motor ”, Sylvain Reynier , R & D Director for Aramine , explained .
“ Aside from having been calculated to be powered by diesel or batteries , the L350s have both been designed for an intensive use and reduced maintenance ,” he told IM . “ Indeed , a lot of components have been oversized , such as the hydraulic system , with total filtration on suction and return . The central articulation designed with conical bearing , too , is also the same as what our competitors are using on 7 t loaders .”
Such redundancy should increase the lifetime of the machine , according to Reynier .
Comparing the L140B with the L350B , Reynier said the size and voltage difference between the two battery-powered loaders in its line-up had “ compelled our engineers to increase the voltage on the L350B ”.
He reiterated the two will share as many similar components as is possible to ease the use and maintenance processes for existing Aramine machine operators , but he also highlighted several positive updates .
Reynier said : “ The ergonomics for the operator have been improved as the cabin is larger than it was on the L140B , and it is enclosed . Both the L350B and L350D have been made with a unique cabin design in terms of comfort and security . You can spot that this is the only cabin on the market without hydraulics in the operator compartment to ensure total

security and allow extra space and ergonomic operation for the operator . This also reduces the need to cool the inside of the cabin .”
While the L350B will be equipped , as standard , with the same lithium-iron-phosphate technology the company has employed on all its battery-powered machines to date , Reynier did say clients will also have the option to choose Epiroc battery technology on the L350B .
Many existing L140B users will be using the QRS option on board the loader , which allows the machines to run longer by providing a quick disconnect battery module for swift battery swapping .
This existing QRS system with crane will also be available for the larger L350B batterypowered LHD . Reynier confirmed another battery-swapping option is also being worked on .
“ A new system for an autonomous battery swapping system without crane use is in development in our R & D department with a patent pending ,” he said .
What about a matching batteryelectric truck for the L350D ?
Reynier had this to say : “ Aramine ’ s R & D department is currently working on a bigger battery-powered mine truck , the T1200B , which will match the mining loader L350B , fitting the same gallery size . The T1200B will be able to carry three full buckets from the L350B .”
The PMKM 8030 has a 8 cu . m dump box , a mining safety package including ROPS / FOPS protection and SAHR brakes , plus a new spacious , comfortable cab with 90 ° rotating driver ’ s seat
Higher payload in small envelope
Speaking of dump trucks , Germany-based Paus has released a new 16 t payload underground truck suitable for the narrow-vein mining market .
The brand-new PMKM 8030 dump truck is one of most compact and powerful machines in its class , according to Paus , coming with EU Stage V / US Tier 4 Final engine options from Cummins and Caterpillar with up to 190 kW of power .
Paus explained : “ Whereas the wellestablished sister machine , type PMKM 8010 , is a machine with less width at increased length and height , the new PMKM 8030 comes up with a broader , shorter and narrow design at a reduced loading height and with improved driving characteristics due to the lowered centre of gravity , bigger tyres and new axles with integrated oscillation .”
A more powerful driveline and increased performance at reduced lifting and tipping times means the overall cycle time has been reduced significantly , according to the company .
The PMKM 8030 has a 8 cu . m dump box , a mining safety package including ROPS / FOPS protection and SAHR brakes , plus a new spacious , comfortable cab with 90 ° rotating driver ’ s seat .
Options for the dump truck include an ‘ HD ’ dump body , ‘ LD ’ dump body , and tailgate . The machine also has a data communication interface through PausConnect , the OEM ’ s lifecycle cost monitoring solution . The truck can operate as standard in temperatures ranging from -20 ° C up to 50 ° C .
Further state-of-the-art safety functions like a button for brake test , three-point seat belt , seat belt and / or seat contact monitoring , HRD onboard fire extinguishing systems , birds-eye view camera , tyre pressure monitoring , gas monitoring system and others are available as options .
