Touted as the Green Efficiency models, Sennebogen 830, 835 and 840 E-Series purpose-built material handlers have Eco-Mode, which combines reduced engine speed with an automatic idle control and a start-stop system reduce fuel consumption. A new intercooler design with direct mechanical drive delivers maximum air supply, the company says. Cummins engines power the units, although the machines are also available in electric-drive models.
