XUT545 Rear Frame: Solving the Problems of Frame Cracking and High Maintenance Costs in Underground Heavy-Duty Transportation Vehicles
Industry pain points and solutions
In underground transportation operations, the rear frame of the vehicle often cracks due to heavy loads, gets damp and corroded, resulting in a short lifespan, non-universal interfaces and difficult maintenance, which have become major industry pain points. This directly leads to frequent equipment shutdowns, soaring replacement costs, and a significant decline in operation efficiency. Xiangyu Baoyuan has specifically developed the XUT545 Underground Transport Vehicle Parts rear frame exclusive accessories, in collaboration with Excavator Parts, Tower Crane Accessories, Aerial Work Vehicle Parts, and Underground Loader Parts, to form a complete engineering accessory system. This product corresponds to the Product Model: XUT545. Its dimensions are precisely set at 5765*2163*1908mm. It is constructed using a composite of Q460C and Q355B steel plates. Through structural optimization and process upgrades, it fundamentally solves the industry pain points, ensuring structural stability under heavy-load conditions, extending the service life, and reducing maintenance costs, thus laying a solid foundation for core load-bearing in underground mining transportation operations.
Technical parameters
In terms of material selection, this rear frame innovatively adopts a composite combination scheme of Q460C and Q355B steel plates - the key load-bearing areas use Q460C steel plates with a tensile strength of over 800 MPa to ensure no deformation and resistance to impact under heavy loads; the non-core stressed areas use Q355B steel plates, which not only ensure structural strength but also achieve lightweight design. Compared to the traditional single-material frame, its weight is reduced by 10%, effectively lowering the vehicle's energy consumption and enhancing the range. In terms of structure, through topological optimization, redundant materials are reduced, stress concentration points are decreased, and the bending and torsion stiffness is significantly improved. Even when subjected to dynamic load impacts for a long time, it can effectively avoid structural fatigue fractures.
Product Advantages and Value
As the core load-bearing component of the XUT545 underground transport vehicle, the core value of this rear frame lies in its ability to carry a rated load of 45 tons of minerals, waste rocks, and other materials. It is suitable for turning and climbing operations in narrow underground tunnels, and is the key to ensuring the continuity of the transportation process. Its wide range of applications covers underground mining scenarios such as metal mines and coal mines, and it needs to face extreme working conditions including high loads, high impacts, and dampness with corrosive gases. The dimensions of 5765*2163*1908mm have been precisely optimized through finite element analysis (FEA), with the length and height matching the layout of the 650L fuel tank of the entire vehicle and the maximum unloading height of 5800mm. The 2163mm width ensures the stability of the load while meeting the passage restrictions of underground tunnels, avoiding interference with the tunnel walls during operation.
Due to the high impact characteristics of underground transportation, the rear frame adopts a dual-boosting design of local thickening and reinforcing ribs at key parts such as the hinge points and suspension connections, which can effectively disperse the impact forces during material loading and driving, preventing cracking. The welding process uses automated robot welding, ensuring stable and uniform weld quality, reducing common defects such as incomplete welding and pores, and significantly enhancing the fatigue life of the frame. In the face of the humid underground environment and corrosive gases such as sulfides, the surface of the frame undergoes triple protection treatment of sandblasting rust removal + epoxy zinc-rich primer + polyurethane topcoat, with the anti-corrosion grade reaching the international C5-M standard; the key bolt connection parts are coated with Dacromet coating to prevent the threads from rusting and getting stuck, providing convenience for later maintenance.
The modular design is another significant advantage of this rear frame. Not only does it adopt standardized design for the connection interfaces with the suspension system and drive axle, facilitating quick replacement and maintenance, but it also reserves interfaces for hydraulic pipelines and electrical circuits, enabling the installation of auxiliary equipment such as water spraying devices and lighting systems, and meeting diverse operational needs. At the same time, it can be flexibly combined with different-sized cargo boxes of 10m³, 15m³, and 20m³, adjusting the transportation capacity. One vehicle can adapt to various transportation tasks, reducing the equipment investment cost for customers. The actual application data from a certain metal mine shows that this rear frame only requires routine maintenance for three consecutive years and has not suffered any structural damage. In contrast, similar products have been replaced twice due to the cracking of the frame, directly saving the customer over 200,000 yuan in costs.
With its high reliability, the rear frame has a 50% lower failure rate compared to traditional products, reducing the annual maintenance frequency to 1-2 times, significantly reducing downtime. The triple anti-corrosion treatment extends its service life to over 8 years, which is twice that of ordinary frames, and significantly reduces the replacement cost. Whether it is for underground tunnel transportation in metal mines or coal mines, or for the transfer of heavy materials, this rear frame can support efficient operations with stable performance, becoming the core product in Xiangyu Baoyuan's engineering accessory system that is suitable for extreme underground working conditions.
