Hydraulic drilling rigs HRFD 32-A

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.

• Safety is a priority and these machines are designed to be safe for operator and underground operations Brakes with spring hydraulic release on all wheels Operator cabin with ROPS/FOPS frame elements ;
• Spring Hydraulic Release Brakes (SAHR) on all wheels;
• Exhaust gas filtration system

• Automatic fire extinguishing system;
• Remote control

• Hydrostatic 4-wheel drive consisting of a variable displacement pump and four separate wheel motors are used, preventing wheel slip and delivering more power to the wheels, improving engine efficiency and economy by 12%;
• The modular design of the machine allows for quick maintenance, which reduces equipment downtime;
• For smooth operation, the machine is equipped with a performance monitoring system that provides real-time data streaming
