Pneumatic Drill Rig HQZ220L
On steel tracks and with 58 kW of rated output, this rig drills down to 220 m. Hole diameters run from 130 to 254 mm, lifting capacity is 15 t.
Two hydraulic motors drive the rotary head. A quick-shift valve regulates the speed steplessly, and torque reaches 4000 to 4600 N·m. The machine is built for hard ground such as rock and concrete.
Tower and feed match the smaller rig in the series: a tower height of 3 m and a feed of 3.6 m in one pass. Total weight has stayed at 4500 kg as well, while the overall length grew to 3800 mm.
