Safety & Quality with tradition

H. Anger's Söhne - Drilling and well construction company - since 1863



HAS B4 is a robust and automotive drilling rig and the largest one in Anger’s well drilling fleet. Due to additional units this rig can be used for a variety of tasks. Anger’s employs this rig for several drilling techniques such as flush drilling, air-lift procedures and core drilling.

It is not only this variability that enables our clients to plan their projects under best conditions: also the rig’s integral on-the-job safety and protection against noise and explosions as well as its high torques make it perfectly fit for the respective tasks. Since HAS B4 is able to use casing diameters of up to 558 mm, it is the ideal drilling rig for the construction of large wells.
