Description
The DH-B1 is an electro-hydraulic drilling rig for drilling production boreholes in small- and medium-sized underground workings. It is designed for drilling vertical, inclined, parallel, and process boreholes and rings. It can drill boreholes with diameters ranging from 64 to 102 mm to depths of up to 38 m. 360° feed rotation, parallel drilling with a 2.0 m reach, and forward and backward tilt of the drilling module allow the rig to be used in a variety of conditions. Hydraulic thrust braces mounted on the drilling module frame ensure precise positioning and drilling. Automatic drilling and jam protection modes significantly increase the service life of the drill string. Drilling and travel are controlled from the operator platform. The articulated chassis, all-wheel drive, high ground clearance, and hydraulic steering facilitate movement on slopes and in narrow workings.
