NORDIC TECHNOLOGY 2018 OCTOBER 2018 • E&MJ 37 nomics and productivity. One of our cus- tomers measures whole-body vibration and Jama makes one of the few machines that miners can operate for eight hours with- out exceeding whole-body vibration limits. We have developed an advanced vibration dampening mechanism for the scalers." "Based on the same chassis, we have also developed a shotcrete rig, the CSU 8000 and a secondary scaling unit, the RBU 8000, for Kiruna's sublevel caving operations. With an 11-m reach, the oper- ators can sit at a safe distance and work." The machine has a three-piece, extend- able boom with a rotation device and a 2-prong ripping tool. "Taking the modern, standard chassis at step further, we are making several dif- ferent machines today, such as different utility vehicles and charging units," Nor- berg said. These products are all placed on a standardized truck or dumper chassis. "We add the equipment to the chassis and deliver a fully tested, certified machine," Norberg said. "The machines have differ- ent stabilization systems, such as outrig- gers, depending on the application." Jama has also developed a rescue hoist- ing system. "You have to be extremely fit to climb a 300-m shaft," Norberg said. "Our mobile rescue hoist could be used to res- cue miners from smaller diameter ventila- tion shafts." The compact system can be carried around the site by a wheel loader. For both underground and surface ap- plications, Jama has developed drill rig for a wheel loader that can be used to drill and shoot boulders. More recently, Jama signed an agreement with Epiroc to sup- ply grouting machines. "This is a Craelius legacy project," Norberg said. "Epiroc se- lected Jama as a partner to build these units for them. Jama assembles, tests and delivers the units."
