Product Description

Underground drilling rig for tunneling boom Jumbo Hydraulic rig reliable heavy duty rock drill in tough conditions

Introduction                                                                                                         

Work coverage up to 168 m²
Large tunnel and mining drilling jumbo with direct control,equipped with three heavy duty booms & eagle type high boom base, greatly increasing working coverage. Multiple drifter models used for this machine to meet various needs of customers.




Features                                                                                                              


1. Drifter
The dual buffering HF103 /HF 104 rock drill drifter for the best service life of drill tools.
and lubricating all gear connections to reduce inner pollution of the drifter.
2. Hydraulic feed beam
Heavy duty aluminum alloy feed beam with long service life and high tolerance to bending and distortion.
covered by stainless steel wrapper and lined by synthetic wear resistant pads between moving parts.
3. Chassis
Articulated heavy duty chassis, 4 wheels drive.
Driven by six cylinder diesel engine with low
exhaust emission
Four hydraulic support legs keeping the jumbo stable.
4. Drilling system
Drilling auto control system, with auto collaring & rotation pressure controlling feed, feed pressure controlling percussion & auto anti-jamming.
HANFA unique hole bottom flushing system for cleaner holes.
5. Hydraulic boom
Box type heavy duty boom with multiple coordination to realize precise hydraulic all direction parallel holding.

Others
