Ammann E-Drive Rammer retains power, other key features

The new Ammann eATR 68 Rammer, an electric-drive machine, generates zero emissions and offers a number of other benefits.

The new Ammann eATR 68 Rammer, an electric-drive machine, generates zero emissions and offers a number of other benefits. “This e-drive machine provides better speed and torque control, which translates to more precise and efficient compaction,” said Ralf Brutschin, Strategic Commercial Manager of Light Equipment at Ammann.

Operators are able to meet compaction targets more quickly, reducing the amount of labor required. “That, in turn, means more profit,” said Brutschin. There are also big savings after the sale through improved maintenance. “There are no fuel or oil filters to purchase to dispose of,” said Brutschin. “Time spent on maintenance is significantly reduced, too – as is machine downtime for servicing.” The Ammann eATR 68 offers power that rivals the petrol version of the machine. Both models have stroke heights of 65 mm and percussion rates of 11 Hz. The centrifugal force in the e-drive rammer is 11.5 kN, compared to 13 kN in the petrol version.

Other key features of the e-drive machine: Charging (Ammann’s battery pack charges quickly – and holds its charge, too. The machine can be charged overnight to maximise capacity the next day. If needed, it can be charged for a shorter period during a shift and then quickly return to work); Interchangeable batteries (the same battery pack powers both the Ammann e-plate and  e-rammer – and likely additional Ammann machines in the future. This provides convenience and promotes uptime); Safety (the plate utilises lithium iron phosphate (LFP) batteries, which maximise safety. The batteries and their advanced management system are particularly robust and resistant to high temperatures, overcharging, and mechanical damage). 

Many features of the petrol version have been retained in the eATR 68: Variable speed (a single button lets the operator adjust speed to match the jobsite needs and conditions); Compaction muscle (exceptional design and engineering ensure the rammer’s powerful compaction punch is transferred to the surface, helping the machine meet any jobsite challenges); Precise weight balance (the design and optimal engine position provide exceptional balance that prevents tipping and delivers a host of operator benefits – including effortless guidance and precise control; the ideal balance also spurs the forward movement that boosts rammer performance and efficiency – and ultimately leads to profitability); Low hand-arm vibration values (an optimised handle concept limits hand-arm vibrations to protect the operator and improve comfort and productivity); Open guide handle (the handle design creates sight lines to the rammer foot during the compaction process, providing informed movement around jobsites; the open guide handle enables a secure grip from all sides, even near obstacles); Toolless daily maintenance (no tools are required to access daily service points, ensuring the maintenance is completed quickly); Long life (the toughest jobsites are no match for the machine’s heavy-duty parts and protective casing; contractors and rental businesses appreciate the durability).

Contractors are considering e-drive machines as options for some of the challenges they face. The Ammann eATR 68 Rammer delivers on all these fronts as well: Reducing the contractor’s carbon footprint while creating zero emissions on the jobsite; Allowing bidding on jobs that require e-drive machines; Enabling work in confined spaces with poor ventilation; Supplying an option for sound-sensitive jobsites, including residential areas.

The rammers are part of Ammann’s eMission initiative, an environmentally friendly solution that is integrated into new Ammann products. eMission starts with reduced emissions – and incorporates efficiency, productivity and lower maintenance demands that make jobsites healthier and business owners more profitable.
