BHD-290L

BHD-290L is our company’s latest developed drilling rig, with 400mm maximum opening diameter clamps, and the longer mast for 10.5m rotary head stroke, that can realize 10 meter vertical borehole drilling with one go, without the need of frequent coupling of the drilling rod, that further improving drilling efficiency. With detachable drilling mast, the drilling rig can be used for vertical one-go borehole drilling as well as horizontal and angular borehole drilling by detach one section of the mast. With constant drilling angle monitoring of the drilling mast the drilling rig can drill precisely to required borehole position. The operating panel can be swing in-out and up-down, making it convenient for operators to observe the borehole mouth.
