CFA Drilling Rig E70/22
The E70/22 drilling rig by EVOMAQ® delivers high torque compared to machines typically classified as large-size equipment. Its drilling capacity reaches diameters of up to 700 mm (27.5 in) and depths of up to 22 m (72 ft). Built on an excavator chassis.
A new generation of power and precision: Brazilian technology transforming the jobsite.
High torque of 13,000 kgf.m.
In this model, we’ve hidden a large machine inside a small one!
The EVOMAQ® E70/22 offers torque levels comparable to those of much larger machines, a major advantage that enhances both daily productivity and the rig’s ability to break through dense soil layers.
Designed to operate with two Linde hydraulic motors and equipped with two Brevini reducers, this head delivers a maximum torque of 13,000 kgf.m while remaining compact. This configuration reduces component wear and provides a significant increase in productivity and performance.
The EVOMAQ® Continuous Flight Auger (CFA) system includes a high-tech monitoring computer that generates accurate, real-time drilling and concreting data, displayed through detailed graphs — ensuring reliability and full control for the operator.
As previously mentioned, the EVOMAQ® E70/22 is a large rig disguised as a small one — and this is proven not only by its impressive torque but also by its drilling capacity of up to 700 mm in diameter, offering greater autonomy and flexibility for project execution, all within a total weight of around 27 tons.
To maintain the auger’s alignment during drilling, the EVOMAQ® CFA rig is equipped with a universal hydraulic clamp system suitable for all auger diameters. This design ensures greater safety and ease of operation for assistants working during the drilling process.
Features 360° rotation, maximizing both operational efficiency and safety. Can be built on excavator chassis from KOMATSU.
