Explanation of the steps of wheel excavator maintenance

1. Wheeled excavator The spatial position of the dashboard.

In order to ensure high efficiency and reduce fatigue, the spatial position of the dashboard should allow the wheeled excavator operator to see all the instruments without moving his head and eyes, and without moving his body position. This reduces operator fatigue and makes the operation simpler, safer and more effective.

2. Wheeled excavator The instrument layout on the dashboard.

Wheel excavator

According to the assumed motion law, the dashboard of the wheeled excavator should be rectangular, with the long sides in the left and right directions, and the order of the meters on the dashboard should conform to the order of their readings. This is easy to operate, and you can quickly and accurately understand the operation of each part of the wheeled excavator. The more the instruments are connected to each other and the quality of the small wheeled excavators, the closer their arrangement is. The arrangement of the instruments should also take into account the logical connection between them.

3. The effective recognition range of the wheeled excavator dashboard surface

Experiments show that when the observation distance is 800mm, if the eyeball does not move, the 20-degree field of view is a good reading range, and the correct reading time is about 1s. When the horizontal field of view exceeds 24 degrees, the correct reading time begins to increase sharply, so 24 degrees is the limit of a good reading range.


Wheeled excavator dashboards are easily overlooked by buyers, and are actually very important to wheeled excavator drivers. A good dashboard design can reduce the burden on the operator, so that the operator can easily obtain the status of the wheeled excavator and direct its work. When we bought wheeled excavators, the consistent pursuit of cab space was not very reasonable. It is important to consider whether the overall cab layout is really reasonable, depending on your body, and choose a wheeled excavator where you can easily observe the dashboard.

Abstract: In order to make better use of wheeled excavators and prevent various failures, in daily use, more attention should be paid to the use and maintenance of wheeled excavators. Wheeled excavators usually perform first-level maintenance, second-level maintenance, third-level maintenance, and a four-level maintenance warranty system for major repairs.

Routine maintenance Check whether the lubricant, coolant, and battery level are normal, and add if necessary; check for oil, water, and electricity leakage, check the fastening of the main bolt at each part, and loosen the tightness in time; check the tightness of the V-belt, Use thumb pressure (about 6 kgf) and the belt in the middle, sag 5-6 mm, adjust or replace as appropriate; check meters, work lights, signal lights and switches; check or adjust the tension of the crawler, small wheel excavators, sag 25- 40mm; whether the operating performance of each lever is good; check the dust indicator, clean or replace the air filter element if necessary; check whether the bucket teeth are loose and residual defects; check whether the bucket teeth are severely worn, replace or repair (depending on Depending on the situation); add grease to the lubrication point of the working device; drain the water and sediment in the oil-water separator; check whether the electrical wiring has open circuit, short circuit, looseness, etc.
