The correct use and maintenance of cranes are closely related to safety production and the service life of cranes. Therefore, it is necessary to regularly inspect and test cranes. The inspection or testing must comply with the requirements of GB6067-85 "Safety Regulations for Cranes" and other relevant documents.

Lubrication: The quality and lifespan of the various mechanisms of a crane largely depend on regular and correct lubrication. Generally, the lubrication condition of each lubrication part should be checked every three months, and oil should be added or replaced.

The various mechanisms of this series of cranes adopt a dispersed lubrication method, so it is necessary to check the unobstructed oil cup at all times. The use of lubricating oil (grease) is related to the working characteristics and temperature of the mechanism. In places with high temperatures, oils or greases with higher viscosity can be selected.

The bearings in the large and small wheels can be lubricated with a mixture of No. 3 calcium based grease and heated oil, with a ratio of 4:1.

The gear of the reducer adopts oil pool splash lubrication. Gear oil (SYB1103-625) is used in winter and HL-20 is used in summer. The amount of lubricating oil injected into the box is measured with an oil needle, and the oil level should reach between the upper and lower markings of the oil needle.

The steel wire rope must be lubricated on time and correctly. The old oil should be cleaned with a cloth soaked in kerosene. It is absolutely forbidden to use metal brushes or other sharp tools to clean the dirt on the steel wire rope; The use of acidic or other highly corrosive lubricants is also absolutely prohibited.
