for grease transfer to linkages , and integrated motion hard stops increase reliability . A new bucket design with an oversized spill guard offers cast or plate lip options , and the cast Z- link integrates lubrication channels and optimised geometry for added durability .
“ Operators will appreciate the intuitive userfriendly touchscreen . Autogenerated diagnostic measurements and adjustments , as well as live data readouts ensure your operators have all the information they need for top performance .”
In addition to the models already discussed , the new WX03 is also set to replace the LT270 . The two hybrid big machines have a name change , the 18HD will become the WX18H and the 22HD becomes the WX22H . Lastly on underground trucks , the HX07 will replace the 7TD and the HX16 is to replace the 16TD .
In orders , the underground mining services company Mas Errázuriz has acquired two 10 t class LHDs of the model LT1051 from Komatsu Mining , to be used in a copper mine in Chile ’ s Region IV , and replacing competitive equipment .
Emerson Tobar , Account Manager at Komatsu Mining in Chile said the model ’ s main attributes are being safe , robust and having a simple maintainability , which prolongs its useful life and reduces maintenance , in addition to its high break out force , which in the field gives a lot of confidence towards productivity . Komatsu says the LT1051 “ is ideal for medium-size openings for both load-and-carry and truck-loading applications . The LT-1051 is perfect for heightrestricted areas and can be equipped with an optional ejector bucket .” It adds that it is designed specifically for ease of use and maintenance , with simple operation gauges and a rugged long-life structure , providing the lowest possible total costs of operation including low capital costs .
The order is a boost for Komatsu ’ s underground equipment business in Chile where it still has a relatively small market share . However , it does have a foothold in the future technology side as it already has large hybrid 18HD 18 t class LHD operating at Codelco ’ s El Teniente underground copper operations which Codelco says has increased productivity by more than 10 % and cut diesel consumption by 15-20 %.
GHH Group drives underground efficiency
As the trends in the mining industry move toward battery , electric and ‘ environmentally friendly ’ products , GHH Group says it continues to support the needs of customers . “ Not only does GHH have a diverse fleet of loaders and trucks , covering low profile , narrow vein and mass mining product offering but in a drive to protect operators and the environment GHH also has one of the largest Stage V engine load and
GHH Group ' s impressive MK- 42 truck and LF-14 loader
haul fleet amongst its peers . Nearly all the loaders and 100 % of the truck range is available in Tier 3 , Tier 4f and Stage V engine emission packages .”
GHH also offers flame-retardant and biodegradable hydraulic fluids setting an impressive pace in protecting people and the environment . The thermally highly stable hydraulics are 98 % biodegradable thus reducing damage to the environment , in the case of hydraulic damage , and significantly reducing the ‘ clean-up initiatives ’ in the event of a spill . These fluids are also flame-retardant therefore also reducing the risk of accidents for the operators , machines and the production site by not allowing the flame to propagate .
GHH has been manufacturing tethered electric loaders for over 20 years and , in a further drive to support the environmentally friendly product range , is also focused on technology implementation to reduce costs , and time , associated with ‘ panel to panel ’ machine movement of tethered machines . To do this end GHH has developed , and relatively recently launched the LF-19EB tethered electric battery loader , which utilises regenerative battery power to tram panel to panel .
“ The LF-19EB is first in a long line of new technology developments in the line of battery electric loaders that the company is working on . There is currently a new SLP-14E under development , due to launch towards the end of the year , which has a brand new , innovative direct drive electric drive train that will form the baseline for future developments . Axle to motor to axle with no gearboxes and direct frequency controlled – this design has significantly less components resulting in less maintenance , less breakdowns and ultimately reduced maintenance costs and improved availability and potential utilisation . And with very little hydraulics , except for the brakes and boom and bucket , the expected reduction in hydraulic related breakdowns soars even further . The
proven vertical coiling cable reel design , with spooling control , significantly improving the cable life is a standard on this machine . The SLP-14E is not only a technology trend setter but also provides for improved visibility and comfort for the operator , with a brand new ergonomically design cabin and frame layout . GHH is starting with the electric drive train and battery electric drive and moving towards full battery drive train designs in the development pipeline .”
GHH has also recently launched its new LF-7 , 7 t loader . It comes with the biggest bucket and the best power rating , with highest operating slope angles , in the 7 t payload class . All that combined in a super low emission , super compact package .
The loader and truck range are all available with PDS level 9 interface as well as automation ready and available with GHH inSiTE , its digital analytics solution .
Understanding of mining machines technical conditions and efficiency of their utilisation with the use of modern digital solutions has been on the agenda for quite some time . Development of mines communication infrastructure and machine control system architecture allows tracking the processes and taking effective corrective measures , in near-real time , technically possible right now . Yet the question remains how to get people engaged in actively using the system without spending too much time on this process and getting the value add out of it at the end of the day .
GHH in cooperation with talpasolutions , from Essen in Germany , has developed GHH InSite Suite , a web-based end-to-end IIoT solution , allowing stakeholders at various levels in mining companies ´ hierarchies to gain useful insights and manage the efficiency of single machines as well as entire fleets .
The real value of GHH InSiTE in comparison with the similar systems on the market lies in not only ensuring the integrity of the collected and managed data but maximising the value add
