458 Multi-functional Crawler-type Deep Hole DTH Drilling rig
458 Internal combustion (458D electric) crawler-type deep hole drill rig adopts diesel motor (electric motor). Hydraulic oil pump unit offers power to hydraulic motor moving, turn around, propulsion and lifting, and angle orientation of oil cylinder, etc. When drill is working, only the down-hole hammer consumes the compressed air.
The Drill is used for water well, geothermic air-conditioner drilling operation and various stonework blast hole operation; the drill can also realize the process such as breast wall drilling with casing following, conduct drilling grouting hole of the hydropower cofferdam, grouting hole for dyke seepage control and grouting hole for base enforcement and anchor hole, etc.
