The MC56-9 hydraulic excavator considered the convenience of maintenance in the middle and late stages of the equipment at the beginning of the design plan, and the entire equipment can be maintained on all roads. The fully-opening front, rear, left, and right hoods and side doors take into account the convenience of component inspection and maintenance; in addition, find centralized lubrication for internal lubrication points, and methods such as high-altitude lubrication points lead to inferiority, which greatly reduces maintenance and maintenance time; rotating motor slows down The gear oil self-lubricating method is selected for part of the gear, which reduces the maintenance cost in the middle and later stages.
1 After opening the hood, the maintenance of the diesel engine and nearby notes can be carried out
A) The opening angle of the hood is enlarged, and road maintenance can be carried out while standing;
B) The hood can be opened automatically after opening to a certain angle of view, which is convenient and labor-saving;
C) The cylinder is configured to securely lock the organization, and the gear can be locked after the hood is completely opened;
D) Diesel engine fuel filter, oil filter, air filter and other basic maintenance parts can be maintained very conveniently.
E) The pressure measurement of the main valve, the main pressure measurement, the generator set, the starter motor, the fuel pump, the removal of the water dispersion and the protective net, the water discharge of the storage tank, etc. can be easily maintained by opening the hood.
2 Opening the side door can carry out the inspection and filling of the water level of the auxiliary water tank, the inspection of the liquid storage tank, the maintenance of the oil return pipe, etc.
3 Some maintenance on the bottom of the car can be carried out according to the removal of the fender or the rotation of the upper disc on the fender
A) Only need to unscrew the anchor bolts and rotate the disc to carry out maintenance. This kind of design scheme greatly saves maintenance time and reduces labor efficiency;
B) According to the rotating elliptical disk, the engine oil drain, the maintenance of the fluorine pipe and the oil pipeline can be carried out;
C) According to the disassembly and assembly of a small fender, the main filter element can be removed and replaced, and the hydraulic oil filter element can be refueled and other maintenance;
D) The tightening of the refrigeration compressor transmission belt can be carried out immediately according to the drilling of the mudguard, without disassembly.
4 The side of the human body can carry out the chain rail tension adjustment, the disassembly and replacement of the travel motor reducer oil, and the lubrication of the rotating system software.
A) When adjusting the chain rail tensioning, it must be carried out according to the provisions of the application maintenance and use instructions. It is not necessary to carry out actual operations such as tightening the grease nipple, otherwise it will cause accidental injury;
B) Pull the lubrication of the slewing bearing and the abs gear ring to the side of the human body, which is convenient and quick to maintain. The gear oil self-lubricating method is used for the rotating motor reducer, and no maintenance is required;
C) The software lubrication of the rotating system is carried out once every 250H, and there is no need to charge frequently.
5 Open the front hood to carry out maintenance of car relays, batteries, etc.
A) Expand the opening angle of the front hood, and carry out road maintenance while standing;
B) The hood can be opened automatically after opening to a certain angle of view, which is convenient and labor-saving;
C) The cylinder is configured to securely lock the organization, and the gear can be locked after the hood is completely opened;
d) The centralized layout of automobile relays and other electrical components makes maintenance and replacement convenient; the main power switch, battery, wet dust collector, etc. are also centralized in the hood, which is convenient and quick to maintain and maintain; in addition, a manual grease gun support is designed. Rack, with a convenient manual grease gun usually placed.
6 Maintenance such as fuel filling and breathing valve removal can be carried out above the human body
7 Standing on the road, all lubrication points of equipment and bulldozers can be maintained at work
A) The lubrication point on the rear side of the stick hydraulic cylinder is lowered, which is convenient for road lubrication;
B) The U-shaped plate is welded with the oil mark around the bucket and the bulldozer, which can reasonably protect the oil cup and clear the oil mark.
