44 E&MJ; • OCTOBER 2017 www.e-mj.com NORDIC TECHNOLOGY 2017 Doofor Develops Drill Feed Kit For years Nokia, Finland-based Doofor has supplied the min- ing business with reliable rock drills, or drifters and supported them with service and spare parts. "Our philosophy is to offer the highest technical quality in the drilling industry," said Kalle Kuusento, managing director, Doofor. "Our drills are recognized worldwide as powerful, reliable and durable." Earlier this year, the company introduced a component kit for a hydraulic rock-drill feed system. With the kit, drilling profes- sionals can build custom rock-drill feed systems quickly with a relatively small investment and a little effort. The component kit includes a Doofor hydraulic rock drill, a hydraulic valve block, a feed profile of anodized aluminum, carriage plate for the rock drill with sliders, drill steel guides, drill steel retainer, a durable feed chain, hydraulic feed motor and guarding for safety, as well as all other necessary casings. "Instead of developing a feed system from scratch, our cus- tomers can purchase these kits," Kuusento said. "We do not make drilling systems. We only supply drifters and this is pure- ly an effort to support customers." Kuusento said the system has been well-received. They have received many inquiries from South Africa, North America and Asia. "As a company, we are innovative and development driven," Kuusento said. "We stand for the highest level of endurance and functionality. Our products are robust, easy to fit in various solu- tions and built to perform in difficult conditions." Doofor is current- ly developing new drilling technology for larger (25 kw) systems. Alimak Adds Traction Elevators Alimak Hek, a leader in rack-and-pinion elevators, recently launched a new series of traction elevators. The company, which is based in Skellefteå, Sweden, now offers one of the world's most comprehensive industrial elevator product portfolio with both traction and rack-and-pinion drive technology and a wide range of car sizes and capacities. These systems have niche applications as raise climbers underground. The new Alimak traction elevator series, Alimak TR-H, is de- signed and built to perform in the world's harshest environments. The elevator will improve operational efficiency, give superior HSE performance and reduce maintenance costs in any industri- al application. With surface treatment corrosion classification up to C5 and ingress protection rating up to IP65, the new elevators are made for the toughest environments on the planet. "The expansion will ensure that Alimak Hek engineers give the best advice to choose the perfect elevator technology for the application," said Andreas Magnusson, marketing communica- tions manager, Alimak Hek. With more than 22,000 rack-and-pinion elevator installa- tions, the company's in-house engineering department has vast experience. "Many of these elevators have unique applications, but they are all based on standard design parameters and sub- ject to a strict quality assurance management," Magnusson said The modular design of the three new traction elevator series Alimak TR, TR-H and TR-H Ex provides several different car siz- es within the standard range — meeting just about every trans- port need imaginable from 300 kg to 5,000 kg (660–11,020 lb). Additional sizes and specifications can be provided. The robust elevator cars are made from durable materials in- cluding stainless steel, aluminum, or painted steel with bumper rails and diamond plate flooring together with other options. El- evator doors can be manual or heavy-duty automatic with fire rated doors as an option. Robust industrial design gives the new elevators the ability to handle the toughest working environ- ments from non-hazardous areas to extreme environments with temperatures of 0°C to +50°C. Normet Sets New Standards for Ancillary Support During June, Normet rolled out some new equipment at the World Tunneling Conference (WTC), which was held in Bergen, Norway. The Iisalmi, Finland-based company said this new of- The Doofor kit includes a drifter, feed profile and everything else needed to build a drilling system. The new traction drives can handle loads up to 5,000 kg.
