The Cradle plate (OEM Part No. 3128314107) is a spare part compatible with Simba S7D underground drilling rigs. Manufactured from durable alloy steel, it serves as a structural component for the drilling rig cradle support assembly at the rocker mount plate position. As the core load-bearing base of the rocker mechanism, it withstands dynamic drilling loads and stabilizes the swing movement of the rocker arm. The robust alloy steel structure delivers strong anti-bending performance, precise mounting tolerance and extended service life for S7D mining equipment.
