Trucks with licence to lift

Strict environmental specifications and airport requirements to comply with green targets are some of the current challenges in the airport sector. Increased efficiency and improved environmental compatibility are priority objectives for airport operators as they look to the airport of the future. The DOLL ecat series makes a significant contribution to meeting this challenge. As an energy-efficient high-loader, ecat vehicles are not powered by a conventional truck combustion engine, but by an environmentally friendly electric motor instead, thus saving fuel costs and optimising the carbon balance.

Delivering the airport of the future

  •  Zero pollutant emissions (CO2)
  • Reduction in energy consumption and noise pollution
  • Increase in vehicle economy thanks to lower operating costs per kilometre travelled due to greater efficiency in the energy source, maintenance-free electric motors and warning and safety systems which minimise breakdown and insurance costs
  • Greater safety standards thanks to a gentle, smooth approach when positioning the vehicle next to the aircraft with simultaneous parking distance control
  • Simple infrastructure requirements: no driving to filling stations – batteries are re-charged at the same time as refrigeration unit
  • More operator-friendly, improved drive comfort and intelligent driving assistance
