Set the load safety device according to the 360 degree rotation working table of the crane. Support correctly according to the working condition table crane , place the kidney horizontally. Lift the boom and rotate the upper gear ring to test point a. Fix the dial indicator bracket 3 on the slewing bearing 4, place the measuring needle in the middle of the test shaft Y (the middle of the raceway surface), and set the dial indicator 1 to "0".
During the operation of the winch, the function and wear of the brake, clutch and stop block shall be observed and checked at any time, and the fault shall be eliminated in time. If it is not used for a long time, it shall be used according to the newly installed construction lift or the inspection and test method after overhaul. The construction elevator shall be placed in a dry place during transportation and maintenance, and each part shall be provided with good moisture-proof and anti-corrosion measures.
Some wheeled crane The manual power takeoff is adopted and installed on the crane On the power take-off window of the drive. It is a three-axis gearbox. The big gear on the driving tower gear is always meshed with the power output gear of the transmission intermediate shaft. The power of the engine is input by the gear of the drive tower, transmitted by the gear of the intermediate shaft and the main shaft, and output by the connecting flange of the main shaft. The hydraulic pump is driven by a universal drive shaft. Move the shift fork shaft with the shift lever to move the gear of the sliding tower to complete gear engagement (meshing) and gear disengagement (disengagement).
Huai'an Crane Rental Company introduces the use of small cars in winter crane The main reason is to keep warm.

After long-term use, crane The oil inside flows back to the lower engine oil pan. Therefore, after a long time of crane engine, the upper part of the engine is not lack of oil lubrication.
For its active parts, the connecting parts should also be well protected against corrosion. The metal surface can form an oil film, which can resist temperature changes and damage. Huai'an crane The leasing company told you that you should apply a layer of grease after cleaning and lubricating with diesel oil.
