HFR103 Rotary Drilling Rig
- Drilling Diameter: 2500-2600mm
- Drilling Depth:94-103m
- Engine Power:315-345kW
- Max. Output Torque:300-360KN.m
Features
Optimally designed double swing arm lufing mechanism and optimized hinge point position take account of the construction stability and the transportation convenience at the same time.
Dedicated H-type hydraulic retractable crawler chassis for rotary drilling rigs with large-diameter slewing bearing ensures superior stability and convenient transportation.
Imported Volvo engine with strong power effectively reduces fuel consumption and use costs.
The hydraulic system adopts load sensing technology with total power control and limit power control, making the system more efficient and energy-saving. Independent radiator system provides high heat dissipation efficiency.
The proprietary single-row rope main winch of Hanfa effectively solves the twine problem and greatly prolongs the service life of wire rope.
The rotary drive owns normal mode special for soil layers and rock-entering mode special for rock formations, which improves construction efficiency. The autorotation of rotary drive can achieve continuous adjustments of speed in normal mode and rock-entering mode.
Standard centralized lubrication system makes the maintenance more convenient and improves working reliability.
