(1)Check the hydraulic oil quantity of dump truck, if there is insufficient, supplement in time, check whether the hydraulic system is damaged or leaking, if necessary, deal with it in time; (2)Pay attention and check the upper and lower support of hydraulic cylinder of dump truck, if there is insufficient, supplement 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 parts are reliable. Observe whether there is any abnormal damage or deformation of each moving part and its adjacent fixed parts;.
(3) Check the intact condition of the dump truck compartment, sub-frame, spare tire carrier, etc. Pay special attention to checking whether the welds have open welds, cracks and other phenomena;.
(4) Check the working or wear condition of the gear pump, extractor, hydraulic cylinder and other moving parts of the dump truck, and carry out maintenance, repair and replacement of wearing parts.
For the Sinotruck howo dump truck maintenance and maintenance, but also pay attention to the following points:
(1) The high pressure hose of dump truck must be replaced every two years, if the hose is found to be cracked and damaged or partially swollen it should be replaced in time;.
(2) The Sinotruck howo dump truck dumping mechanism should be frequently checked whether there is leakage and oil seepage phenomenon. When filling hydraulic oil, should check whether the filter installed at the refueling port is broken, and replace it when necessary to avoid impurities mixing in and accelerating the wear and tear of hydraulic components or early damage. Strictly prohibit the mixed use of different grades of hydraulic oil and filling does not meet the requirements of the instructions of the hydraulic oil.
(3) should always check whether the engagement and separation of the tipper and gear pump are normal, to avoid incomplete separation resulting in accidental lifting of the carriages. Under the working condition, it should also pay attention to whether the vehicle has abnormal phenomenon such as strange noise or high temperature, if necessary, exclude them in time to avoid the premature damage of the extractor, gear pump and valves.
(4) When overhauling the Sinotruck howo dump truck, check the working surface of the piston rod of the hydraulic cylinder to see whether there are bruises, scratches and other phenomena, if there is timely repair or replacement, otherwise the hydraulic cylinder working performance will be significantly reduced.
(5) Check whether the locking mechanism of the rear compartment plate of dump truck is reliable and adjust it to a reasonable angle of automatic opening and closing, so as to prevent the rear compartment plate from accidentally opening or not opening when lifting up and causing accidents; when dumping large materials, the rear compartment plate should be unloaded, so as to avoid crashing the rear compartment plate.
