  The front of the bulldozer is a bulldozer blade. Under the control of the driver, the blade is put down and the blade is cut into the soil. The power of the bulldozer when it is advancing can complete the cutting and pushing of the soil. Bulldozer is a self-propelled construction machinery suitable for short distance bulldozing. Because of its simple structure, flexible maneuverability, ability to adapt to a variety of operations and high productivity, it has been widely used in infrastructure construction. It is the most widely used construction machinery.   Bulldozers are widely used in earth and stone engineering in construction, highways, railways, airports, ports, mining, agriculture, water conservancy, forestry and national defense construction. The bulldozer can shovel and transport soil as follows: Generally, soil and other loose materials are shoveled within a distance of 100 meters. It is used to build roadbed, excavate cuttings, and pile up gravel. Filling: Backfilling tre

  Do you know how to operate a  Track Bulldozer ? When shifting into gear, first, push the throttle handle to the low-speed idle position, and then push the main clutch lever to the front to disengage the main clutch. Due to the small break in the main clutch, the power input shaft of the transmission stops rotating. At this time, you can move the shift lever to the desired gear correctly, and then put the forward and backward levers to the forward or backward position (when the bulldozer moves forward, pull them forward and backward levers backward, and when backward, push forward). After the gear is engaged, pull the throttle handle backward to increase the engine speed, and connect the main clutch smoothly, and the bulldozer starts to run. When the  Dozer  is driving, the main clutch lever should be pulled to the rear, and should not be placed in the semi-engaged position. Because the main clutch half-engaged will increase friction plate wear. Bulldozer transmissions generally have

  As the most common machinery in engineering, excavator can work in various environmental situations, so what should we pay attention to under these working conditions? Let the   Excavator Manufacturer   tell you below. 1. Excavator works in cold winter When the temperature is particularly low, the viscosity of various oils increases and it becomes difficult to start the engine, and if the coolant freezes, it will damage the engine and the water tank. 1) Switch to diesel, lubricating oil and hydraulic oil with low viscosity. 2) When using the machine in cold winter, the proportion of antifreeze added to the cooling system should be the proportion at the lowest temperature. The use of methanol, ethanol or propanol-based antifreeze is prohibited. Whether it is used alone or mixed with antifreeze, we must avoid the use of anti-leakage agent. Do not mix one antifreeze with another antifreeze of a different brand. For permanent antifreeze, there is no need to replace it within one year. If

  As the main customers of  Excavators   are located in rural and urban areas across the country, excavators work efficiently and are highly mobile. Most of them have their trailers, situated between the mountains and the jungle. In the construction of excavators, safety is always the number one issue. What are the safety requirements and precautions for driving an excavator? How to operate the excavator safely in different terrains? Next, we follow the  Excavator manufacturer   To understand. First of all, the trailer should not be too high, and it cannot be wiped easily.  High-Quality Excavator  tires are usually 750-825. Secondly, the brake must be air brake, preferably water jet brake, long-term downhill brake, the brake is easy to soften, and even the accident that the car hits the cliff is caused by oil brake. Then, it is recommended to stop the air brake when stopping. If there is no air brake, when the excavator moves up and down, the wheels must be placed on the stone. It is n

  Excavators encounter a variety of conditions in their work, of which steep slopes are the most common, but how can the excavator quickly and safely go up and down various slopes?   Excavator Manufacturer   summarizes the following points for everyone through years of production experience. First, uphill and downhill 1) When driving down a steep slope, use a walking joystick and a throttle joystick to keep the driving speed low. When driving upward or downward on slopes exceeding 15 degrees, the angle between the arm and the boom should be 90 ~ 110 degrees, the distance from the back of the bucket to the ground is 20 ~ 30cm, and the engine speed is reduced. 2) If braking is required when going downhill, put the walking joystick in the neutral position so that the brake will automatically work. 3) When walking on an uphill slope, if the track shoe slips, in addition to relying on the driving force of the track shoe to drive uphill, the pulling force of the stick should be used to help
