The Cradle plate (OEM Part No. 3128314094) is a spare part compatible with Simba S7D underground drilling rigs. Manufactured from durable alloy steel, it acts as a structural component for the drilling rig cradle support assembly at the rocker mount plate position. As a core load-bearing base of the rig rocker mechanism, it bears continuous dynamic loads during drilling operations and maintains stable swing movement of the rocker arm. Its thickened alloy steel design offers high bending resistance, accurate mounting tolerance and long service life for S7D mining equipment.
