    Caterpillar, along with Pon Equipment, has unveiled an all-electric 26-ton excavator with a giant 300 kWh battery pack in an effort to electrify construction equipment. They built a prototype in Gjelleråsen, Norway for construction company Veidekke who plan to use 8 of them.

    The company expects that the machine will result in a better experience for its employee by reducing air and noise pollution at construction sites. According to the company, it’s the first time that an excavator of this size, 26 tonnes, has been converted to battery-electric.

    It is equipped with a giant 300 kWh battery pack, which they design to withstand a lot of rough movements. The result is a fairly heavy pack at 3.4 tons. They believe that the battery capacity can enable between five and seven hours of use before needing to charge, which can be done overnight.

    The excavator’s powertrain also includes a 122 kW electric motor, which remains almost silent – though the hydraulic pumps can be heard. Øivind Larsen, Veidekke’s construction director, says the single machine will save reduce their CO2 emissions by 52 tonnes.
