Tower Crane Knowledge sharing:
Tower crane installation and disassembly help equipment-how to choose the mobile crane?
Mobile cranes are used as auxiliary equipment in the installation and disassembly of Tower cranes. Mobile cranes include car cranes and crawler cranes.
When choosing auxiliary lifting equipment, it is necessary to comprehensively consider its lifting height, amplitude, Heqi weight and other functional parameters to satisfy the tower crane installation and removal operation request.
The longer the crane's boom is extended, the greater the lifting height, the smaller the lifting weight; The starting weight decreases accordingly.
Prior to the erection and disassembly of the crane, a suitable working position for the auxiliary lifting equipment should also be selected according to the conditions of the installation and disassembly site of the crane.

When the tower crane is dismantled, the self-rising tower crane should be lowered by the county itself, so that the tower crane is reduced to a minimum status, and then the auxiliary lifting equipment is used to dismantle it.
A Simple Method for Differentiating the Quality of Hydraulic Oils without Special Detection Instrument
The quality of hydraulic oil not only affects the performance of construction machinery such as tower lifting, but also causes serious damage to hydraulic system parts.
1 Identification of Water Content in Hydraulic Oils
(1) Visual method: If the oil is milky white turbidity, it indicates that the oil contains a large amount of water.
(2) Combustion: Apply a small amount of oil to a clean, dry cotton yarn or cotton paper and light it with fire. If the "cracking sound" or flash phenomenon is found, it means that the oil contains more water.

2 Identification of impurity content of hydraulic oil
(1) Sensory identification There are obvious metal particles in the oil, and the presence of small particles is directly felt when squeezed with fingers; Under light, if there is a reflective flash point, it means that the hydraulic element has been seriously worn
If there is a large amount of metal debris deposited at the bottom of the fuel tank, it indicates that the main oil pump or motor has been seriously worn.
(2) Heating identification: For low-viscosity hydraulic oil can be directly heated in a clean, dry test tube. If precipitation or suspension occurs in the oil liquid in the test tube, it indicates that the oil liquid contains mechanical impurities.
(3) Filter paper identification: For highly viscous hydraulic oils, they can be diluted with pure gasoline and then filtered with clean filter paper. If there is a large amount of mechanical impurities(metal powder) on the current filter paper, the hydraulic element is seriously worn.

(4) Voice identification: If the entire hydraulic system has a large, intermittent noise and vibration, and the main oil pump emits a buzzing sound, even a piston rod "crawling" phenomenon, then observe the liquid surface of the fuel tank.
A large amount of foam can be found at the outlet of a tubing or transparent level meter. This shows that the hydraulic oil has been immersed in a lot of air.
