With two down the hole drills we cover all hole diameters from 92mm – 219mm. The HD 1500D is designed to run 3,5” to 6” hammers while the HD 1600D copes with up to 8” hammers. As an option an ultra large brake out table with an opening of up to 230mm allows the bit to be removed from the hammer on the machine as such.
A heavy duty rotation unit delivers a peak torque of 8.000Nm which is sufficient to run 140mm diameter drill pipes on the HD 1600D. With 7 + 1 drill pipes the HD 1500D and 1600D are both able to work an 30m benches. The unique walk in type service bay and a swing door mounted radiator created a machine which is very easy to clean and to service.
The HD 1600D is designed to work on unleveled benches as well, it has a track gauge of 2.600mm which is considerably more than what any similar model of the competition offers. Both DTH models are running a well proven GHH two stage air end which delivers up to 30 m³ / 1050cfm and up to 30 bar / 430 psi pressure.
An automated drill tube changing system, a digital drill depth and drill speed indicator combined with a spacious silent cab provide an excellent working environment for the operator.
