Purpose- built to aggressively engage the material bank, M-Series screener crusher buckets enable the load to be crushed and pro- cessed in less than 60 seconds, providing a processing capacity of up to 650 t/h. There are six M-Series models, each with the abil- ity to produce up to four fragment sizes and fit 30- to 90-ton-class wheel loaders and 50- to 160-ton-class excavators. The patented rear-mounted drum and bearing design uses three or four rotating crushing drums that are powered by a hydraulic motor. The hydraulically operated hinged mount plate on the wheel loader models enables an M-Series screener crusher attachment to also be used as a loading bucket with normal load-and-carry characteristics. In- stallation of the M-Series screener crusher includes a wired control panel located inside the carrier's cab, which monitors and dis- plays key performance data including hydraulics, temperature and bucket angle, as well as providing a link for real-time ALLU after-sales service. As with standard buck- ets, the M-Series screener crusher is designed with changeable wear parts. www.allumining.net Industrial Shop Hoppers Have Durability, Safety Features Self-dumping material handling hoppers fabricated by Iron Bull Manufacturing are equipped with a proprietary Positive Alignment System featuring a tapered slide box with expanded clearance angles for fast, accurate entry of forktruck forks into the hopper base channels. Engineered for rugged, long-term service, the hoppers are strengthened by wrap-around welded lips on back corners, sides that extend below hopper bottoms, full-length channel bases, and gussets welded into front corners. A dual safety lock package includes manual flip lock and retaining chain that hooks on to the hoppers, stabilizing loads to pre- vent accidental sliding or spillage. An optional "Dump from Seat" latch rope (shown in the accompanying photo) pro- vides added safety, allowing operators to remain seated while releasing loads rather than having to dismount the forktruck to manually discharge them. Iron Bull pro- duces three series of hoppers—Economy Bull, Baby Bull and Big Bull—with weight capacities ranging from 1,500 lb to 6,000 lb and 1/3- to 2-1/2-yd 3 capacities. Hoppers customized to customer specifica- tions also are available. Hopper safety decals are in English and Spanish, as are operating instructions. www.ibullmarketing.com Mine-duty Cable Couplers Install Faster, Perform Better TE Connectivity announced the availability of its high-performance Raychem mining couplers, designed for easier and faster installation and better performance. These couplers feature range-taking, IP68H-rated cable entry seals that can be visually inspected, and range-taking shear bolt connectors requiring just two sizes to cover No. 6 AWG to 500 MCM cables. Shear heads ensure that the correct torque is applied to each bolt for optimal contact force. Raychem couplers feature internal phase-to-phase ground barriers to avoid high-energy, potentially explosive phase-to- phase faults. Enhanced electrical perform- ance is achieved with high-strength, impact-resistant insulators with Raychem proprietary ZnO stress grading termina- EMJ_pg88-93_EMJ_pg88-93 7/1/14 2:39 PM Page 90
