Professional manufacturer supply used core drilling rigs

 I.General introduction:
DF-Y-2 Core Drill is up-dated designed according to the development of geological works to meet the needs of users. It is a new type spindle core drill rig. It is applied for engineering geological exploration drilling, hydro geology well drilling and big-hole basic engineering drilling including core drilling with tungsten-carbide tipped and diamond bit mainly.

1. Light in weight, easy relocation.
2. Adopting traversal winch, this will overcome the fault of wire arbitrary intertwine and quick wearing out of the winch laid in length ways.
3. Belt transmission is adopted for the high speed level to make the drill soft in the uneven formation, and reduce the damage to the components and other mechanical failure.
4. In large spindle hole.
5. With wide speed range and large torque moment in lower speed, it is suitable for engineering geological subterranean and water explorations.
6. The rig is stable in relocation and firmly for position.
7. Debuts F3L 912 diesel engine or 22Kw electric motor for your selection.
