Topcon developed machine-control kits for Komatsu’s D51 slant-nose dozer model with customized mounting brackets, cables, hydraulic and machine-control components to simplify installation and save time in the field. To minimize cable routing, a new junction box has been designed for Millimeter GPS cable connection, single and dual GPS connectors, slope and laser/sonic connectors. The kits make use of access holes throughout the machine for easy cable routing. A low control-box bracket allows better viewing. There are preset locations identified for mounting Topcon’s machine receiver, bolt-on mounts for the pilot-valve bracket, and a bolt-on slope-sensor bracket with anti-vibration mount.
