Nordberg (UK) Ltd have introduced a new drill rig from Sandvik Mining and Construction group company BPI. The 115 MC has been designed as a compact workhorse for small-to-medium quarries and construction sites. It is powered by a fuel-efficient, water-cooled Deutz diesel engine that develops 130kW at 2,300 rev/min. Driving through a new drive motor and two-speed transmission to the steel-tracked crawler undercarriage, the engine meets all current emissions regulations and provides the 12-tonne rig with a tramming speed of 3km/h.
The unit features a well appointed ROPS/FOPS operator’s cab with a fully adjustable suspension seat, as well as air-conditioning and heating as standard. Large windows provide improved visibility for easy drill bit positioning and enhanced site safety, while ergonomic joystick controls and advanced monitoring and control systems make the unit easy to operate. The control panel incorporates an electronic angle indicator that allows precise adjustment of the drill angle for improved blasting results.
The drilling equipment utilizes drill tubes of between 70mm and 89mm diameter to produce drill holes of 90–127mm. The drill feed provides a robust breaking device with changeable wear jaws. The rotation motor on the feed is advanced by a feed motor with a planetary transmission and integrated hydraulic motor. A swing head allows the unit to drill holes 90° left or right of centre.
A telescopic boom is fitted as standard, with an articulated boom available as an option. Other optional equipment includes: a drill-tube magazine for six 89mm diameter drill tubes or seven 70mm drill tubes; a fuel-save system; foam injection for flushing applications; and an angle indicator with depth meter and data-storage facility.
