Driving the Volvo FMX 460 8x4 tipper
In terms of appearance, Volvo FMX 460 does not look any different from the Volvo FMX 440 8x4 mining tipper. BSIV emission compliant, the FMX 460 flaunts a Selective Catalyst Reduction (SCR) exhaust after-treatment system. Most SCR components are away from the naked eye except the AdBlue reservoir between the left front and second wheel. An AdBlue pump is integrated into the plastic tank of 32 to 90-litre capacities. Claimed to require topping up every three days considering the continuous operation of the tipper, the FMX 460 features a day cab with comfortable and ergonomic driver area. Powering the truck is a 460 hp, D13K, 12.8-litre, six-cylinder commonrail turbo-diesel engine mounted on a robust and reinforced ladder chassis. Producing a peak torque of 2300 Nm at 900-1400 rpm, the engine has an I-Shift automated manual transmission coupled to it. Power is routed to the road through two live rear hub reduction axles.
Behind the wheel of the tipper, a sense of sitting higher up is had. Behind the large fourspoke steering wheel is a large rectangular instrument panel. Slide the shifter into neutral, and turn the key. The straight six-cylinder motor comes to life and settles down to an idle. Slide the shifter to ‘A’, release the electronic parking brake on what looks like a thoroughly modern and well puttogether dashboard, and step on the accelerator. There is no clutch. The truck starts moving. A noticeable improvement in refinement and noise is evident at once. The BSIV compliant machine is driver friendly and comfortable. In a desolate mining environment, the air-conditioned cockpit is a pleasant place to be in.
With good visibility ahead, through the large single windscreen, the FMX 460 does not call for much effort to pilot. The overburden at the rear feels a matter of course. The FMX 460 moves away without hiccup. With small increments in speed, the 12-speed splitter and range gearbox with automated gearchanging system begins swapping cogs promptly. With the rev needle hovering on the ‘green’ band of the tacho, the FMX 460 amazes with its ability. A considerable improvement in refinement over the BSIII FMX 440 is evident at once. Having earned a strong reputation for its ability to go deep down into a mine, the FMX 460 further elevates the abilities the FMX mining tipper range is known for.
The Dudhichua coal mine where I had an opportunity to drive the FMX 460 is full of FMX 520 and the FMX 480 10x4 trucks. They operate in severe conditions. Exhibiting strong traction, the FMX 460, in severe operating conditions, impresses with its ability to keep noise and dust out. No wonder, one of the 29 drivers participating in the Fuelwatch Challenge expressed that they were longing to get behind the wheel of their trucks to escape the warm, humid and dusty environment of the mine! On the move, the engine brake of the truck makes for good control. The brakes exert a strong bite when called upon to retard the truck. Acknowledging the advantages had by maintaining good mining tracks, BGR has deployed a good number of water spraying tankers and motor graders. If the diff locks help to negotiate narrow winding tracks with loose soil, the interaxle locks help to carry out the task at hand without interruption. When the going gets tough, the tough get going. Is that what the FMX 460 is trying to convey? I think, it is.
