Product Overview
The Heavy Mining Truck Rear Crossmember is a critical load-bearing structural component of mining dump trucks, rigid mining trucks, and ultra-heavy engineering transport vehicles.
Installed at the rear section of the chassis, it connects the left and right longitudinal beams, and supports the suspension system, dump body structure, and rear assemblies. It serves as a key structural node for load transfer and chassis reinforcement.
Mining vehicles operate under extreme conditions involving heavy loads, severe impact, vibration, and continuous harsh environments. The rear crossmember must withstand dynamic loads ranging from tens to over one hundred tons, requiring exceptional strength, toughness, weldability, and fatigue resistance.
With over 40 years of heavy-duty engineering casting experience, Sangroove (Jiangsu) Machinery Co., Ltd. specializes in manufacturing mining truck rear crossmembers, gantry beams, subframe brackets, and large structural castings for global mining equipment OEM customers.
