For the maintenance of concrete pump trucks, the following are some key points:

The gear oil of the rotary reducer should be replaced every 500 working hours. In addition, all gear surfaces in the rotary reduction mechanism should be regularly greased for lubrication every 3 months. During the inspection, if dirt is found on the gear surface, it should be removed immediately to avoid gear damage, thereby reducing downtime and repair costs. At the same time, the slewing bearing should be lubricated with grease guns through the grease nozzle on the refueling seat every week. Once the nuts and bolts used for fastening are found to be loose, they should be replaced immediately to ensure construction safety and prevent accidents.

Grease nozzles are provided at the hinge points of each boom of the pump truck, the connecting shafts of the four legs and the support, and the turntable. These lubrication points should be oiled every 60 working hours to ensure full lubrication with grease until grease overflows. In addition, there is a lubricating oil cup on each of the two swing valve cylinder seats. Before starting pumping work, it is necessary to ensure that the oil cup is filled with grease and the cap is tightened for oiling and lubrication. During operation, the cap should be screwed and lubricated every 4 hours to keep the spherical friction surface in good lubrication condition.
