The roller frame is fabricated by splicing and welding high-strength alloy steel plates. With an integrally reinforced main beam design, it features high overall rigidity and outstanding torsion resistance and load-bearing capacity.Key stress-bearing positions are thickened and reinforced with precise and firm welding. Stress relief treatment effectively prevents deformation and cracking.It is vibration-resistant, fatigue-resistant, corrosion-proof and durable, adapting to heavy-duty harsh conditions such as subgrade construction and mine roads, and provides stable support for the steel wheel, cab and power system of the whole roller.
