Two new add-on compactors from Ammann are more compact and yet deliver more powerful torque.
The Ammann APA 90/110 and the APA 110/110 feature improved compatibility with tilt rotators on excavators. Instead of hydraulic rotators, the new add-on tools utilize a worm gearbox to provide the rotational movement. Worm gear boxes are more compact than hydraulic rotators and provide more powerful torque, too.
Three widths are available: 800 mm, 940 mm and 1100 mm. These add-on compactors are compatible with all standard adapters on the market. The quick coupling system allows them to be connected and ready for action within seconds.
Add-on compactors reach locations that are unsafe for machines and operators, including steep slopes and trenches. They provide high compaction power and quickly process multiple material types. The attachments are powered by host machines, most often excavators.
These two APA Add-On Compactors are built for the 12-tonne to 40-tonne excavator class and for applications where a strong compaction performance is required. Layers as thick as 1 metre can be compacted, providing significant time savings when compared to traditional vibratory plates.
Applications include pipeline construction, residential and industrial developments, backfill, confined workspaces, slope and hillside compaction, cable construction, dumpsite construction and railway work.
Construction crews appreciate the hazard-free operation of the add-on compactors, which allows work from a safe distance. The excavator’s cabin structure provides additional reinforcement, shielding the operator from any falling debris.
Quick compaction
The compactors utilise Ammann’s innovative triple-shaft exciter system, which directs vibratory forces toward the ground and away from the machine. Highly durable rubber shock mounts absorb the vibration to protect the excavator and ultimately the operator.
The attachments’ robust design enables compaction of thick layers. High output quickens the process.
The APA 90/110 and the APA 110/110 have two modes: high amplitude, or low amplitude, that can be adjusted based on whether they are working on thick or thin layers.
The compactor can be equipped with worm gearbox or with a stiff system, where there is no rotation.
