The underground environment is harsh, damp, and contains sulfides, making the frame prone to rust. The surface of this frame is first sandblasted for rust removal, then coated with epoxy zinc-rich primer, and finally painted with polyurethane topcoat. Three layers of protection ensure a corrosion resistance level up to international C5-M standards, with no issues for 8 years of use. The operation duration can reach 15,000 hours, which is twice the industry average. The welding process is meticulous; laser cutting combined with robot welding ensures a 99.8% qualified weld rate, with virtually no cases of false welding or missed welding. Key parts use maintenance-free bearings and Dacromet coating bolts, eliminating the need to constantly apply oil and reducing the risk of rusting. This saves a lot of maintenance efforts.
There is also a thoughtful design. The frame is equipped with many quick-connect hydraulic and electrical interfaces. Automatic fire suppression systems, lighting equipment, and even 360-degree surround-view cameras can be installed. In one mine, a surround-view camera was added, reducing the blind area by 70% and enhancing safety. The front axle connection uses a swing bracket, allowing the front axle to swing laterally when traveling over uneven roads. The four wheels can all touch the ground, preventing skidding. Once in a coal mine inclined shaft, the vehicle ran at full capacity for 8 hours without any deformation or loss of power.
For the mine, this frame is truly cost-effective. It is 30% cheaper than imported ones, yet has a 50% longer lifespan. It also saves effort during operation, and with the vehicle's automatic gear shifting, the single-shift transportation capacity can increase by 20%. Over the course of a year, there are only a few maintenance occasions, and the total life cycle cost can be reduced by over 40%. Whether it's a metal mine or a coal mine, as long as it's for underground transportation, this frame can withstand the load.
Product Features
1.The articulated design is extremely flexible, capable of rotating 42 degrees, making narrow alleys easy to turn without effort;
2.Two types of steel plates are combined, which are both sturdy and lightweight, and do not shake even under heavy loads and climbing slopes;
3.The reserved interfaces are good for installing equipment, and key parts are maintenance-free, with less worry.
Tips
Every 1500 hours, remember to check the connecting pins and weld seams. If there is rust, deal with it promptly;
When installing equipment, do not randomly modify the interfaces to avoid damaging the frame's strength and affecting the hydraulic and electrical systems.
