the advantages of small size, light weight, large specific power and smooth operation, but at the same time it has the disadvantages of low transmission efficiency and easy to produce faults.

Because the hydraulic jacking system of the tower crane belongs to the pipeline circulation system with sealed pressure, the flow of oil in the pipeline, the movement of parts inside the hydraulic components and whether the seal is damaged are not easy to be detected, so it is difficult to analyze the cause of the fault and judge the fault part.
