DRILL & BLAST
The Crossover is part of a new line of soil investigation rig from TMG
and weighs 227kg. David Jonsson, product portfolio manager, says, “T e RD 14S is intended for customers that prioritise reliability and ease of maintenance rather than peak performance; for smaller operations where cost is critical this would be an optimum rock drill of choice.” To simplify the design and maintenance, the company has reduced the number of parts, using a single internal dampener and a two piece body.
Italian company Massenza has launched the M13, an upgrade of the M12. T e new machine is more
powerful, with a 70hp engine, giving a drill speed of up to 712rpm. Torque is up to 7845Nm. Despite this it is slightly smaller and lighter, and at 2,700kg, is designed to be mounted on a smaller trailer.
A safety cage is off ered, depending on local legislation, and remote
control is available. Drilling methods include direct circulation, SPT, down the hole hammer drilling, coring and augering. ●
S
andvik has added to its DD2710 single-
boom hard rock drill line with the launch of the DS2710 rock support drill and the DL2710 and DL2720 longhole drills. The new design, which is mounted on a four- wheel-drive undercarrier, features a FOPS-certifi ed safety canopy, LED lights and an automated shutdown system in case of emergency
