The powerful zero-emission drilling rig for anchor drilling with double head.
Zero Emission
The KR 806-3E zero emission drilling rig is the latest member of the World renowned KLEMM KR 806 family, recognized for its advanced technology and maximal performance. Zero emission means to be free from exhaust fumes, and to have a significant reduction in fine dust and noise pollution. The KR 806-3E is ideal for use on construction sites with high standards of decarbonization and zero-emission targets including sites located in urban 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 806-3GS. Stiffness, operational fatigue strength and operational stability have been significantly increased whilst there has been a considerable reduction in mechanical tension. The kinematics, primarily designed for drilling shallow, inclined, deep-set boreholes, now also enable piles to be drilled directly beside the tracks, both to the left and to the right.
Hydraulic system
The hydraulic system includes a three-circuit load-sensing system which uses the successfully tried and tested Load Limit Control and patented Power-Sharing technologies. The mobile control blocks are directly integrated into the CAN-BUS and are extremely responsive. They are self-regulating thus unaffected by temperature and highly precise. The EEP-Package (EEP=Energy-Efficient Power) uses a power and energy management system whereby the motor speed automatically adapts to the respective load and operating conditions. Additionally, the large hydraulic cooler features temperature-controlled speed regulation which further reduces noise emissions.
Smart operation and control
All the drilling rig functions are operated over radio remote control. The functional safety of the machine control system complies with Performance Level C (ISO 13849) which means that it has been designed to be extremely resistant to malfunctions and failures. The drilling rig can also be operated in modes ROM and SPM in accordance with EN 16288. A further safety feature of the KR 806-3E is that it is pre-equipped for the installation of a KLEMM Bohrtechnik interlocking guard.
Maintenance and diagnostics
The already extensive display options and diagnostic tools that are customary with KLEMM Bohrtechnik have been also been expanded. For example, the screens can display the flow regulation of each flushing channel, the drilling depth or the inclination of the mast. All pump circuits are equipped with easily reachable mini measuring connectors. A telematics system with the DataLink Air module is installed as standard.
