Tier 3 Engines Require No After-Treatment
Ammann’s new Single Drum Rollers are highly powered and offer significant cost reductions through savings on fuel and fluids. The new ARS 110.1 T3 and ARS 130.1 T3 are powered with reliable Tier 3 engines and follow the valued tradition of high performing, compact machines from the Ammann ARS soil compactor family.
The machines also reflect Ammann’s ECOdrop philosophy, which makes products more environmentally friendly – and in this case profitable, too. ECOdrop focuses on reduced fuel and fluids. With the new rollers, fuel consumption is reduced by 10% (compared to the previous Tier 3 roller). In addition, requirements for hydraulic oil and cooling liquid have been reduced by 16% and 38%, respectively.
“These numbers are significant,” said Josef Dementev. “They add up substantially on the jobsite. Any money saved on these costs goes directly to the company’s bottom line.” The profits are just part of the picture. “ECOdrop makes the machines, and jobsites, more sustainable,” Josef Dementev said. “Reduced fuel consumption preserves a natural resource and lowers emissions. Disposal needs are lessened as well.”
No Engine After-Treatment
The new Ammann ARS 110.1 and ARS 130.1 weigh 11 and 13 tones, respectively. The new Tier 3 machines are dedicated for markets with unregulated engine emissions and replace the previous generation of ASC T3 compactors.
They extend the product portfolio and bring to the market the highest level of operation comfort and safety, combined with unmatched productivity. Due to their compaction power and manoeuvrability, they are perfect fits for mid and large-scale projects such as road and highway, industrial zones and industrial areas. Intuitive control and self-explaining operation are big benefits for those who provide training to newcomers, or for less-skilled operators.
Both the Ammann ARS 110.1 and ARS 130.1 are equipped with proven and reliable Deutz EU Stage IIIA/US EPA Tier 3 diesel engines without any Engine After-Treatment (EAT) components. The absence of an EAT system simplifies service and maintenance and further reduces costs of ownership. Engine power output is 96 kW (129 hp) at 2200 rpm. Engines can run on high sulphur content fuels.
A powerful engine and high-pressure hydraulic system grant excellent traction and exceptional effectiveness. A large fuel tank (310 lt) and low fuel consumption ensure at least 3 working shifts without re-fuelling, reducing costs connected with fuel logistics on the jobsites.
Ammann rollers have excelled on the market for many years, bringing high compaction output for effective jobsite performance. The ARS 110.1 and ARS 130.1 drums are designed and manufactured in-house, which ensures high quality and extreme durability. They have a working width of 2130mm (83.9 inches).
The robust, four-bearing vibratory system hosts a two-stage vibratory system, which generates eccentric forces of 275 kN at low frequency (32 Hz) and 160 kN at high frequency (35 Hz). High value of both amplitudes (1,9 mm high amplitude and 0,85 mm low amplitude) ensures excellent compaction throughout the depth of the layer. The vibratory system is self-lubricated (oil bath) and water cooled, so there is unlimited time for activated vibration and extended lifetime of vibratory bearings for lower costs of ownership.
A smooth drum is standard on both machines. The smooth drum thickness of both models is 25 mm (0,98 inch), which guarantees lifetime operability. To meet all application requirements, the rollers are optionally available with a PD shell kit (2 piece), which delivers the best results on cohesive soils by adding a tamping effect into the compaction process.
Ride and Roll
The proven no-rear-axle concept puts Ammann ARS Rollers above the competition. The lack of a rear axle makes the machine more compact and enables a lower engine location. These two design improvements lower the centre of gravity and improve visibility and manoeuvrability. Those factors, combined with stability, promote jobsite safety. Specifically, they grant better stability – even on steep slopes.
A fully hydrostatic propulsion system makes traction a key differentiator. Each traction element (the drum and both wheels) has its own drive motor and gearbox, optimising the traction forces necessary for safe operation in difficult terrains. Machines are equipped with a flow divider between the wheels (as standard) and can be upgraded by Ammann Traction Control system (ATC). ATC automatically controls power distribution between all 3 drive motors according to exactly defined ratios to maximize machine traction in difficult conditions.
A robust articulated joint provides consistent steering and riding. The steering joint integrates steering and oscillating of both frames and ensures balanced weight distribution and consistent ground contact.
A new operating platform hosts the integrated ROPS structure, which provides essential operator protection. The operator platform is fully insulated from vibration and eliminates most of the vibration to the driver. This feature maximizes comfort during the working shift, protects the operator’s health and increases jobsite safety.
Cab versions are extremely quiet and offer a wide range of advanced technical solutions, such as the elimination of A pillars. This significantly improves operator visibility to machine edges and surroundings. There is 1x1m visibility at all times, and in all directions, around the machine. Windows on both sides of the cab can be opened and allow adjustment of rear-view mirrors from the operator’s seat.
An adjustable steering column with multi-functional coloured display provides all necessary information about the machine’s status – such as working hours, fuel consumption or error codes. All switches needed for machine control are located on the right armrest. Machine control is simple and intuitive – operators can learn to run the compactor in 10 minutes.
Serviceability, downtime and ownership costs are all addressed. Ammann teams from around the world have collected information, and that input has been reflected in the innovative design. In addition, the ECOdrop philosophy makes the machines maintenance friendly and environmentally focused.
The engine compartment is easily accessible, with a robust design that protects all major components during operation. All maintenance and servicing points can be reached from the ground. The compactor is equipped with external draining points for essential fluids such as engine oil, cooling liquids and hydraulic oil.
Onboard diagnostics allow quick troubleshooting, when needed. The multi-functional display shows important information on machine status and indicates any possible issues via fault codes.
The proprietary Ammann ACE system (Ammann Compaction Expert) is available as an option. The system enables easy monitoring of compaction progress for operators and helps them becoming more effective when controlling the compaction process. The CE conformity is optional and proves that the machine is fulfilling European requirements for safe and clean machine operation.
