Courtesy of Machine.Market They work day after day

Volvo's articulated haulers are at work all over the world, round the clock, in increasingly diverse applications. In many cases, they have been chosen for the task because other methods have been tried and simply haven’t worked. Harsh climate, difficult terrain, high demands on availability – these are factors that have influenced the choice of Volvo articulated haulers. Construction of high-speed trains in Europe, work under ground in South America and haulage at an open-cast mine in Africa – these are just three examples from a steadily growing number of applications.

Courtesy of Machine.Market Loading options A hydraulic excavator is the most common, and in most cases, the most efficient loading option. Excavator and hauler are combined so that the body is filled with 3-5 buckets. A wheel loader may be the most efficient choice for loading loose materials. It moves rapidly and can load a hauler quickly with its big bucket. Conveyor belts, silos and other sta- tionary equipment are also excellent choices for loading an articulated hauler. Because the hauler is so easy to maneuver, the operator can quickly get into the right position and just as easily get out with a full load.

The articulated hauler is basically constructed for hauling of earth and other masses. During the years Volvo’s articulated haulers has proven their availability, flexibility and capacity which has resulted in interest in using the articulated haulers in other applications. On this basis, Volvo has developed a range of slightly modified articulated haulers for different purposes.

With its light ground pressure, off-road mobility and maneuverability, it can negotiate on the landfill and dump the garbage at the right place. These features have made the Volvo A25C Container interesting in other applications where the needs are similar.

Volvo A25C Light material A Volvo A25C can be equipped with a larger body than usual. This enables the articulated hauler to carry loads up to 31.4 yd3 as long as the material transported has a density of maximum 1.5 lb/yd3. Volvo A25C Light material is, for example, ideal for transporting coal and other material with low weight but large volume.
