Rotary head and front clamping assembly
Two hydraulic motors drive the rotary head, which travels along the mast through a 3,400 mm stroke. The head has 7,500 N·m output torque and 70 kN lifting force. Two clamping units sit at the front of the mast, in line with the drill string.
Crawler chassis and stabilizers
The crawler undercarriage sits beneath the main frame. Stabilizer legs with ground-contact pads are arranged around the chassis. The crawler travel speed is 0.4 km/h.
DR-180M Anchor Drilling Rig: anchor-hole drilling
The DR-180M Anchor Drilling Rig combines a hydraulic rotary head, guide mast, front clamping assembly and crawler chassis. Motor input power is 55 + 18.5 kW. The machine is used for foundation-pit anchor support and geological-hazard stabilization works.
Which drill-pipe sizes does the rig use?
Drill-pipe diameters are 73 and 89 mm. The drilling-inclination range is 0–90°, and the hole-diameter range is 150–250 mm. Rotary-head speed settings are 10, 20, 30, 35, 40, 60, 65, 70, 85, 130 and 170 rpm.
How is chassis rotation arranged?
The chassis rotation mechanism uses a slewing bearing and locating pin. The base arrangement uses manual rotation; automatic rotation is optional.
What are the transport size and weight?
Transport dimensions are 5,400 × 2,100 × 2,000 mm, and machine weight is 6,000 kg.
