Equipment width: 1 990 mm 
Min/max tunnel height: 2400 – 4670 mm 
Feed boom: 3,2 m 
Hole size: 38-51 mm 

Reliable electro-hydraulic tunneling drilling rig for digging underground mine workings and tunnels using the drill-and-blast method.

The design uses a combination of a high-efficiency electric motor as the driving force for drilling operations and a diesel engine to move the machine.

HRFD 32-A is designed to work in mines up to 4.5m in height

The compact design, 45° articulation and 44° boom angle give the HRFD 32-a superior maneuverability in its class.
