An excavator is a earth-moving machine that uses a bucket to excavate related materials and load them into a transport vehicle or unload to a stockyard. The materials excavated by the excavator are mainly soil, coal, sediment and pre-pulled soil and rock. The development of excavators is relatively fast, and excavators have become one of the most important construction machinery in engineering construction.
Excavators are used in many ways,such as digging of trenches, holes, foundations;demolition with hydraulic claw, cutter and breaker attachments and drilling shafts for footings and rock blasting,etc.Excavators play an important role in engineering construction. Do you master the excavator operation skills? And how do we better maintain it to reduce damage? Here are several tips for your reference.
Excavator operation skills
The first thing to do is to confirm the surrounding conditions. When turning the work, understand the surrounding obstacles and terrain, and operate safely. When operating, confirm the front and rear direction of the track to avoid tipping or impact; ensure that the left and right tracks are in full contact with the ground to improve the dynamic stability of the machine.
*The inside of the hydraulic cylinder is equipped with a buffer device, which can gradually release the back pressure near the end of the stroke; if the impact load is received after reaching the end of the stroke, the piston will directly hit the cylinder head or the bottom of the cylinder, which is easy to cause an accident, so the end of the stroke should be Try to leave a gap.
* When loading and unloading heavy materials such as rocks, the material should be discharged near the bottom of the truck compartment, or the soil should be loaded first, then the rock should be loaded, and the high-altitude unloading should be prohibited to reduce the impact damage to the truck.
Excavator routine maintenance
Excavator maintenance, there are several aspects to pay attention to:
The oil and oil filter are replaced according to the specified maintenance cycle, which makes the engine last longer.
The air filter element is often inspected. When the outer filter element is gray, it is blown from the inside to the outside with compressed air. The air pressure should not be too large to prevent the filter element from being blown.
Replace the hydraulic oil, oil return filter, and pilot filter according to the specified maintenance cycle, and pay attention to whether there is any iron scrap or copper scrap on the filter.
When the breaker is used, the deterioration and deterioration of the hydraulic oil are accelerated, and the replacement cycle should be shortened.Do not work for a long time without oil.
After replacing the hydraulic oil or hydraulic components, pay attention to the air.
Pay attention to waterproof, do not involve deep water operation, do not flush the electrical device directly with water when cleaning.
Do not pile up debris in the battery box, especially metal tools, etc., which may cause fire.
Do not use wire copper wire instead of insurance, and do not replace it with substandard insurance.
When the excavator is parked for a long time, the battery line should be removed to prevent returning.
