Silver Mine Gets Electric LHDs

Hecla’s Lucky Friday mine deployed two Artisan Vehicle Systems 153 haulers, which are powered by lithium batteries. The mine is seeking to resolve ventilation and cooling issues, Hecla reported.
The 153 was covered in the December E&MJ. Artisan reportedly designed the 153 around the electric powertrain, battery, and advanced operator control system. The 153 is smaller than a comparable diesel loader, but has 300% of the power, Artisan reported. With 3 metric tons (mt) of tramming capacity, the LHD’s total power is 214 kilowatts and tractive effort is 75 kilonewtons. The powertrain motor’s peak power is 127 kilowatts (kW) or 170 horsepower. Its peak torque is 695 newton meters, or 513 foot pounds. It is powered by a 600 volt DC, 88 kW-hour lithium iron phosphate battery. The bucket is 1.2 cubic meters (m), or 1.5 cubic yards. Lift breakout force is 4,899 kilograms (kg) (10,888 pound force [lbf]); tilt breakout force is 7,031 kg (15,500 lbf). Total operating weight is 9.5 mt.

Sealed Ultra-Large Bearing

Schaeffler unveiled a sealed 241/1250 spherical roller bearing, reportedly a world’s first. Featuring an outside diameter of nearly 2 m, the ultra-large bearing was specifically designed for the highest-capacity high pressure grinding roll crushers. It is engineered to prevent the crushing materials from contaminating its internal components. The bearing’s rolling elements reportedly weigh 60 kg each. The outside diameter of the molded seal is 1.4 m. Metal shields with an optimized polymer seal house the bearings.

Nuclear Gauge for Single Platform

The Thermo Scientific InterfacePRO, a nuclear gauge for density, level and interface measurement of highly viscous process materials, allows users to standardize all process instruments on a single platform, and to reduce the size of radioactive materials used on site. The gauge is optimal for traditional gamma transmission applications (level and density measurements) or in gamma backscattering applications on large process vessels and pipelines. It uses non-intrusive and durable gamma backscatter technology that is designed to minimize maintenance and lengthen instrument life. The InterfacePRO gauge is a component of the Thermo Scientific NextGEN Nuclear Platform, which also supports the Thermo Scientific DensityPRO and LevelPRO gauges.

Surveying Laser Scanners for Pits, Piles

Maptek announced its third generation I-Site XR3 and LR3 laser scanners, which are 30% smaller and 25% lighter, with 2.5 times faster data-acquisition and a 25% improvement in range capability over predecessor competition.

OTR Tires Showcased

Bridgestone Americas, Inc., showcased the Firestone VersaBuilt tire line, its first full line of off-the-road (OTR) radial tires. Key features include steel casing and SideArmor sidewalls; non-directional, self-cleaning tread; three different tread patterns, the Firestone VersaBuilt All Traction (G2/L2), the Firestone VersaBuilt All Purpose (E3/L3) and the Firestone VersaBuilt Deep Tread (E4/L4); 11 different size offerings; and a five-year limited warranty. Firestone VersaBuilt tires provide solid traction for loaders, graders and earthmovers, ensuring these machines perform at their best in a variety of conditions, ranging from muddy to rocky surfaces, the company reported.

Rod System Cuts Deviation

Rockmore launched its new Vector Rod System, featuring the new XT thread design. The design incorporates revolutionary new guided cylindrical contact zones between the male and female thread joints, the company reported. The zones increase the lateral support between thread joints and stabilize the connections to provide greater energy transfer. The thread guide feature improves thread alignment, which minimizes the impact duration when rattling rods to uncouple connections. The system also enables straighter holes with less deviation, the company reported. The XT thread profile is based on the traditional trapezoidal T thread design and is therefore compatible with industry standard thread types, such as T38, T45, and T51.
