Abu Dhabi-based contractor Al Jaber Establishment has taken delivery of 30 Volvo A40D articulated haulers for a project to level areas of desert in the north of the Emirate for irrigated farmlands.
Al Jaber's contract covers an area of 5km by 7km of the Ashoosh Farms project. The work also involves preparation of 98km of service roads and maintenance of 35km of existing roads.
In the cut and fill process, dozers push the material from the dune, which can be as high as 200m above datum, into loaders which dump it on to conveyors for transport to the truck loading point.
Al Jaber is operating a fleet of 140 trucks and haul units which is moving around 250,000m 3of material each day over distances between 1km and 3km. The trucks operate up to 15 hours a day, six days a week.
The all wheel drive of the A40D is proving a benefit on this job since it allows the truck to back into depressions in the fill area, tip the load and then move away. The new fast dump system has also proved beneficial, according to Al Jaber.
Another feature which has come into its own on this project is an oil bath precleaner which extracts up to 90% of dust and sand before it enters the filter, extending its life. Filter change is weekly, according to the manufacturer's recommendations.
The prepared base is equipped by the Emirate's Agricultural Department with water supply, irrigation and fencing and a 100mm layer of soil and fertiliser.
