About the EK160USM

The EK160USM is a specialized machine designed by CZM for the foundations of Transmission Lines. It has a special parallelogram, where the tilt cylinders face down, allowing it work under very low overhead (20ft). The rotary has a large inner passage which allows the use of a robust 6 element kelly bar, drilling down to 65ft at full torque. It can be equipped with a self erecting counter weight for easy set up and brake down.
