Ammann Group, Langenthal, Switzerland, launched its ARR 1585-2 trench roller in January. The ARR 1585-2 offers an all-wheel drive and skid-steering system. The articulated steer trench roller is equipped with four independent drive motors—one for every drum side. This innovative configuration enables 360° on-the-spot turning capability, which is similar to that of a compact skid-steer loader, according to the manufacturer.
The machine’s centralized vibratory system, positioned between the drums, delivers uniform compaction. A high-performance, single-stage vibratory system generates compaction output of 75kN with amplitude of 0.063 inch (1.6 mm). The system also provides consistent vibration frequency of 33Hz.
Two working widths enable the roller to fit into tight spaces or work in open areas, too. The reduced base operating width is 25.2 inches (640 mm). For larger or less constrained job sites, optional drum extension kits expand the working width to 33.5 inches (850 mm), increasing surface coverage and compaction output. The ARR 1585-2 is engineered with a robust four-motor drive system that delivers maximum traction and control across all terrains, according to the manufacturer.
Ammann developed a technologically advanced remote-control system for operation, designed to protect the operator, other workers and the machine itself. The system uses two main control signals: infrared and 3D-LF technology. The remote control is powered by an exchangeable battery that can be charged on-board or externally. A full charge lasts for at least 16 hours of intense machine operation.
It features a water-cooled Kubota D1105, 12-horsepower, diesel engine that meets EU Stage V and U.S. EPA Tier 4f emissions standards.
Other key features of the new ARR 1585-2 include:
- A fully welded frame for protection of components.
- Hoods that shield powertrain components, then open toward the center of the machine for improved access.
- A shift from a mechanical throttle to electronic RPM control for precise load management and smoother operation.
- A water-cooled engine that reduces the volume of hydraulic oil required by 62% when compared to the previous generation.
Each Ammann ARR 1585-2 can utilize optional Ammann Compaction Expert (ACE) technology to increase productivity during the compaction process. ACE is a proprietary, relative measuring device that provides continuous information about compaction levels and displays progress in real time, indicating when maximum compaction has been achieved.
