Tower Crane Knowledge sharing：

Maintenance of hydraulic climbing system of tower crane

Oil and grease according to the lubrication table and clean the inside of the oil tank.

After the pressure of the overflow valve is adjusted, it shall not be changed at will. Before each climb, check whether the pressure is normal with the oil pressure gauge.

3 should often check whether the pipe joint of each department is tight, no oil leakage phenomenon.

4. Oil filter should be checked frequently for blockage, and the tower crane should check whether the adjustment value of the safety valve changes after use.

Oil pump, cylinder and control valve should be repaired in time if oil leakage is found.

6. When starting the oil pump for the first time after final assembly and overhaul, check whether the inlet and outlet are connected to each other, whether the rotation direction is correct, and whether there is air leakage in the suction pipeline.

 Then test the oil pump by hand, and finally start and test the oil pump within the specified speed.

When the tower crane is started in winter, it should be opened and closed for several times. The tower crane will not be officially used until the oil temperature rises and the control valve ACTS flexibly.

broken wire at the end of lower tower crane wire rope is discussed

Broken wire at the end of tower crane wire rope is a common problem in tower crane operation. How to avoid this kind of circumstance to appear, do protective measure in advance? When wire breakage occurs at or near the end of the rope, even a small quantity indicates a high stress in this part, which may be caused by improper installation of the end of the rope.

If the length of the rope allows, the broken parts should be cut off and re-installed properly. There are two main cases of wire breakage at the end of tower crane wire rope

1 increase rate of broken wires

In some applications, fatigue is the main cause of wire rope damage, broken wire is in use after a period of time began to appear, but the number of broken wire gradually increased, the time interval is getting shorter and shorter.

In this case, in order to determine the rate of increase of broken wires, the increase of broken wires should be carefully examined and recorded. The determination of this rule can be used to determine the future date of wire rope scrap.

2. Local aggregation of broken wires

If the broken wires close together to form a local aggregation, the wire rope should be scrapped. If the broken wires are concentrated in the length of the rope less than 6d, or concentrated in any rope strand, the wire rope shall be scrapped even if the number of broken wires is less than the listed value.
