Stronger, Smarter, Safer

• Ammann introduces two new reversible vibratory plates, APR 52/75 and APR 58/75, designed for versatile use in road, civil, and trench construction.

• The machines feature enhanced handling with hydraulic forward/reverse control, a twin-shaft exciter for uniform compaction, and extendable working widths.

• Engine options include powerful Honda petrol and Hatz diesel engines, with low-emission diesel particulate filter variants available.

• Optional ACE compaction control system provides automatic soil-adaptive settings and verifiable compaction results, ideal for rental fleets and varied operators.

• Design improvements reduce maintenance effort, improve air circulation, and significantly lower hand–arm vibration compared to competitors.

Topline Ammann: The New Reversible APR 52/75 and APR 58/75

With the new APR 52/75 and APR 58/75 models, Ammann is launching two powerful reversible vibratory plates that replace the proven APR 49/20 and APR 59/20.Lead

These two new additions to Ammann’s range of reversible plates are true all-rounders for road, civil and trench construction, offering excellent handling, dependable compaction performance and, above all, practical innovations proven in the field.

“Our new reversible vibratory plates set new standards in terms of handling – both forwards and backwards. Comparative data clearly show their advantage over competitor models,” says Thilo Ohlraun, Sales Manager Germany at Ammann Verdichtung GmbH. “Their predecessors, the APR 49/20 and APR 59/20, were the fastest on the market. The new models keep up – and go even further in terms of maintenance, safety and operability, even on difficult terrain.”

The machines have a working width of 450 mm, which can be extended by using extension plates to 75 mm or 150 mm. The twin-shaft exciter unit ensures uniform compaction and allows the operator to change direction precisely. Thanks to the hydraulic forward and reverse control, challenging conditions – such as gradients of up to 30 per cent for example – are easily managed. For particularly difficult spots that require extra compaction, or for precision work in tight areas or along edges, a spot compaction mode can be activated.

“The reversible plates are the entry point into the premium class,” adds Ohlraun.

Powerful, Clean, and Easy to Maintain

Both models impress with powerful engines – either a Honda petrol engine or a Hatz diesel engine, also available with a diesel particulate filter (DPF) for low-emission applications. This makes them especially suitable for compacting narrow trenches and difficult areas. Incidentally, BG Bau currently provides grants for machines that protect workers from excessive exhaust emissions.

The new frame design without an engine cover creates a more uniform look across the APR and APF ranges improving air circulation and maintenance access easier. “Without an engine cover, the machines come with less weight and the motor is much easier to reach – a major advantage on site,” says Ohlraun.

Smart Compaction with ACE

Further refinements to the new APR models include improved lashing points for ten-tonne hooks, a smaller yet powerful battery with jump-start capability, and a more durable wear-resistant V belt. The handle design has been optimised, reducing hand–arm vibration (HAV) noticeably, particularly when reversing. “Our models already have the lowest HAV values in the industry,” explains Ohlraun. “Under identical test conditions, the new machines perform up to 45 per cent better than competitor models.”

For modern site requirements, the optional ACE (Ammann Compaction Expert) compaction control system is available. It automatically adjusts frequency and amplitude to the soil and provides verifiable compaction results. “This makes the reversible virbratory plates APR 52/75 and APR 58/75 particularly suitable for rental fleets and applications with changing operators – and also thanks to their intuitive controls and long service intervals,” Ohlraun concludes.

With these redesigned vibratory plates, Ammann is setting the course for the future of compaction technology – practical, powerful, and built to last.
