Zero Emission
The newly developed KR 806-4E drill rig is the zero-emission solution within the globally popular KR 806 series, recognized for its advanced technology and maximal performance.  Zero emission means to be free from local exhaust fumes, and to have a significant reduction in fine dust and noise pollution. The KR 806-4E is ideal for use on construction sites with high standards of decarbonization and zero-emission targets including sites located in urban, noise-sensitive areas, in tunnels and in enclosed spaces.Smart drive technology
The power train is based on an electrical, permanently energized synchronous machine with a peak output of 180 kW.  For permanent maximum power, a stationary connection to the mains with 1x 250 A and Powerlock connectors is available. Connection to a standard 400 V AC on-site power distributor for hybrid operation ( grid/battery) is very easy with a max. 1x 125 A CEE plug. The actively cooled battery is used to cover peak loads and allows the rig to operate independently to the mains supply. Using its own battery management system, the battery automatically recharges depending on load situation at that time. When configured with battery, an on-board transformer ensures galvanic isolation and the correct electrical network. This allows for a safe operation in all working applications.

Machine kinematics
The kinematics are the same as those of the KR 806-4GM. Stiffness, operational fatigue strength and operational stability have been significantly increased whilst there has been a considerable reduction in mechanical tension. The kinematics have been specially reinforced for the MAG 6.1 rod magazine. They also provide an option for HDI equipment.
