● Power system: adopts 4100 engine, with large torque, strong power, and durable construction; low failure rate, simple maintenance, adapt to harsh working conditions such as high temperature and humidity underground. In recent years, domestically-made engines have been mature and stable in technology and more cost-effective. The equipment working environment in the tunnel is bad (humidity, dust, etc.), labor intensity is high (8-20 hours/day), and untimely maintenance and other factors can easily cause early engine wear, black smoke, and power after one year. Problems such as descent need to be overhauled. Imported engine maintenance costs are high, the cost of a major repair ranges from 20,000 to 20,000 yuan, and some parts need to be purchased from abroad, and the waiting time is long; while the domestic engine assembly price is about 20,000 yuan, and the parts are versatile and the price is lower, Easier to purchase.
● Transmission system: 265 type hydraulic torque converter power shift transmission is adopted, and it is matched with a large-speed ratio mining machinery special caliper disc brake drive axle. The input torque is large, the transmission efficiency is high, the work is stable, and the low speed and large torque are realized. The first-stage shovel loading is more powerful, the bucket is easy to fill, and the work efficiency is high. Compared with imported variable pumps and variable motors, domestic hydraulic torque converters and power shift transmissions have the following advantages: The engine does not need to work at a high speed all the time. It can independently adjust the throttle of the engine under full load and no-load conditions, autonomously control the working load of the whole machine, and save fuel. However, the equipment that uses variable pumps and variable motors works all the time. Maintain a high speed, no matter full load or no-load fuel consumption is relatively large, and the noise is large.
● Working system: using pilot control to make the work easier and more efficient. The use of dual steering cylinders for steering is more stable and reliable and has a lower failure rate than the single steering cylinders used by other manufacturers.
● Electrical system: It is designed to be waterproof and moisture-proof to adapt to wet conditions in underground mines.
● Brake system: The service brake is air-capped oil caliper disc brake, and the parking brake is spring brake and hydraulic release, which makes the brake safe and reliable. For equipment with variable motor, only one brake at the input end of the transfer case is used for braking. The main brake is to use the hydraulic circuit between the pump and the motor to block the brake. The impact on the pump and the motor is large, and the hydraulic pipeline is prone to occur. Rupture, causing the risk of brake failure.
● Exhaust gas purification system: adopts water filtration device + oxidation catalyst to achieve two-stage filtration. Exhaust gas is discharged in the form of water mist and quickly settles to the ground, which greatly reduces air pollution and protects the roadway environment and the physical and mental health of the driver.
● The engine air intake adopts an oil-bath air filter, which replaces the ordinary paper air filter (the paper filter element will be deformed and blocked due to the moisture in the intake air and lose the filtering effect), and there is no need to replace the filter element.
● The steel frame of the vehicle is thickened, and the rigidity of the vehicle is enhanced. The bucket blade is made of high-strength alloy steel, which is wear-resistant and shear-resistant. The V-shaped structure reduces the resistance of shoveling and has a longer service life.
● Smooth wear-resistant and puncture-resistant tires are used, and four tire protection chains are used to make the tires have a longer service life.
● Strong climbing ability, full load maximum climbing 16°, with the assistance of hoist, it can be used for excavation of slopes within 28°, instead of slagging machine.
● The rear frame of the machine can be disassembled into 5 parts, which is convenient for going down the well.
● The machine is compact in structure and easy to operate. It can perform integrated operations of shoveling, loading, transporting and unloading. It has high work efficiency and is suitable for mining and digging of roadways, as well as auxiliary operations such as construction and leveling of work sites and roads, and material transportation.
