Vocational truck
Underground truck
goes electric
Atlas Copco offers a suite of seven underground loaders and
trucks that use electricity as the primary power source. The
Green Line, it says, is designed to help underground mines
address challenges including energy efficiency, carbon emissions, and environmental footprints. Underground mine
trucks include the EMT35 and the EMT50 (pictured), with
respective loads of 35 and 50 tons. Said to be twice as fast
as any diesel truck of similar size, the manufacturer touts
the trucks as the "world's most productive trucks." By using
electricity, energy consumption is reduced by up to 70 percent. Regenerative braking returns energy to the grid, meaning that about 30 percent of the energy consumed up a ramp
is regenerated going back down.

Tracking operator fatigue
Caterpillar Global Mining entered an alliance agreement with Canberra, Australia-based Seeing Machines Limited to deliver and support operator fatigue monitoring technology. Developed by the Australian company, the monitoring systems use patented eye and
head tracking technology to detect operator fatigue and distraction, as well as to alert the mine controller and the machine operator.
The alliance agreement also supports collaboration in future product development. The Driver Safety System, a commercial system
for mining trucks, is working on more than 20 mine sites and 1,500 vehicles.

Wheeled jaw crusher
Irock Crushers introduces the Wheeled Jaw Crusher-2644
for use as a primary crusher. Powered by a 350-horsepower
Caterpillar C-9 Acert Tier 3 engine, the unit can produce up
to 370 tons per hour. With a capacity of 10.5 cubic yards, the
hopper was designed significantly larger than similarly sized
crushers. The crusher is equipped with a 48-inch by 36-foot
discharge belt that features a fixed discharge height of 11 feet
— said to be the highest stockpiling height in the industry —
and can easily be paired with screening units. A hydraulic adjusting chamber allows operators to adjust crushing size from
a 2-inch minimum closed-side setting to a 6-inch maximum
side setting. The machine includes a 24-inch grizzly bypass
conveyor, as well as a 40-inch by 14-foot feeder with a 5-foot
grizzly bar section to ensure proper classification of material.
