MINEXPO PREVIEW
models , fitting galleries from 4-15 sq . m . The QRS , designed by Aramine ’ s R & D department , and currently mounted on its miniLoader L140B , allows the machine to run constantly except for the 15 minutes required for battery-swapping using a specialised crane .
The L350B , the new 3.5 t battery-powered loader being displayed , will use the same QRS system for battery swapping , but an optional autonomous battery changing system – without the need for a crane – is in the works .
Aramine also remanufactures mining equipment as new from different OEM brands . This activity , part of Aramine ’ s sustainability approach , is realised according to OEM specifications and includes the latest engineering design and performances upgrades , using only genuine spare parts and including worldwide warranty , it said .
On its second booth , Aramine will showcase its spare parts offering . Under the name ‘ Smart Parts ’, it has more than 1.5 million manufacturer references computerised and 850,000 of these in stock at different warehouses . At its Francebased workshop , Aramine can propose remanufactured components too .
GHH Group ’ s MINExpo 2021 stand will be filled with key artwork and video material to focus attendees ’ attention on its niche and new product offerings , sharing both its successes as well as future endeavours .
The recently launched LF-7 loader will be a focal point of the GHH booth . This 7 t payload LHD is fit for large narrow vein and smaller mass mining operations , measuring only 8,900 mm long in driving position , 2,240 mm wide at the bucket and 2,200 mm high at the cab when loaded . It has an approximate operating weight of 18 t .
The loader comes with the biggest bucket ( 3.6 cu . m ) and best power rating in its class , according to the company . The LF-7 is powered by a 164 kW Cummins diesel engine that complies with US Tier 3 and Tier 4 Final , and EU Stage V emissions standards . It can cope with gradients of up to 28 % and reach speeds of up to 27 km / h .
The cab is ROPS / FOPS certified and offers a high level of safety and ergonomics with comfortable t-back seat , low whole body vibration and reduced noise levels , as well as ride control and great visibility . The LF-7 is optionally fitted with GHH inSiTE , GHH ’ s digital analytics solution , where all relevant vehicle data can be accessed and remotely evaluated . It is proximity detection interface-ready , while bucket weighing and tyre pressure monitoring systems are optional .
GHH also has an offering for the low-profile mining market , with a fleet of loaders , rigs and utility vehicles .
On its MINExpo stand , GHH will be highlighting the latest launches of a batteryelectric rig ( the FM1.7LE ) and bolter ( the RM1.8KE ) currently running at one of KGHM ’ s copper mines in Poland , as well as the SLP-8 low profile loader currently running in southern Africa . Supported by its partner company , UVB , GHH has a huge range of utility vehicles supporting these primary machines .
The modular design SLP-8 boasts 178 kW of power , the largest carrying capacity in its class , excellent ground clearance to navigate undulating foot walls , as well as unsurpassed visibility and ergonomic comfort in the operator ’ s compartment , GHH said .
The battery-electric drill and bolting rigs were developed to reduce greenhouse gas emissions , improve safety and reduce maintenance requirements .
The RM1.8KE can work in galleries from 3 m up to 5.8 m in height and is equipped with a 1.8 m-high mechanised bolting mast for nine bolts . The 120 kWh sodium-nickel battery installed on board can be recharged using the existing mine power network .
The FM 1.7LE is designed to drill blast holes between 41-76 mm in diameter and net length of 3.2 m in heights above 1.7 m . Even with the battery charger on board , it is still the lowest height machine in its class , with a tramming height of 1.65 m . It is also able to operate on slopes of up to 15 °.
More precise and effective drilling can be conducted with optional easy drilling monitoring system , or a more advanced Feeder Guiding System ( FGS ). Both systems are suitable for drilling in room and pillar mining applications .
JH Fletcher & Co plans to display a variety of equipment , including two machines from its roof bolter product line , at this year ’ s MINExpo .
The Fletcher Model N3016-AD is a diesel-powered
The 7 t payload LF-7 LHD is fit for large narrow vein and smaller mass mining operations
carousel roof bolter designed for bolting in narrow headings as small as 10 ft x 10 ft ( 3 m x 3 m ). With safety front and centre , all drilling and bolting operations are performed from the operator ’ s deck .
The Fletcher Model N3112-B / E is a “ man-up ” roof bolter designed for a maximum operating height of 13 ft ( 4 m ). The machine is equipped with a lithium-ion battery for fully functional battery-electric operation . It is designed with a battery management system to help ensure cells stay within a safe operating envelope under all test conditions . This system also includes cellto-cell propagation prevention . The batteries are enclosed in a flame arrestor to reduce external vented heat in the unlikely event of cell thermal runaway . This model is designed with on-board charging and boasts quieter operation , the company said . In addition to roof bolting , those visiting the
MINExpo 2021 attendees will be able to interact with the FletchTech virtual interactive mining simulator on its booth , with a J352 ( dual boom drill jumbo , pictured ) one of the machines featured
Fletcher booth will see its J352-LS dual boom drill jumbo on display . This comes equipped with the
GOAD-Automated Entry Driver ( AED ) system and is designed for headings as large as 60 ft ( 18.2 m ) wide and 35 ft ( 10.7 m ) high . The AED system is one of Fletcher ’ s latest technological advances , helping create a more
