Ammann showed range of light compaction equipment at CONEXPO-CON/AGG

Ammann showed its full range of light compaction equipment at CONEXPO-CON/AGG 2020.

Among the product lines on display were:

Rammers

Ammann says its Rammers are so easy to use that operators of all experience levels are able to perform productively right from the start. The reduced-vibration handle lessens fatigue and ultimately serves as a productivity booster. A patented process enables rammer height to be easily adjusted to fit the operator size, another significant comfort feature.

Vibratory Plates

Ammann offers a wide range of Vibratory Plate Compactors that are ready for any situation. The product line ranges from a light 54 kg (119 pounds) to a much heavier 825 kg (1,819 pounds) – with many models in between.

All Ammann plates are easy to operate. Many models are available with choice between a diesel or a gasoline engine.

The Ammann vibratory plates have different exciter systems, depending on their size and needed forces. Ammann says that all the plates offer easy operator control. That includes when changing directions or working on steep grades.

The low-vibration guide handle is isolated from vibration to minimize stress on the operator, allowing for precise machine control and operator comfort. The handle is foldable, a crucial feature when working in confined areas or during transport.

There are three series of Ammann plate compactors.

• APF Series: Forward-moving vibratory plates 54 kg (119 pounds) – 106 kg (234 pounds)
• APR Series: Reversible vibratory plates 100 kg (220 pounds) – 440 kg (970 pounds)
• APH Series: Fully hydrostatic reversible vibratory plates 350 kg (772 pounds) – 825 kg (1,819 pounds)

Unique triple-shaft exciter system for Vibratory Plates

Ammann developed a triple-shaft exciter system for its APH products, the largest plates in the Ammann portfolio. This unique technology with the third exciter shaft makes the machines easier to control while increasing the power and compaction forces.

The system keeps plate movement consistent, which in turn enables smooth travel – even through heavy, cohesive soils – and helps effortlessly overcome steep grades. APH machines can even climb while backfilling saturated areas.

Walk-Behind Rollers

Ammann Walk-Behind Rollers combine two applications in a single machine. The operator chooses whether to utilise a high-amplitude setting for work on gravel/soil or a low-amplitude setting for asphalt and bituminous materials. The necessary water sprinkler and a generous water tank are standard equipment.

ARW rollers offer clearance on both drum sides, allowing compaction work extremely close to curbstones, retaining walls and other obstacles. The hydrostatic-driven rollers are built without mechanical fast-wearing parts such as V belts and a clutch, helping reduce maintenance needs.

The ergonomic guide handle includes the dead man's handle that immediately shuts off the machine if the operator releases his or her grip. In reverse mode, the roller's speed is limited to 2.5 km per hour as a safety regulation to protect the operator.

The hydraulic drive ensures variable speed adjustment and smooth starting/braking action.

Ammann ARR Trench Rollers

Rammax invented the trench roller product more than 40 years ago, and benchmarks have always been set to improve efficiencies. Today, Rammax is embedded in the Ammann portfolio and with its ARR line, Ammann is the only manufacturer to still offer both articulated and skid-steered versions of trench rollers.

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 and ARR 1585 are able to overcome the high moisture content in clays through their extreme compaction energy and the kneading effect of their padfoot drums. The ARR 1575 is the articulated trench roller while the ARR 1585 is the skid-steer body version.

The machines perform effectively and quickly on less challenging soils, too.

Ammann says that the infrared system is perfectly positioned with no dead angles. Integrated solar panels charge the transmitter.

APA Add-On Compactors

The Ammann range of APA Add-On Compactors work safely and efficiently – and in areas other machines can't access. The attachment plates can be mounted on any standard excavator arm and are true champions in terms of compaction forces and compaction speed. The vibration forces of the plates and the compaction pressure given by the excavators let the APA products compact at a depth of up to a metre and work safely on steep slopes or dangerous trenches.

Intelligent assistance systems for more efficient compaction

Ammann Compaction Expert (ACE) intelligent compaction technology is offered on selected light equipment machines. ACE uses intuitive LED signals to keep the operator abreast of compaction progress. Operators also can evaluate when compaction goals have been met, helping reduce unnecessary passes. ACE also helps prevent overcompaction.

ACE is available on larger vibratory APH and APR plates, APA Add-On Compactors and ARR Trench Rollers.
