together a 25 point package of service offerings. Designed to be a best practice policy document for its dealers everywhere, ideas include machine inspections, which generate repair recommendations to keep the machines in good condition. Other tips include a safety/environmental inspection? Or offering Eco Operator training that helps operators save fuel and reduce unnecessary machine wear? Or engine overhauls and factory remanufactured components that are as good as new but only around 70% of the cost of new? The list goes on. “These services are not necessarily all new,” says Brannemo, “but it is the first time we have packaged this wide range of offerings in a unified manner.”

The modern notion of customer support is a world away from a parts desk with an oily workshop out back. Parts and service now form just one element of a ‘total care’ offering – one wrapped up in soft products, service agreements, known costs and guaranteed machine availability. “Providing parts is still an important aspect of our business,” says Brannemo, “but we want to be a total care supplier, one that has a presence at every touch point of the ownership experience.”

He also warns against cheap, non-OEM parts. “If parts are significantly cheaper then it is generally for a good reason – and those reasons seldom benefit the machine.” “The perception of Volvo being expensive is false,” adds Mark Charland, Manager for Global Marketing Communications for Volvo’s customer support efforts. “We have done a lot of research and have found that in comparison with our competitors we are in a very healthy place when it comes to costs.

“A filter not bought from a Volvo dealer may look the same as a genuine filter but without the assurance of knowing where it came from you can’t be sure it is the real thing. Even a small difference in the performance of a component or filter can reduce performance – or in a worst case scenario – lead to major machine damage and extensive downtime. If you consider that parts contribute on average only between 10-15% of a machine’s operating expenses,” continues Charland, “it’s just not worth the risk to use non-genuine parts when the dangers in terms of under performance, damage and downtime are considerable.”

Volvo has long offered a remanufacturing service that rebuilds components to the latest specifications, incorporating all updates – but sold at a healthy discount off a new component’s list price. Dealers in North America have taken this concept one stage further in the ‘Second Life’ program. Offering a comprehensive

Volvo Penta’s TAD1650VE is a powerful, reliable, economical and versatile diesel engine built on the dependable Volvo in-line six design. This is a well balanced engine producing smooth and vibration-free operation at low noise levels, with high torque.

To maintain a controlled working temperature in the cylinders and combustion chambers, the engine is equipped with piston cooling. The engine is also fitted with replaceable cylinder liners and valve seats/guides to ensure maximum durability and service life of the engine.

The state of the art, high-tech injection and air charging system with low internal losses contributes to excellent combustion and low fuel consumption. The TAD1650VE complies with EPA/CARB Tier 3 and EU stage III exhaust emission regulations. These regulations are met by using V-ACT™ (Volvo Advanced Combustion technology). V-ACT includes a flexible high pressure fuel injection system, an air management system including an internal exhaust gas recirculation device and an enhanced electronic controller

refurbishment package for equipment at their mid-life stages, these machines are brought back to optimum working condition and appearance. Aimed at all haulers and excavators and the larger wheel loaders, there are two refurbishment options to choose from.

One is Restore, which is a thorough overhaul, including a new (remanufactured) engine and transmission, all new filters and fluids, plus critical parts that ensure maximum availability – as well as a thorough clean of the machine, new paint and decals. The Renew option has all the operations in Restore, plus a host of

other options, including (using the example of haulers) the replacement of all necessary hoses, rebuilt axles and differentials, new radiators, hydraulic pumps and cylinders.

All this effort delivers like-new performance for less than 65% of the cost of a new machine.

Promoting new funding solutions for refurbishment options, remote monitoring of machine performance, and pro-actively notifying customers when problems arise is important. Through promoting a ‘repair/replace before failure’ mentality, Volvo helps keep the machine population in peak condition.

The design of the Wassara hammer enables close tolerances between the hole and the drill string. Combined with a highly accurate stabiliser fitted behind the hammer, this helps drill very straight holes. The use of water, which is non-compressible, as the power medium, makes it possible to minimise the gap between hammer and hole walls, since the volume of water carrying cuttings back up the hole is very small compared to drilling with air.

The main direct cost saving, when compared to air DTH, is the lower energy cost. When drilling with water, the consumption of diesel is normally 50-75% lower than when drilling with air. When drilling in dry ground, the difference can be explained by the difference in energy efficiency when pressurising water instead of air. When drilling downward under the water table, the difference increases rapidly due to the fact that the air hammer consumes power to overcome water in the formation.

The drill tubes being filled with water, and very low velocity cuttings being transported on the outside, extends the life of the tubes compared to both DTH and top hammer drilling. At LKAB, where the system has produced more than 12 Mm of drilling, the average lifetime of 89 mm diameter drill tubes is some 30–35,000 m.

There is also great potential for indirect cost
