Infrastructure projects in recent years, all over the world continue to increase, related policies introduced gradually for construction machinery industry, engineering mechanical UNDERCARRIAGE will continue to rise, and each big brand in order to seize market, price competition is more intense, which makes many repair shops and end users do not know should how to choose the brand of excavator and bulldozer UNDERCARRIAGE, PINGTAI engineering machinery company is a professional production of SPARE PARTS manufacturers, according to many years experience of the operation characteristics of excavator and bulldozer classification, and on the characteristics of their respective, introduced in brief.
First, according to the different driving modes, it can be divided into two kinds: internal combustion engine driven excavator and electric drive excavator.Electric drive excavator is mainly used in high altitude hypoxia and underground mines and some other flammable and explosive places. Compared with internal combustion engine drive excavator, its mobility is poor. Second, according to the different ways of walking, it can be divided into crawler excavator and wheel excavator.Crawler excavator is widely used. It can be used in mines or in places with bad working conditions. It has strong cross-country ability, but the mobility deviation and the price is higher than the wheel type.Wheel excavator investment is small, the speed of action is fast, but the scope of use is narrow, mainly by road administration or urban engineering, and the climbing ability is poor. Third, according to the size of the different, can be divided into large excavators, medium-sized excavators and small excavators.Generally, the following 20 tons belong to small excavators, between 20 tons and 30 tons belong to medium-sized excavators, and more than 30 tons belong to the category of large excavators. Fourth, according to the bucket to points, can be divided into shovel excavator and backhoe excavator.The shovel excavator is more used to excavate the material above the surface, the backhoe excavator is more used to excavate the material below the surface, and the bucket of the shovel excavator is bigger than the bucket of the backhoe excavator of the same equivalent.. Fifth, according to the different transmission mode, it is divided into hydraulic excavator and mechanical excavator.Hydraulic excavator by hydraulic cylinder operation, is a kind of multi-functional machinery, is widely used in transportation, mining and other machinery construction, quality and quantity, in improving labor productivity plays a significant role;The mechanical excavator is operated by the wire rope and the gear and the runner. It is to excavate the material higher or lower than the bearing surface with the bucket, and load it into the transport vehicle or discharge it to the stockpiling yard. The material excavated is mainly soil, coal, sand and the soil and rock after the pre-loosening.
UNDERCARRIAGE as a important part in the avoid, it let more excavator and bulldozer can adapt to working environment, but also to protect the role of excavator and bulldozer guide IDLER AND SPROCKET, leading to the degree of wear and tear is bigger, but some people change tracking some time is very short, usually by the track maintenance, today is a major maintenance should be paid attention to track and how to share.
TRACK CHAIN LINK should keep clear of in time: usually when excavator and bulldozer work, there will be some debris caught in TRACK CHAIN LINK, such as soil, stones, weeds, plastic bags and so on, if not often cleaned up, the clutter is compressed with the continuous rotation of TRACK CHAIN LINK between guide IDLER, SPROCKET and track, which tracks were constantly stretch.In the long run, the chain rail will eventually break because it cannot bear the tension.If the debris falls into the chain rail, it will lead to the guide ROLLER, the load ROLLER is not under control, at this time the continuous track will be easy to break, UNDERCARRIAGE wear will greatly increase.
Improper walking route selection: usually drivers work environment more for uneven ground, if the driver at random walk, do not pay attention to the road, or often walk on the way of more than 30 degrees slope, and make some looking at very cool driving skills, such as the bucket into the soil by the bucket arm contractility force power walking behavior will increase the wear and tear “of the machine, this kind of behavior will make a certain part of the increased pressure on track, increased wear life of the track to reduce long before.
Improper selection of parking apron: parking should be paid attention to when off duty, and must not be parked at will because of the desire to get off work. It violates the safety operating norms, especially in the apron that is not easy to be placed, and the long-term stress is uneven, and the track is more likely to be cracked and broken.
Despite these precautions, you should also be careful not to skimp on the butter when it is served.Only the safety standard operation can lengthen the service life of the excavator and bulldozers
