  Today, the   Excavator Manufacturer   will share with you some of the necessary knowledge of excavators. 1, it is not advisable to eat too much soil each time when digging, and the bucket should not be too fierce, so as not to damage the machine or cause an overturning accident. When the bucket drops, take care not to impact the track and frame. 2, The personnel who cooperate with the operation to clear the ground, level the ground and repair the slope must work within the turning radius of the excavator. If it is necessary to work within the excavator's turning radius, the excavator must stop turning and stop the turning mechanism before working. At the same time, the people on board and under the plane must take care of each other and cooperate closely to ensure safety. 3, Vehicles and pedestrians shall not be parked within the excavator loading range. If you unload the car, you should wait for the car to stop. After the driver leaves the cab, you can turn the bucket to unload

  Today   Bulldozer China Factory   introduces the correct way to use the crawler bulldozer. 1.Speed change and retreat When shifting gears, the throttle handle should be pushed forward to the low-speed idling position, and then the main clutch lever should be pushed to the front to disengage the main clutch. Due to the small brake in the main clutch, the power input shaft of the transmission stops rotating. . At this time, you can correctly shift the shifting benchmark to the required gear, and then put the forward and backward lever to the forward or backward position (when the bulldozer is forward, pull the forward and backward lever back, and push it forward when back). After being in gear, pull the throttle handle backwards to increase the engine speed, and connect the main clutch smoothly, and the bulldozer starts running. When the bulldozer is driving, the main clutch lever should be pulled to the rear, not in the semi-engaged position. Because the main clutch is half-engaged, f

  There are two types of   Excavator   according to the driving mode: internal combustion engine driven excavator and electric driven excavator. The electric excavator is mainly used in plateau hypoxia and underground mines and other flammable places. 1. According to the size, excavators can be divided into large excavators, medium excavators and small excavators. 2. According to different walking methods, excavators can be divided into  Track Excavator  and wheel excavators. Track Excavator 3. According to the different transmission methods, excavators can be divided into hydraulic excavators and mechanical excavators. Mechanical excavators are mainly used in some large mines. Hydraulic excavator generally consists of three parts: working device, upper body and lower body. According to its structure and application, it can be divided into: crawler, tire, walking, full hydraulic, semi-hydraulic, full swing, non-full swing, general, special, articulated, telescopic boom and other types.

  The purpose of carrying out regular maintenance on the excavator is to reduce the failure of the machine and prolong the service life of the machine; shorten the downtime of the machine; improve the work efficiency and reduce the operating cost. By managing fuel, lubricants, water, and air, you can reduce failures by 70%. In fact, about 70% of failures are caused by poor management.   Excavator Manufacturer   will tell you next. 1. Fuel management Different brands of diesel should be selected according to different ambient temperatures; diesel must not be mixed with impurities, lime soil and water, otherwise it will cause premature wear of the fuel pump; high paraffin and sulfur content in inferior fuel will damage the engine; daily operation After completion, the fuel tank should be filled with fuel to prevent water droplets from forming on the inner wall of the fuel tank. Before the daily operation, open the drain valve at the bottom of the fuel tank to drain water. After the engin

  Bulldozer is an earthmoving engineering machine capable of excavating, transporting and abandoning rock and soil. It is widely used in open-pit mines. For example, it is used for the construction of dumping grounds, leveling of automotive dumping grounds, accumulation of scattered ore rocks, leveling work flat plates and construction sites. It is used not only for auxiliary work, but also for main mining work. Today   Crawler Dozer Supplier   will introduce the troubleshooting of the bulldozer. Dozer 1.Main clutch slips When the main clutch of the bulldozer slips, the engine speed is normal and does not emit black smoke, and the working device works normally, but the machine is struggling to climb the hill and cannot even walk. The main clutch slip is the most common failure of  Dozer . The main reasons are: wear of the master and follower plates; the lock pin of the adjustment disk is welded; the main clutch lever is not in place; Clutch slipping is sometimes very difficult to handl

  Excavator , also known as excavator, is also an earthmoving machine that uses buckets to dig materials that are above or below the bearing surface and load them into transport vehicles or unload to the stockyard. The materials excavated by the excavator are mainly soil, coal, sediment, and pre-loose soil and rock. Judging from the development of construction machinery in recent years, the development of excavators is relatively fast. Excavators have become one of the most important construction machinery in engineering construction. The three most important parameters of an excavator: operating weight (mass), engine power and bucket capacity. Excavator Common excavator structures include power units, work units, turning mechanisms, operating mechanisms, transmission mechanisms, walking mechanisms, and auxiliary facilities. The transmission mechanism transmits the power of the engine to the hydraulic motor, hydraulic cylinder and other executive components through the hydraulic pump,
