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 infinitely 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 impressive 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 characteristics. ELIS enables the driver to actively influence the priority and performance of key functions via the display in order to adapt the mobile walking excavator to suit prevailing 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 at the point of need plus higher speed with reduced fuel consumption at the same time.
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. The huge torque of 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.
ROTOline – when performance counts
The ROTOline hydraulic circuit is designed for very power-intensive attachments. A separate hydraulic pump supplies the circuit with up to 220 l/min. The flow rate can be individually set with the tool management system.
Innovation award for design and functionality
The intelligent design of the latest generation isn’t just visible – it’s also palpable. The cab and superstructure form a perfectly coordinated whole. The new walking mobile excavators reveal a consistent focus on dynamic and at the same time functional design of every element of the vehicle.
