ELPHINSTONE DESIGNS AND MANUFACTURES QUALITY UNDERGROUND MINING SUPPORT SOLUTIONS

Elphinstone Pty Ltd , located in Tasmania ’ s North West , is a leader in the design and manufacture of underground mining support vehicles . The company has developed and released six new vehicles in the last 24 months with the first production units already operating in North America , South America , and Australia .

There are two base platforms on which there are numerous specialised underground attachments for each different application . The first is the WR820 series , a 20-t nominal base platform , and the second is the WR810 series , a 10-t nominal base platform . The WR820 Series currently comprises a water cannon , an agitator ( 8 m 3 or 10 m 3 ) and a water tank . The WR810 Series currently comprises a scissor lift , a 6 m 3 agitator , fuel and lube truck , water cannon and delivery . At the heart of both platforms are CAT engines , world-renowned for their smooth torque delivery , reliability , fuel efficiency , readily available parts and product support . The WR810 Series equipped as standard with CAT ’ s C7.1 ACERT engine meets Tier 3 EPA regulations . The engine delivers 158 kW ( 214 hp ) net and 922 Nm of torque from its 7.1-litres of displacement at 1,400 rpm . The WR810 optioned with a Tier 4 Final version of the CAT C7.1 engine delivers 151 kW ( 202 hp ) net and 870 Nm of torque from 7.1- litres of displacement at 1,400 rpm . Countries with strict engine emission levels will now benefit from this option . Due to their extra payload capacities , the WR820 Series fitted with CAT ’ s C11 ACERT engine delivers 239 kW ( 321 hp ) net and 1,430 Nm of torque from 11.15-litres of displacement at 1,300 rpm .
Backing up that power in the WR810s is a CAT five-speed ( three-speed reverse ) transmission fitted with a lock-up torque converter . The WR820s feature a CAT six-speed ( single speed reverse ) powershift transmission and lock-up converter , which stops converter slip under certain load and rpm conditions .
Safety is one of the most important aspects of any piece of machinery employed in the mining world . Integrated into the WR820 and
The WR810 Fuel & Lube truck delivers in situ top-up of lubricants , grease , and fuel
WR810 operator station is an ISO 3471:2008 standard ROPS and ISO 3449:2005 standard FOPS that offers protection to the operator .
Other safety features include fuel water separators made of non-flammable material , firewalls and heatshields , machine interlocks , centralised isolation points ( engine disconnect switch , starter isolation switch , jump-start receptacle and fire system activation if fitted ), and an optional integrated fire suppression system .
Downtime during service and maintenance is dramatically reduced on all Elphinstone vehicles through some clever engineering and onboard diagnostics simplifying for service personnel . Large , hinged engine enclosure doors make servicing easy and fast , as do removable floor and side plates . Quick change air filters and 500-hour oil service intervals reduce downtime and keep machines in operation longer for greater productivity . A centralised on-board service centre includes fast fill and evacuation points and points to take uncontaminated fluid samples for analysis .
The WR810 operator cabin is designed to seat three people in comfort with exceptional visibility . In a working environment a three-seater cabin allows for the complete crew to go collectively , rather than deploying an additional light vehicle for personnel transport . The operator cabin can be optioned as fully enclosed with climate control air-conditioning and pressuriser to prevent dust ingress if required . Seat options include a mechanical suspension seat or an active suspension seat for premium operator comfort . The machine controls are ergonomically designed and positioned , allowing the operator to control machine functions with minimal effort , resulting in greater concentration on vehicle operation , with reduced operator fatigue . The transmission control for forward , reverse and gear range is conveniently located for the operator ’ s right hand .
Easy-to see and conveniently located gauges and displays make monitoring machine systems as simple as possible . The system continuously provides critical machine data , and a three-level warning system alerts the operator of any abnormal conditions .
The WR820 is also available with an optional air-conditioned , enclosed cabin . The modular cabin is resiliently mounted on the truck chassis , reducing vibration for greater comfort and a quieter ride . The enclosed cabin features ergonomics for operator comfort , user-friendly intuitive controls and excellent visibility .
