Large description

Engineering and Design: Leadership in Extreme Terrains.
The S12 Allroad has been developed to push the boundaries of what is possible in forestry and riverbed management. Its design features superior leg mobility, enabling a world-class wading depth of 2.45 meters—making it the definitive tool for river maintenance and marshy conditions. The safety cabin is ROPS and FOPS certified, featuring assisted glazing and a high-intensity LED lighting system to ensure total protection and visibility for the operator in any environment.

Power and Performance: Perkins Tier V Power.
At the heart of the S12 is the 148 hp (110 kW) Perkins 1204J-E44TA diesel engine, fully compliant with strict Tier V / Stage V emission standards. This engine provides massive power reserves for intensive multi-functional carrier applications. To maximize autonomy in remote locations, fuel capacity has been increased to 390 liters. Additionally, the triple-circuit cooling system with a reversible fan ensures optimal performance even under extreme workloads.

Control and Precision: Cutting-Edge Hydraulics.
The machine utilizes an advanced Bosch Rexroth LS/LUDV triple-circuit hydraulic system that distributes flow independently of the load. Operation is handled via ergonomic joysticks integrated into the premium KAB air-suspension seat. For attachment versatility, it features an adjustable Circuit I (0–150 l/min) and a Circuit II (up to 40 l/min), both operating at pressures up to 320 bar, allowing for millimeter precision when managing processor heads or forestry grapples.

Fleet Compatibility:
The Kaiser S12 Allroad is designed as a high-flow multifunctional carrier:

  • Forestry Attachments: High-performance processor heads, mulchers, and wood grapples.
  • Civil Engineering Equipment: Hydraulic hammers, clearing buckets, and winches (40 l/min hydraulic preparation).  
  • Load Capacity: 111 kN breakout force and a lifting capacity of up to 9,500 kg at 3 meters.
