INNOVATION
Talisman Hire Wadeville has become the first tool hire company in the country to acquire a remote-controlled articulated roller, designed specifically for trench compaction. The ARR 1575 is an articulated trench roller that provides perfect ground contact and optimal compaction. The machine and its padfoot drum provide results where other compactors have failed. Its ability to work in cohesive soils can prevent the need for soil removal and replacement, providing a significant cost-saving. Two steering cylinders help make the ARR 1575 responsive and precise, while the oscillation feature provides excellent stability on uneven surfaces of ditches. Morné Venter of Talisman Wadeville says that apart from the obvious safety benefits of having the remote-controlled roller in the trenches, the rental opportunity provided by Talisman Hire Wadeville allows contractors to dramatically speed up trench

The two different settings of amplitudes and compaction performance also enable varied machine usage on construction sites. SAFETY FIRST “We purchased this machine to address the need for faster, safer trench compaction and to eliminate the need for multiple workers in dangerous, deep excavations. In terms of productivity, it easily replaces a dozen or more men using rammers and the quality of compaction is simply incomparable,” says Venter. “For example, where the standard width of rammers is in the region of 300mm and achieves up to 12Kn of compaction force, the padfoot
rollers of the Ammann ARR1575 with a width of 850mm can achieve up to 75Kn of compaction force with great accuracy. A clearly visible compaction level indicator also gives the operator a visual representation of compaction progress and eliminates the risk of over-compaction, thus saving time. “Trench rollers, also called multipurpose compactors, perform well in cohesive soil types such as clays, that can be very difficult to compact. The ARR 1575 is able to overcome the high moisture content in clays through its extreme compaction energy and the kneading effect of its padfoot drums.
