WORLD PROSPECTS
Liebherr readies new 600 t R 9600 hydraulic excavator
Liebherr says its newly launched R 9600 hydraulic excavator is setting new standards in the open-pit mining market .
The successor of the popular R 996B , the R 9600 enters the market after gaining a year of field experience in Australia , the largest market for 600-t class excavators . This new development builds on years of customer-centric research and is based upon the successful R 9800 800-t excavator , Liebherr says .
A total of eight units will be operating in Australia by end of 2021 , with the R 9600 entering serial production at the end of this year .
After testing the first prototypes at the factory proving grounds in Colmar , France , in early 2020 , the first R 9600 pre-series excavators started operating in iron ore and coal applications in Australia . Liebherr , together with its customers BHP and Thiess , started the partnered validation of the first two units in the field . Backed by this successful validation phase , the R 9600 is ready to enter the global market today .
The new R 9600 aims to reach the highest standard in terms of safety , sustainability , performance , lifetime , total cost of ownership ( TCO ), ease of maintenance and more .
The R 9600 is equipped with two QSK50 Cummins engines with advanced combustion technologies . Understanding that fuel costs form the major portion of the TCO for mining machines , Liebherr has developed and implemented proprietary LPE ( Liebherr Power Efficiency ) systems for the engine and hydraulic system controls to , it says , substantially reduce fuel consumption without compromising on overall machine productivity .
For emission regulated regions , a US EPA Tier
4 Final / EU Stage V compliant version is available with the latest SCR after-treatment technology . An electric drive version will also be available soon .
The R 9600 attachment makes use of smart component design such as the patented ‘ EVO ’ backhoe bucket , hydraulic cylinders , shift levers , bucket links and attachment pins . The result is an increased overall production rate without compromising on component lifetime , Liebherr says .
In standard backhoe configuration with a Heavy Duty wear package , the R 9600 comes with a 37.5 cu . m bucket to deliver an ideal truck / shovel match with Liebherr mining trucks . It loads 190 t trucks in three passes , T 264 240 t trucks in four passes , T 274 300 t trucks in five passes and T 284 375 t trucks in six passes .
The excavator is also available in face shovel configuration equipped with a 37 cu . m shovel as standard with a Heavy Duty wear package .
Designed to be used in all applications globally , the R 9600 is built to last over 80,000 machine operational hours , and includes a completely new upper carriage structure for improved machine reliability .
The R 9600 has a brand-new 14 cu . m cabin , designed to reduce vibrations and limits noise to 69 dB , Liebherr says . This cab is positioned back on the left side , standardising with other excavators in the range .
The R 9600 also offers a superior machine perimeter visibility system comprised of four cameras at strategic locations on the rotating upper carriage . The dedicated monitor inside the cabin provides continuous 270 ° vision around the machine .
Setting new standards in the mining industry , the R 9600 is equipped with the Liebherr Assistance Systems . These advanced on-board applications are designed to support the operators in becoming more efficient through analytics and actionable insights from live data , the company said .
The Truck Loading Assistant , meanwhile , helps the operator attain optimal productivity and efficiency . With 99 % measurement accuracy , the system measures the instantaneous bucket payload and provides real-time information to the operator .
The first HEX Automation Product introduced to the mining industry from Liebherr is the Bucket Filling Assistant , an adaptive or semiautonomous digging product available as an option for the backhoe version of the machine . This allows for easier and faster bucket filling with a consistent bucket fill factor even in the toughest digging conditions , boosting productivity while reducing the operator ’ s fatigue level . www . liebherr . com
Barkom bullish on diamond coring
Barkom Group Drilling Rigs and drilling N size holes . As the drill rig comes with a
Equipment , founded in Ankara , crawler , it can also easily be driven to the drilling
Turkey , in 1987 , has leveraged site . All drilling functions are performed using industry experience and its significant the ergonomic and user-friendly control panel ,
R & D efforts to start manufacturing which also displays all the drilling diamond coring exploration drilling rigs parameters necessary to ensure under its own Bulldrill ® brand . The new productive drilling .
Bulldrill BD2000S , it says , has already been The BD2000S also proven in applied mechanical tests provides the torque and in Barkom Group ' s R & D Centre . rpm necessary for BWL
When retrieving large core ( 2,300 m ) to PWL ( 800 samples , the load sensitive m ) size coring , making it , tandem pumps , variable the company says , the displacement hydraulic motor and most powerful rig in its powerful transmission can produce over class . All hydraulic 9,000 Nm of torque , plus the special gear group components are carefully selected from array provides fast penetration rates through the global brands . The rig also has a new buttress rotary unit . and mast system , which further increases The drilling depth capacity is 2,000 m when productivity . A newly designed straight wrapped
wireline winch wraps the rope more smoothly along the width of the drum .
All important components are positioned so they are easily accessible during maintenance . For less footprint to control carbon emissions , the rig has a modern Tier III Cummins QSL 8.9 engine . The rig is ideal for deep drilling and , despite its strength , the design is compact . An 18 t capacity Braden winch hoist allows depth capacity beyond its class . The PQ chuck holder and PQ rod holder are field tested and designed to offer performance and reliability .
The open-faced mast features a common centre line through the chuck and feed cylinders , decreasing wear on components . Simple hydraulics and structural design make this drill easy to operate and maintain . The rig can also be customised according to different conditions , including changing the capacity , hydraulic systems and mechanical elements . www . barkomas . com
