MINEXPO PREVIEW II
priming and re-priming . Equipped with a 165 kW engine , the 6JSCL is ideal for high pressure applications such as pit dewatering and water transfer , as well as bypass projects and other jobs requiring high pressure pumps .
The innovative priming system prevents product blow-by from discharging , keeping the surrounding environment clean and safe . The Enviroprime System uses an air compressor to divide air from water , which keeps the pump ’ s venturi from clogging . With the air escaping separately , the fluid can continue through the pump without any unwanted blow-by discharge .
An on-board compressor supplies air to a venturi , providing powerful air suction to the system chamber located at the pump inlet . The chamber empties air from the pump ’ s suction line causing it to fill with water . When the suction line is fully primed , an internal float rises in the Enviroprime System chamber , shutting off the air suction , preventing blow-by leakage to the ground from the venturi opening . During operation , if prime is lost or air enters the pump suction line , the float automatically actuates , reapplying suction to restore prime or eliminate air pockets .
H-E Parts International , one of the largest independent global suppliers of aftermarket parts , components and solutions for mining , heavy construction and energy , continues to provide innovative mining enhancements . Recently , H-E Parts engineers were named in a patent that corrects pre-mature wheel bearing failures on Komatsu 930E front corners .
After studying the original manufacturer ’ s design , H-E Parts engineers determined the underlying cause of the failures . The oil used to lubricate the wheel bearings was also shared with the braking , cooling and general hydraulic systems . The low viscosity cooling oil increased likelihood for cross contamination and undesirable bearing wear .
The H-E Parts team incorporated Control Fit Birrana™ technology as part of their solution . Working with H-E Parts engineers in Adelaide , Australia , they designed a solution that guarantees longer life , improved reliability and lower cost repairs .
“ H-E Parts added internal enhancements to separate the oil systems , decrease the bearing temperature and enable the system to reach its full design life ,” explains Lane Gobbs , one of the engineers named in the patent .
“ When we design solutions such as these , we like to work closely with our customers ,” says Ken Pitman , VP Engineering . Pitman , also named on the patent , routinely collaborates with customers to resolve problems .
The H-E Parts solution was designed and tested in six months . The first unit delivered is still in service today . Currently approaching
Model of a 930E front corner
16,000 hours , the H-E Parts enhancement has doubled the average life . The enhancement has been installed on 90 haul trucks in Canada , the US , Australia , Chile and Peru .
“ We are a global company that functions locally ,” says Pitman . “ Our engineers are highly specialised and collaborate quickly to resolve customer problems .” H-E Parts is located in all of the major mining centres and is able to respond faster , and be more flexible and more creative than larger competitors . “ We are proud of the product because it shows our ability to listen to our customers and provide innovative and economical solutions for them ,” says Pitman .
H-E Parts International says it “ has become the only global alternative to the traditional OEM channels of distribution . The company has seven engineering centres and 22 global remanufacturing and repair centres . With almost 900 employees from Billings , Montana to Perth Australia , H-E Parts focuses on innovative solutions to help customers get the most out of their machinery and maintenance dollars .”
John Deere will showcase its experience developing integrated electric powertrain solutions for rugged off-highway applications . To highlight the full line of electric powertrain components currently used in some John Deere equipment , John Deere Power Systems and John Deere Electronic Solutions will exhibit a diesel engine , a generator pump drive , an inverter , and an electrically driven transmission designed for the demands of the construction and mining industries .
John Deere Power Systems will exhibit product offerings from its lineup of Funk™ powershift and hydrostatic transmissions , axles and pump drives , all designed for the unique needs of offhighway mobile and stationary equipment . A PowerTechTM E 4.5L engine certified for use in underground mines by CanmetMINING will also be on display . This engine offers a power range of 93 to 104 kW with full-authority electronic controls , two-valve cylinder heads , a highpressure common-rail fuel system with electronic fuel injection and a fixed-geometry turbocharger .
John Deere Electronic Solutions will showcase products developed to improve performance and increase productivity within a variety of applications , including the PD400 inverter .
There will also be an electric generator pump drive and a three-speed electric motor transmission on display . Each of the electric powertrain products on display are designed to offer reliable and durable solutions for a variety of applications .
Since the last MINExpo exhibition , Logimine has grown and opened new offices in the Philippines and New Caledonia , helping mines of any size around the globe increase plant and equipment efficiency , safety and durability . It will release its ‘ Horizon all-in-one ’ dispatch system comprising : n Advanced office software - Total Quality
Management App for plant supervision n On-board terminals with intuitive operator interface compatible with all vehicle types n Radio UHF / VHF and Wi-Fi radio communication n RTK GPS positioning .
Logimine ’ s Horizon software can be installed either on Cloud or on the mine ’ s server . It holds a range of modules enabling real-time supervision of the plant from anywhere . Managers can visualise and track vehicles on aerial maps and replay vehicle movements . Various activities such as loading , drilling and blasting in each zone of the mine site can be thoroughly controlled . The position of the vehicles , their destination , speed , loads , cycle times and wear ( i . e . tyre pressure and temperature ), as well as stocks and quality control of materials and aggregates are also monitored in real time . The software ’ s automatic vehicle dispatch functionality helps to optimise productivity . Managers can view activity reports , observe the data algorithms and use these to decide the most cost-efficient routes and schedules for a vehicle , helping to improve efficiency and minimise vehicle maintenance .
Intelligent on-board terminals are mounted in the cabins of trucks , loaders , excavators , bulldozers or drills to guide operators by displaying payload data , the position of the bucket or drill stem and the type of material to load , its origin and destination . Logimine will demonstrate its ‘ on the move ’ Ez-Scale weighing system for loaders delivering an accuracy of ± 0.5 %. The terminal displays the material to be handles and advises the operator when and where to load or unload and when to stop loading .
Data collected from vehicles and components such as payloads , on-board terminals or TPMS ( Tyre Pressure sensors ), can be transferred into the cloud where it is stored and processed . Managers can access and update information online at any time from any PC or smartphone freeing them from the control room .
