The 3 heavy-duty axles from FUWA or BPW ensure stability and reliability, while mechanical or air suspension options provide smooth performance on rough terrain. Combined with advanced automatic welding and shot peening processes, this trailer offers excellent structural strength and reduced maintenance costs.
