In engineering construction and ore mining, dump trucks have always played an important role. They are usually overloaded, in poor working conditions, and have great wear and tear. Therefore, the general service life of dump trucks is about 3 years, and the cost of replacing a dump truck is very high. In order to make your car last longer and earn more money for yourself, this time we have prepared a dump truck maintenance secret for you, hoping to be helpful to you.
The main difference between dump trucks and general vehicles is the lifting function. The hydraulic cylinder is crucial, so it is very important to check the hydraulic system.
(1) Check the hydraulic oil level of the dump truck. If it is insufficient, replenish it in time. Check whether the hydraulic system is damaged or leaking. If necessary, deal with it in time;
(2) Pay attention to and check whether the connection and fastening between the upper and lower supports of the hydraulic cylinder of the dump truck, the connecting rod mechanism and other components are reliable. Observe whether the moving parts and their adjacent fixed parts are abnormally damaged or deformed;
(3) Check the condition of the dump truck compartment, subframe, spare tire rack, etc., and pay special attention to whether the welds are open or cracked;
