FAQST 350 Crawler Mounted Drill Rig Machine
The feeding system
It has a large stroke by extending completely when working, which adapts to long drill stem and long casing constructions. It retracts when travel to reduce transportation dlimensions. It adopts cylinder-wire rope speed multiple feeding system with slow feeding mode, which provides slow drilling and fast lifting. With that it ensures good drilling performance and improves working efficiency.
