DW3-180 Drilling Jumbo
Applied to mining and tunneling, such as hydro-power,railway, highway, national defense and other underground areas. Hydraulically controlled with three booms and one service platform. Drill speed could reach 0.8-5 m/min and diesel engine drive the tyre-carrier traveling. Applied max.tunnel section is 17.4mX13.3m (WxH), and the Max. Tramming speed is 16 Km/h.It’s computer control system can realize jumbo automatic positioning and drilling boom automatic positioning, Available with a variety of tunneling machines to suit customer requirements.
Standard features
HYDRAULIC BOOM
• Hydraulic boom with double tripod suspension for accurate hydraulic parallel holding in all directions; Direct, fast, Easy operation, good accuracy and accurate positioning between holes;
• Telescopic boom make up of the angle when drilling the hole of bottom and top, thus no blind angle left
