Yutong, as an advanced enterprise in the field of commercial vehicles, in addition to its passenger vehicle products with market dominance, Yutong Heavy Industries' YT series mining dump trucks have won their own advanced technology, safe and reliable performance, and efficient services since they were listed. The majority of users of all ages.
YT3621 mining dump truck is the representative product of YT series. Its unique feature lies in its core manufacturing technology of the key components of self-made dump trucks, and the large-section, high-strength, wide-body box welded frame and The more secure and comfortable overall skeleton cab has also become a unique advantage over other competitive products.
The whole vehicle brake adopts the double-pipe internal expansion type drum brake system. When braking, the entire system will act independently on the front, middle and rear axles, and it has three functions of driving, parking and emergency braking. The combined internal-breathing brake air chamber with the combination of service brake and parking brake has an engine exhaust brake function. It can act as a deceleration downhill and power deceleration through the adjustment of the exhaust brake valve . The brake drum wear is reduced and the driving safety is improved. In addition, in view of the complex environment of the mining area and the extra-wide features of the model, in order to avoid the possible danger of vehicles reversing and dumping materials, the vehicle can also be equipped with a rear-view monitoring system to effectively expand the driver's rear vision. Improve the safety and accuracy of operations.
The exterior appearance of the vehicle is strong and harmonious, and the harmony and unification of strength and beauty are achieved. The design concept of the advanced Yutong bus cab can be reversed, anti-rollover, anti-dropping, spacious interior and open vision, and the configured damping mechanism is the driver. Provides a very comfortable driving environment; the domestic first-class streamlined instrument panel, modular instrumentation , integrated heating and cooling air conditioning system, highlighting the people-oriented design concept.
In terms of power, the Yutong YT3621 mining dump truck is equipped with Weichai 12L and Yuchai high-power engines , Fast transmissions and dual-speed reduction bridges, making vehicles easier to start and stronger climbing ability of up to 35%. Mine road conditions use.
YT3621 Mine dump truck using primary structural member welded box-beam frame structure; compartment square tube as a substrate reinforcing beam car, the car-side vertical compartments beam increases, the skeletal structure of the cab. In this way , the structural strength and impact resistance of the frame, carriage and cab are improved. Under the same conditions, it is more than double the service life of the three-axle heavy truck.
The YT3621 is more than 18% wider than the three-axle heavy truck, which improves the stability of the vehicle and makes it more suitable for use in large slopes and off-highway mines. The large load capacity reduces the density of vehicles in the pit and increases Traffic safety.
In addition, the exterior appearance of the YT3621 vehicle is more novel than that of similar products. Both the robustness of mining machinery and the harmonious coordination of new trucks make it a perfect combination of exterior design of construction machinery and automobiles. The interior of the cab is luxurious and exquisite, which truly embodies the design concept of the engineering machinery saloon. Streamlined instrument panels, modular meters , and environmentally friendly flame-retardant interior materials together create a comfortable operating environment. People-oriented principles are perfectly represented in the cab .
In the process of test drive, the YT3621's demonstrated performance advantages and overall details have left a deep impression on us. As an engineering machinery product, it is not easy to have such a reality. However, compared to the classic heavy-duty trucks whose manufacturing processes are very mature, the YT3621 mining dump truck has some deficiencies in its production process. However, as a mining equipment that has only been on the market for three years, it definitely can withstand scrutiny. After all, the development process of any equipment technology is gradual and gradual. Only when it is constantly improved and continuously surpassed can it achieve a higher level of development.
Installation steps for SANY hydraulic cylinder seals
1. Preparation: Clean the working surface and seals, and check if the seals are damaged or deformed.
2. Apply lubricant: Apply a layer of lubricant to the seal and sealing groove.
3. Install the seal: Place the seal into the sealing groove, ensuring that the seal is fully embedded in the groove.
4. Install O-ring: Install the O-ring above the seal, ensuring that the O-ring is fully inserted into the groove.
5. Install the piston rod: Insert the piston rod into the seal and O-ring, ensuring that the piston rod fits tightly with the seal and O-ring.
6. Install the sealing sleeve: Place the sealing sleeve on the piston rod to ensure that it fits tightly with the piston rod.
7. Tighten the nut: Use the nut to fix the sealing sleeve on the hydraulic cylinder, ensuring that the sealing sleeve is secure.
8. Check the sealing effect: Operate the hydraulic cylinder and check if there is any leakage in the sealing element. If there is any leakage, reinstall the sealing element.
