KM312 rock reinforcement roof support bolting rig
equipo de perforación con soporte de roca

Split Mountain KM312 is a rock reinforcement drill rig that installs all most common rock bolt types in combination with a screen handling arm for installation of steel wire meshes when required. Provided with a strong and reliable boom K28F, it can install from one carrier setup, several rows of rock bolts,from 1.5 m to 3 meters long. The extremely short but powerful Montabert HC50 rock drill delivers the best ratio between the rock bolt length and drift height. The rock bolting process is completely mechanized and controlled by a single operator from under a ROPS/FOPS safety cabin or FOPS safety canopy. As all the Split Mountain drill rigs based on the sturdy carrier family, the Split Mountain KM312 is designed for safety,reliablity while easy maintenance, most of the daily and routine checks are done with both feet on the ground..
