Ammann Upgrades Reversible Vibratory Compactors

Ammann upgraded the APR 52/75 and APR 58/75 vibratory plate compactors for faster speeds (1.1 mph) and the ability to climb 30% grades.

Switzerland, Europe - Ammann Group Holding AG., a road construction equipment manufacturer, has upgraded reversible vibratory plate compactors, the APR 52/75 and APR 58/75, offers faster speeds in both forward and reverse, reaching 29 meters per minute (1.1 mph) in field tests. They are also designed to handle grades as steep as 30%.

Mr. Ralf Brutschin, Global Commercial Manager of Light Compaction at Ammann, said, “The Ammann APR 52/75 and APR 58/75 outperform rivals in speed, both forward and reverse, an advantage that is supported by data. This is even more impressive given HAV levels for the previous models, the APR 49/20 and APR 59/20, were already the lowest in the industry. In fact, they perform up to 45% better compared to the competition under the same test conditions. The elimination of the hoods creates consistency with other former redesigned Ammann plates. It also makes the machines lighter.”

Ammann improved comfort with reduced hand-arm vibration in reverse. The APR 52/75 and APR 58/75 have 17.7-inch working widths, expandable by 3 or 5.9 inches. A new design with protective tubes reduces weight, improves access to maintenance points, and enhances airflow.

Improved circulation allows Ammann to offer gas engines for the first time, alongside a diesel engine with a diesel particulate filter for those meeting environmental standards or working in confined spaces. Engine options include Hatz 1B40 diesel e-start (EMEA), Hatz 1B50E diesel e-start EPA (US), Hatz 1B50E diesel e-start EPA with DPF, and Honda GX390 petrol hand-start.

The APR 52/75 and APR 58/75 feature intuitive controls, long fluid and filter change intervals, and a twin-shaft exciter for easy direction changes. A variable hydrostatic unit ensures smooth movement, while on-the-spot vibration is ideal for challenging areas.

Other new features include improved lashing points designed for 10 metric-ton hooks, a smaller battery offering comparable performance to its larger predecessor and featuring jump-start capability for longer standing times. Additionally, the drawbar has been enhanced for better maneuverability and lower hand-arm vibration (HAV) when in reverse, while the V-belt system has been improved for a longer service life.
