What makes a good minecart? Everyone has a ruler in their hearts. Some people look at workmanship, some look at price, some look at performance, but more people look at safety first. Transportation is one of the important links in open-pit mining. With the double excellent results of Dora's fast running and the heavy load, the industry has long had high-level students. "Safety + reliability, safety + quality, safety + service" such XCMG three-bridge rigid mining vehicles have not only become the mainstream of mine transportation, but also become synonymous with current safety mining vehicles.

As the name suggests, the Three Bridges has one more set of bridge structures than the Double Bridges. Traditional wide-body vehicles are transformed on the basis of road transport vehicles. In terms of performance and return on investment, it does have the advantage of being "short, flat and fast", but this deviates from the industry requirements for large-scale and intelligent mining equipment. XCMG resolutely gave up such shortcuts and sought another solution for wide-body vehicles, so a large-tonnage three-axle rigid mining vehicle known for its safety was born in the world.

95% attendance based on full load of 20 hours per day

The inherent safety gene is the prerequisite for reliable quality. In the initial stage of product design, engineers will define the performance of the vehicle one by one according to this standard. From development to delivery, the whole process will not deviate from it, let alone weaken it. In the process of transportation, depending on the vehicle itself, driving level and on-site road conditions, the phenomenon of overturning will occur. How to prevent this problem, XCMG took the lead in giving a solution. The first three-axle rigid mining car adopts a full oil-pneumatic suspension system (replacing the traditional leaf spring structure), and the carrying capacity is increased by 60%. The front axle is an independent suspension, and the left and right wheels do not affect each other, which reduces the wear and tear of tire sideslip, and the body is not easy to tilt when crossing obstacles.

6 years of super long service comes from the precision polishing of every detail

The three-bridge rigid mine car adopts the anti-fatigue optimization technology of the fully welded frame. The beam and longitudinal beam of the frame form a closed structure; the longitudinal beam is a box-section structure, and the beam is in the form of a torsion-resistant tube, which can eliminate the source of bending and cracking stress concentration; the frame is made of high-quality low-alloy high-strength steel, and the important welds are 100 %After ultrasonic flaw detection, the key welds are fully penetrated and welded, which fully guarantees the reliability of the frame.

The cargo box adopts a lightweight design, and the bottom and side panels of the cargo box are made of high-light wear-resistant steel, which is resistant to cracking, deformation, and expansion. The side panels and front panel of the cargo box are reinforced with thick ribs. The tires are large-diameter engineering radial engineering tires to ensure sufficient ground adhesion, greater traction for the whole machine, and a comprehensive service life of more than 8 years.

Anchor technological innovation and lead the industry revolution. XCMG Mining Machinery actively promotes the reform of open-pit mining technology and equipment, and accelerates the development and application of safe, efficient, intelligent and environmentally friendly mining vehicles. It is said that the word "safety" is worth a thousand gold, but what I want to say is that the word "XCMG" is also worth a thousand gold.Editor/Ma Xue
