BAUMA PREVIEW to a mine site ’ s electrical network , powered by the customer ’ s energy source of choice . It offers increased truck fleet productivity and the potential for a reduction in fleet size while retaining the same productivity compared with the use of standard trucks , according to the company .
The potential for a significant reduction of diesel fuel consumption and a smaller carbon footprint by decreasing the truck fleet ’ s CO 2 emissions confirms the Trolley Assist System as an effective first step on the road to zero emission mine sites of the future , according to Liebherr .
Liebherr already has 56 trucks fitted with the system operating out in the field across three mine sites .
The company ’ s recently launched Technology Product portfolio will also be showcased in Munich , with the Truck Loading Assistant , Performance Monitoring and Application Severity analytic products among the list of solutions on show . Liebherr Power Efficiency and the Bucket Filling Assistant , the latter of which offers the first step towards excavator automation , will also be presented .
Mining company attendees will also gain some insights into the OEM ’ s hydrogen strategy , with Liebherr Components ’ first hydrogen engine , the H964 , being highlighted at the event .
Liebherr will also discuss its recently announced tie-up with Fortescue Metals Group , which has a hydrogen element to it .
Back in June , the two companies signed an agreement for the development and supply of mining haul trucks integrating zero emission power system technologies being developed by Fortescue Future Industries and Williams Advanced Engineering .
The phased supply of haul trucks as part of this agreement is anticipated to commence following a two-year joint development period . This is intended to enable the development and integration of Fortescue ’ s proprietary-owned battery electric and fuel cell electric power system into Liebherr ’ s proprietary-owned base truck .
Electric-drive and smart solutions
Across its plus-7,000 sq . m of Bauma space , Komatsu is set to present attendees with a record number of machines – 42 – that are new or well-recognised products and services that , it says , improve total job site efficiency and create real customer value .
The standout among these will be the PC4000-11 electric drive excavator , which , with its 22 cu . m shovel capacity , is a match for 150- 240 ton ( 136-218 t ) trucks . It is also representative of the company ’ s knowledge and experience in developing , manufacturing and maintaining electric driven hydraulic excavators .
Komatsu Germany Mining started to build the first electricdrive hydraulic mining excavator in the early 1980s . Now , almost 40 years later , Komatsu has delivered more than 250 of them worldwide .
“ With over 7 million operating hours , Komatsu is one of the most experienced and most successful companies developing , manufacturing and maintaining this type of machine ,” it says . “ The unique advantage of the electrically driven hydraulic excavator lies in the reduced operating costs , made possible by the elimination of diesel costs and the fact that they are not obliged to comply with any emission regulations .”
Equipped with the KOMTRAX Plus system , KomVision and Argus PLM , the PC4000-11 is digitally connected , benefits from constant monitoring , is equipped with safe operating mechanisms and offers efficient loading operations , the company says .
Other machines set to feature on the Komatsu stands include the 92.2-t-payload HD785-8 rigid frame off-highway haul truck and the 20.7-t capacity WA800-8 wheel loader .
Digitalisation is another essential element for improved productivity and , at Bauma 2022 ,
The standout on the Komatsu stand at Bauma 2022 will be the PC4000-11 electric drive excavator , which , with its 22 cu . m shovel capacity , is a match for 150-240 ton ( 136-218 t ) trucks
Smart Construction / Earthbrain will show a new way of working , with unique solutions to support and improve customers ’ businesses , Komatsu says .
Smart Construction is a solution for implementing highly productive , clean and safe work sites by connecting various site-based information via ICT . EARTHBRAIN , a new company setup by Komatsu , NTT DOCOMO , Sony Semiconductor Solutions and Nomura Research Institute , incorporates digital twins at sites based on its visualisation devices and applications for real-time remote monitoring , analysing and optimising of terrain , equipment , operators , materials , safety and environmental factors .
The Komtrax Next Generation and Komtrax Data Analytics booths , meanwhile , will explain how Komatsu ’ s wireless monitoring system can simplify decision making for all those who work to deploy equipment effectively or to improve
