Klemm Bohrtechnik - part of the Bauer Group - introduced the KR 806-4GM anchor drilling rig for overburden drilling with an automatic MAG 6.1 drum magazine for double-head drilling. The manufacturer said the goal with this machine was to be below the weight class of the KR 807-7 series; it has a net weight of 21.9 tonnes (without pipes) and allows for a maximum load of 1,100 kilograms (kg). The maximum diameter for the casings is 178 millimetres (mm) and the usable length of the pipe pairs is 3,000mm. Both plain drill rods and drilling augers can be used as internal rods, the manufacturer explains. The upgraded MAG 6.1 drum magazine has a rotatable drum, which ensures that the equipment operator always has a good view of the drill rod to be positioned. It also has a newly developed kinematics system, Klemm said.
