The S12 4x4 represents the latest generation of KAISER mobile walking excavators with all-wheel drive. It sets new standards in performance and efficiency. The undercarriage, which has been specially designed for all-wheel drive, and the highly variable hydrostatic all-wheel drive give the driver outstanding mobility. The hydraulically adjustable terrain pads ensure optimal stability.
No compromises on power and technology
ELIS - The revolutionary hydraulic system
The exceptional performance of the new generation of mobile walking excavators is achieved with KAISERtronic in combination with the newly developed hydraulic system known as ELIS (Electronic Load-Independent System). KAISERtronic optimises the vehicle’s operational and travel features. ELIS enables the driver to actively control the priority and performance of key functions via the display in order to adapt the mobile walking excavator to suit specific working conditions.
The system can calculate the ideal hydraulic power at any given time thanks to the constant communication between all components. The result: maximum power exactly where it’s needed along with higher speed and reduced fuel consumption.
Stage IIIB emissions standards and more engine power
At the heart of the S12 4x4 lies a Perkins diesel engine with high power and high torque levels plus the option of either a 110 kW or a 129 kW version. Its powerful torque capabilities up to 750 Nm at just 1400 rpm enables outstanding, efficient performance from the hydraulic system. The integrated diesel particulate filter meets Stage IIIB of the European emissions standard.
