Crane, also known as crane, is a kind of multi action lifting machinery that can move materials vertically or horizontally within a certain range. It can be said that in modern social activities, construction machinery leasing has become an indispensable important logistics transportation equipment. This is not only because the use of cranes can greatly improve the quality of material handling, but also because the use of cranes has greatly improved the conditions for material handling, improved the actual production efficiency, and also increased economic benefits. So in recent years, Crane rental It is also widely used in ports, workshops, construction sites and other places. Due to the large mechanism, complex structure, large operation space and variable load of the crane, in the process of long-term use, due to the impact of vibration, friction and other factors, some parts and connectors will inevitably become loose, worn, aged, etc., affecting the normal operation and work of the crane, resulting in a large potential safety hazard, It will lead to the occurrence of safety accidents in crane operation, cause greater economic losses, and endanger the life safety of workers.

1. All kinds of machine parts, especially the equipment of hydraulic system, must not be attached with dirt. After the operation, dust and oil stains must be eradicated and cleaned.
2. Water and impurities in the hydraulic oil tank shall be removed from the bottom oil drain every half month, and all hydraulic oil shall be replaced every other year (or after 2000h of operation) (the oil change period can be properly extended if the oil has not changed). When the crane operates in a unique and harsh operating environment, the replacement period of oil should be shortened accordingly.
3. After the hydraulic oil has been operated for a long time, some condensate and sediment will occur, so it should be regularly discharged once a month. Drain the condensed water after the roller stops working overnight. Unscrew the oil drain plug at the bottom of the oil tank to let the dirty oil flow out until the clean oil is seen. Then install the oil drain plug and add fresh hydraulic oil.
4. No matter how long the operation time is, the hydraulic oil should be renewed at least once a year to avoid the deterioration of the hydraulic system. Before changing the oil, start the engine first to warm the hydraulic oil for drainage. As long as the normal protection is well done, the service life of the small crane will be increased and the safety factor will be higher in the normal operation.
