The HD90MKIV group of machines are very versatile medium range drills that have good articulated kinematics for the boom and undercarriage.
This makes it a highly flexible machine when holes have to be drilled at various angles and different positions. They feature oscillating tracks, a bearing turntable, and a choice of drill heads or hydraulic drifters for any type of job. They are especially suited for anchor drilling using drifters, and other slope stabilization jobs. They have powerful traction drives that enable the machine to traverse gradients of over 30 degrees.
