The bulldozer can separately perform excavation, earth moving and unloading work. It has the characteristics of flexible operation, convenient rotation, small working face and fast driving speed. So how is  Hydrostatic Bulldozer   energy-saving technology applied? 1. The hydraulic system of the working device adopts differential overflow technology. In this way, when the working device reversing valve is in the small opening throttle speed regulation process, the excess oil supply of the oil pump can be returned to the oil tank directly from the differential pressure valve without passing through the safety valve, so that the system pressure in the speed regulation process is only higher than the working pressure. The high value is ΔP, so as to reduce the hydraulic power loss and reduce the oil temperature. 2. Engine and working device hydraulic system and transmission system adopt full power matching technology. The engine can automatically adjust the power output to the transmis

When choosing  Bulldozer For Port Construction , users should not only consider how to purchase from a technical point of view, but also pay attention to the cost performance of the bulldozer. If only for a project, select a product with high performance and high cost, and ignore the subsequent use cost. Not only is the waste of money, but it also does not fully utilize the efficiency of the machine and cause unnecessary waste. This will bring greater leisure time to the management of reducing construction costs for any enterprise that carries out engineering construction. In addition, for the user, it is necessary to consider the manufacturer's technical maintenance and repair service and the supply of accessories, whether it can provide timely service and convenient and quick supply of spare parts, whether it can solve the construction machine failure in the shortest time, fully guarantee the project. schedule. These are the most important issues for the user. We are  Crawler

Safety production is the premise of work, so be sure to do the daily inspection and maintenance of  Track Loader . It is necessary to check the machine before and after the work every day. To ensure the safety of the work. The inspection contents are as follows: 1. Check whether the work lights, indicators, etc. are damaged, and whether the lines, pipes of electricity, gas and oil are aging or damaged. 2. Check the dust of the engine air filter to affect the air intake effect. 3. Check whether the connecting bolts of the front and rear drive shafts are loose or loose, and the locking force is 530N.M. 4. Check if the connecting bolts such as the pins are loose. 5. Check for oil leakage, water leakage, leakage, and air leakage. 6, check the water level, transmission oil level, hydraulic oil level, brake oil level. 7. Add grease to each nozzle. 8. Check the brake pad wear. 9. Check the wear of the bucket blade and the tooth. When the blade wears 10cm and the tooth wear

According to the actual work experience of the  Track Loader , the following procedures can be used for diagnosis and elimination: (1) Check the servo pressure. Connect the 60 bar pressure gauge to the servo pressure pressure tap. If the pressure is 21 bar, it will be normal. Otherwise, the servo pressure valve should be adjusted. If it cannot be adjusted, check the servo pump. (2) Check the pressure difference of the throttle valve, connect two 60 bar pressure gauges on the pressure measuring port before and after the throttle valve, and measure the two pairs of pressure values at high speed and 1400 rpm, such as the pressure difference is 4 ± 0.4, and It is normal that the error of the two speeds does not exceed 0.4 bar. Otherwise, the right-angle link mechanism should be adjusted to make the value normal; if it cannot be adjusted, the throttle valve is faulty, and the throttle valve is repaired or replaced. (4) Check the operation safety valve, if it is not normal, repair and

The development of  Crawler Dozer  product types must meet the work adaptability of different working conditions, and must maintain the maximum component versatility (or interchangeability) with the basic model, which will bring convenience to the users.  The crawler bulldozer is mainly composed of an engine, a transmission system, a working device, an electric part, a cab and a hood. Among them, mechanical and hydraulic transmission systems include hydraulic torque converters, coupling assemblies, planetary gear-type power shift transmissions, central transmissions, steering clutches and steering brakes, final drives and travel systems. The power output mechanism drives the working pump, the variable speed torque hydraulic system variable speed pump and the steering brake hydraulic system steering pump in the hydraulic system of the working device by means of gear transmission and spline connection; the sprocket represents the final transmission mechanism of the secondary spur gear

The  Track Bulldozer   has the greatest influence on the transmission oil temperature due to the external resistance and the maximum output torque during the shovel operation. If the small throttle is used for a long time to operate the torque converter in the inefficient zone, the transmission oil temperature will rise. If the large throttle is used during frequent shifting, it will cause severe impact on the machine and increase the temperature of the transmission oil. To this end, the operator should reasonably control the amount of bulldozer and the timing of the blade lifting and lowering. The soil feeding distance should not be too long, so as to prevent the use of small throttle for a long time. We are  Track Bulldozer Supplier , specializing in the production of machinery and equipment, welcome to consult and order.

The  Wheel Loader  is an earth-rock construction machine widely used in road, railway, construction, hydropower, port, mining and other construction projects. It is mainly used for shovel loading bulk materials such as soil, sand, lime, coal, etc. Different auxiliary work devices can be used for loading and unloading of bulldozers, lifting and other materials such as wood. In the construction of roads, especially in high-grade roads.   Track Loader  is used for the filling and excavation of subgrade works, aggregates and loading of cement concrete yards. In addition, you can carry out operations such as pushing soil, leveling the ground, and pulling other machinery. Because the loader has the advantages of fast operation speed, high efficiency, good maneuverability and light operation, it has become one of the main types of earth and stone construction in engineering construction.

Wheel excavators are ideal for working in flat areas and are easy to transport. Wheel excavators can travel on the road, eliminating the need for many trailers and without damaging the road. Now let's briefly introduce the places that need to be paid attention to when the wheeled excavator is operated. 1. Before driving, place the bucket on the frame, insert the turntable fixing pin, close the hydraulic leg, and check if the steering wheel, brake and lighting are good. 2. When turning, you should change to the low gear in advance and turn on the turn signal. When turning slowly, you should turn early and slow down, and you won't be able to play back.  3. Pay attention to the shift operation. We are  Wheel Excavator China Supplier   and  Track Bulldozer Manufacturer , you can buy your own excavator according to your needs. This is our factory and you are welcome to visit.
