Soil Stabilizers for Tractors
Available in the following versions: STABI/H, STABI/H/HP 

The STABI/H is FAE's soil stabilizer for the most demanding professionals. It operates up to 56 cm deep and works with 300-500 hp tractors. The STABI/H is designed to prepare ground for building roads, highways, railroads, parking lots, sports complexes, office parks, industrial plants, and other infrastructure. The exclusive variable geometry chamber allows the rotor to penetrate the soil using the movable frame, which is hydraulically adjustable with extreme accuracy right from the tractor’s cab. Compared to a traditional machine, there is less traction stress, which means a lower power demand and less fuel needed.

Water Spray System

The Water Spray System has the dual function of cooling and mixing.
The cooling function, useful when the machines work as an asphalt cutter (see multi-task machines), has the advantage of limiting the temperature of the rotor and teeth in contact with the asphalt, preventing it from overheating.
The mixing system, on the other hand, is useful in stabilization operations (see multi-task machines and stabilizers) in which the soil and the stabilizing agent are mixed with water.
In fact, at this stage, the addition of water to the mixing chamber improves binding between the stabilizing agent and the soil, optimizing the result of the consolidation work.

Variable geometry chamber

This technological solution, which is one of a kind in the industry, allows the ground to be penetrated with the rotor alone. The mobile rotor can be hydraulically adjusted from the tractor cabin. The chamber has a variable volume—the greater the working depth, the greater the volume of the chamber.

Compared to a machine that plunges the frame into the ground, the variable geometry chamber reduces traction stress, which decreases fuel consumption and increases operating speed, saving time as a result.

Full Control System

The Full Control System is a top-of-the-line system with electronically adjusted nozzles, a self-priming hydraulic pump, proportional valves to adjust the water flow and a control display unit for settings, diagnostics and the machine’s operating status.

Reduction gear transmission

Reduction gears are an alternative to traditional belt or chain transmission systems. Because the technology is so compact, it provides better power transfer to the rotor and requires less power for traction. A reduction gear transmission provides optimal stability with less maintenance — the perfect solution for handling very high torque.

Rotor with built-in transmission

The rotor with built-in transmission on the STABI/H is an innovative solution designed by FAE for maximum stabilization. The placement of the rotor and the transmission on parallel axis helps the rotor achieve superb working depth, without driving the frame into the ground. This technological solution boosts productivity and decreases power requirements, which also helps with fuel consumption.
