LANGENTHAL, Switzerland – “Technology” might not be the first word that comes to mind when you see a compactor at work.
But perhaps it should.
The technology built into Ammann compactors is the driving force behind quality, production and cost savings. It can be the difference between a job that loses money – or turns a nice profit.
Ammann Compaction Expert (ACE)
Ammann compaction machines – which include heavy asphalt and soil compactors, as well as light equipment such as rammers, vibratory plates, add-on compactors and trench rollers – utilise intelligent technology to ensure all goals are met.
One key technological advance is Ammann Compaction Expert (ACE), which helps operators confirm that compaction has been achieved before moving onto another area of the jobsite.
ACE is available on soil and asphalt compactors and generally used on large projects where quality goals are essential, such as airport and highway construction.
What makes ACE even more unique is its availability on smaller compaction machines, too. That includes Ammann APH and APR Vibratory Plate Compactors, APA Add-On Compactors and ARR Trench Rollers.
ACE is modified based on the type and size of the machine. A version called ACEforce is utilised on heavier machines and ACEecon on small reversible plates.
ACE improves quality by verifying compaction goals have been met – and by preventing overcompaction, too.
In terms of production, ACE guarantees time is spent compacting the areas that need the most attention and moving beyond the spots that don’t. This puts an end to unnecessary passes of the machines, providing efficiencies that can have a significant impact on profit. Eliminating passes results in savings on labor, fuel and machine wear. It has beneficial effects in terms of service and maintenance, too.
Oscillation is another technologically advanced productivity tool. The process, utilised by heavy soil and asphalt compactors, eliminates about 90% of the stress on materials when compared with a typical circular vibratory system. This is important when compacting on bridges, over sewers and utility lines and near buildings where a conventional vibratory approach can cause damage.
Oscillation uses less force but distributes both vertical and horizontal energy, essentially massaging the aggregates into place. The drums maintain constant contact with the ground and deliver both static and dynamic forces.
Compactors with oscillation can bring substantial benefits to jobsites. In asphalt applications, they are able to work on hot mats sooner than traditional rollers, and they are able to stay on cold mats longer, too. This greatly expands the compaction window, essential for time-pressed crews.
The oscillating rollers are also great fits for sealing asphalt joints. The massaging motion of oscillation supplies enough energy to break down the hot asphalt – yet does not damage the adjacent cold mat.
When working in soil applications, the compactors prevent damage to sensitive structures and overcompaction.
The Triple-Shaft Exciter System
APH Hydrostatic Vibratory Plates utilise Ammann’s patented triple-shaft exciter system. It provides a big advantage, delivering industry-leading climbing ability and compaction output for the APH products – the largest plates Ammann offers.
The triple-shaft system eliminates erratic movements, allowing hydrostatic vibratory plate compactors to travel smoothly, even through heavy, cohesive soil. The triple-shaft’s unique, consistent movement enables effortless climbing over obstacles or while compacting backfill materials with high moisture content. This is done without the usual suction effect, which can leave competitors’ plates at a standstill.
The ability to easily handle and manoeuvre the plates is particularly helpful when the use of low frequency/high amplitude is required.
All these technologies create advantages across the Ammann compaction product range, from light equipment to the heaviest rollers. The benefits add value to the jobsite – and ultimately boost profitability, too.
