44 E&MJ; • JANUARY 2016 E Q U I P M E N T G A L L E R Y www.e-mj.com Normet has launched its new M- and L- Series underground mining and tunneling equipment line with European Stage IV/U.S. EPA Tier 4 Final (4F) power train technology, featuring Cummins engines and equipped with an engine brake, lock- able turbine and automatic gear selector. The new power and drivetrain concept, according to Normet, provides the lowest possible emissions, higher speed in flat and inclined tunnels, superior driving and service ergonomics, and better driving properties on declines. Tier 4F technology is available for all Spraymec concrete sprayers, Utimec concrete transporters, Charmec explosive chargers, Himec/Utilift lifting and installation units, and Utimec, Variomec and Multimec material, person- nel logistics and service vehicles on M- Series (10 t) and L-Series (16 t) carriers. The new M-Series offering is equipped with a Cummins QSB4.5 119-kW engine and the L-Series with a Cummins QSB6.7 168-kW engine. The exhaust after-treat- ment system uses exhaust gas recircula- tion (EGR), selective catalytic reduction (SCR) and diesel oxidation catalyst (DOC) technology with diesel exhaust fluid (DEF urea). The new engine technology requires the use of ultra-low sulphur diesel (ULSD). Tier 4F engines produce fewer emis- sions and provide better fuel economy than older generation engines, said Normet, not- ing that emissions from one Tier 3 machine equal those from 10 Tier 4F machines. Tier 4F engines also consume 8% less fuel than Tier 3 engines. All the new equipment will be fitted with an engine brake and lockable turbine as stan- dard in a Dana 24000 transmission for the M-Series and a Dana 32000 transmission for the L-Series. The engine brake provides fully controlled operations in a decline tunnel, eliminating any need to apply the service brake. In inclined tunnels, the lockup turbine transfers the power from the engine to the wheels with the highest possible efficiency and offers 2 km/h higher speed. The automatic gear selector uses three gears for the MC, MF and LC Series, and four gears for LF Series transportation vehicles like Utimec, Multimec and Variomec con- crete transporters, dumpers and service vehi- cles. The LF Series' maximum speed is up 77% from 18 km/h for the older offering to 32 km/h for the new offering. www.normet.com Versatile Belt Trainer Quickly Corrects Mistracking Flexco's first reversing belt trainer, the PT Pro, uses the company's patented pivot and tilt design, is capable of tracking single- direction and reversing belts and is available in standard- and heavy-duty options. Unique, tapered rollers activate the trainer movement, eliminating the need for sensor rollers. The unit reacts to belt misalignment and compensates instantly, ensuring that the belt stays away from the structure and material stays on the belt—the pivot on the trainer influences the direction, while the tilting action increases the tension on the mistracked side, resulting in two forces that quickly move the belt back to center. The PT Pro can be used for belts that are mistrack- ing to one side or wandering to both sides. The trainer features simple brackets for quick and easy installation. An adjustment screw fine-tunes the trainer for optimal per- formance. Unlike other trainers, the entire PT Pro unit does not have to be replaced when the roll has worn. Rolls are available for reorder and replacement. Ideal for medi- um- and heavy-duty applications, the train- er performs in both wet and dry conditions and is recommended for use in underground mining and surface mining, aggregate and bulk materials handling applications. www.flexco.com Rotary Drill Bits Provide Longer Service Life Sandvik's new RR221 bit series is the latest addition to the company's rotary blasthole bit line. Developed to meet the need for a more productive and longer-lasting rotary bit, the new model represents a more resilient bit designed to extend bearing hours—sav- ing customers money, reducing safety risks and boosting productivity. The RR221 series employs a patented, modularized air bearing Underground Utility Equipment Line has Tier 4F Engine Technology
