Ammann’s eARX 26-2 Light Tandem Roller features a fully electric drive that can operate for up to 10 hours without recharging.
While categorised as a ‘light’ machine, the compactor actually has an operating weight of 2,640kg. “To have a fully electric machine of this size is a breakthrough,” said Vlasta Medek, Ammann’s global commercial manager for heavy compaction.
Because it is not a combustion engine, the eARX 26-2 is extremely quiet during operation. Sound levels reaching the operator station are 46% less than a diesel version.
The powertrain concept eliminates almost all hydraulic components. The ecological impact is also lessened – and total ownership costs significantly reduced – by replacing the diesel engine and its cooling system.
A key point is the advanced 48V battery pack with a capacity of 600Ah (31.5kWh). The pack’s LiFePO4 technology has each internal battery cell independently protected, so the entire pack is flame-resistant which increases safety.
