MINEXPO PREVIEW
With the Hitachi EX2600-7 , EX3600-7 and EX5600-7 ( pictured ), customers can choose from a Cummins or mtu EPA Tier 4 Final engine option
The EX-7 Series includes the EX1200-7 , EX2000-7 , EX2600-7 , EX3600-7 and EX5600-7 , all available as electric or fuel-efficient models that help reduce total costs of ownership while achieving superior productivity , the company said .
With the EX2600-7 , EX3600-7 and EX5600-7 , customers can choose from a Cummins or mtu EPA Tier 4 Final engine option . For non-regulated countries , customers can choose from a Cummins or mtu engine option that features Fuel Consumption Optimisation ( FCO ) settings for improved efficiency . The EX3600-7 fitted with a Cummins Tier 4 Final engine , which also has FCO technologies but uses diesel exhaust fluid , contributes toward 4 % net fluid savings while the mtu FCO engine without DEF features 7 % net fluid savings as compared with the previous model , the EX3600-6 .
The smallest of the EX-7 Series excavators , the EX1200-7 ( 118,000 kg in shovel configuration ) features a 4.5 % increase in bucket capacity with a 7 cu . m capacity . Equipped with optimised swing control , the new machine also has an improved hydraulic system with a flow regeneration valve to reduce power requirements from the hydraulic system and engine , lowering fuel consumption and improving pump life .
One key product line is Hitachi ’ s EX-7E ( Electric ) series mining excavators , which includes the EX2600-7E , EX3600-7E and EX5600-7E available in North and South America .
“ One of the key benefits of a Hitachi EX-7E Series mining excavator is efficiency ,” the company said . “ For example , a high torque motor replaces the conventional combustion engine . Electric motors are able to produce high torque with greater efficiency with fewer service intervals than a diesel engine .”
Hitachi ’ s Tier 4 Final-certified EH5000AC-3 haul truck combines “ time-proven ” hauler technology with a high-efficiency Advanced IGBT AC-Drive system . The truck , which is equipped with a Cummins QSKTT A60-CE diesel engine that generates 2,125 kW at 1,900 rpm and meets Tier 2 EPA emission requirements , helps raise profits by lowering fuel and maintenance costs , the company said .
On top of this , battery-electric vehicles and trolley trucks will also be up for discussion at the Hitachi booth .
Volvo Construction Equipment is set to showcase a line-up of its largest loaders , rigid haulers and excavators at MINExpo .
The new Volvo R100E rigid hauler ( pictured ), built to drive down operating costs for customers by boosting productivity , uptime and operator comfort , will be one of the headline attractions on its booth .
The 95 t payload truck is powered by a 783 kW Tier 4 Final engine and a combined drivetrain to provide high torque capabilities , unparalleled pulling performance and class-leading rimpull for optimal travel times , Volvo said . It also has a 60.4 cu . m capacity V-shaped body for optimum load retention and minimal material carry-back .
The 90 t Volvo EC950F crawler excavator , the largest in Volvo ’ s lineup , is also set to be shown
off . This excavator is equipped with a 450 kW Volvo D16 Tier 4 Final engine that , the company says , delivers high torque at low rpm .
This machine is paired with a Volvo A60H articulated hauler , with the EC950F filling the 55 t , 33.6 cu . m haul truck in just four bucket passes , with an average cycle time of 20-25 seconds .
Finally on the stand is the Volvo L350H wheel loader , fitted with next-generation hydraulics and powered by a Tier 4 Final D16J engine for high torque at low rpm . The L350H comes with a higher capacity 7.3 cu . m rock bucket for maximum performance , plus an optional load sensing hydraulic system that works in harmony with the drivetrain , increasing response times and lifting and lowering speed of the newly designed buckets . This can result in up to 5 % faster cycle times , according to the company . It is also equipped with the latest technology dedicated to reducing fuel consumption and engine emissions .
Sandvik has new battery-electric vehicles of its own to show off in Las Vegas , alongside its developments automating both underground equipment and open-pit surface drills .
The OEM will have several of its latest innovations on display for the first time anywhere at the event , including its AutoMine ® Concept vehicle . The first fully autonomous battery-electric vehicle for underground mining , this vehicle is equipped with new sensing capabilities and artificial intelligence to help the
