Robust & compact top head with large torque and strong percussion, which developed by Bealong independently, is suitable to use in diverse geological stratum. Crawler with large tractive force, which manufactured by TDS, gives smooth and reliable ride to drill rig at diverse road conditions. The efficiency of the hydraulic system of the drill rig improves dramatically through applying load sensing technology. The drill mast with large swing & tilt angles makes the drill rig more suitable for operating efficiently at various working conditions. Swingably & integrated operation panel of the drill rig gives drillers easier and more flexible operation.
