Ammann’s new reversible vibratory plate compactors are designed to deliver improved value to the jobsite, including increased speed and an ability to climb grades as steep as 30 per cent.
During field testing, Ammann said its new APR 52/75 and APR 58/75 plate compactors delivered a speed of 29 metres per minute while maintaining handling, manoeuvrability and compaction performance.
“The Ammann APR 52/75 and APR 58/75 outperform rivals in speed, both forward and reverse – an advantage that is supported by data,” said Ralf Brutschin, Global Commercial Manager for Light Compact at Ammann. “The previous Ammann models were the fastest on the market, and these plates can make the same claim. They are also great climbers.”
The re-engineered plates present a new look that was welcomed by customers during testing. The biggest design change is the use of protective tubes to guard the plates instead of hoods, which removed weight from the machines.
“The plates also reflect reduced hand-arm vibration when in reverse,” Ralf Brutschin said. “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.”
The lack of a hood also improves air circulation, which makes it possible to utilize gas engines that could otherwise overheat. A diesel engine with DPF is available for customers who face specific environmental standards or work in confined spaces.
The APR 52/75 and APR 58/75 plate compactors are available in four engine configurations:
- Hatz 1B40 diesel e-start (current EMEA)
- Hatz 1B50E diesel e-start EPA (current US)
- Hatz 1B50E diesel e-start EPA with DPF
- Honda GX390 petrol hand-start
Ammann has also equipped the plate compactors with improved lashing points suitable for 10 tonne hooks and a smaller battery that performs comparably to its larger predecessor. The battery has jump-start capability for charging during longer standing times.
An improved drawbar leads to better manoeuvrability and lower HAV when in reverse, while a new V-belt system demonstrated significantly longer service life in endurance tests.

Both plate compactors have working widths of 450 mm that can be expanded with 75 mm or 150 mm extensions.
The twin-shaft exciter unit continues to be a key advantage for the plates. Shaft positioning enables the operator to effortlessly change directions. The smooth, variable hydrostatic unit allows the machines to move easily in forward and reverse. On-the-spot vibration can be utilized in particularly challenging areas.
The intuitive nature of the APR 52/75 and APR 58/75 ensure even inexperienced operators can perform productively, making the plates suitable for rental fleets. Rental businesses will also appreciate that maintenance costs are low, and intervals between fluid and filter changes are long.
