Engineering Core Drilling Rig Machine Full Hydraulic Geological Core Drilling Equipment

Product Description

The mobile tunnel core drilling rig is a compact, highly maneuverable drilling system specifically engineered for extracting cylindrical core samples in tunnel construction and geological exploration applications. Featuring a modular design with hydraulic-powered components, this rig integrates a high-torque rotary head, adjustable feed mechanism, and dual-speed drilling capacity to handle various geological formations ranging from soft soils to hard rock strata.
Equipped with retractable crawler tracks and rotating platform, the rig ensures flexible positioning within confined tunnel spaces while maintaining drilling accuracy . The automated rod handling system and dust suppression unit significantly enhance operational efficiency while minimizing airborne particulates
Hydraulic underground core drilling rig is suitable fro drilling holes for the purpose of mine exploring,also they could be used in surface coring,railway engineering,tunneling,construction and water conservancy project.
Is designed especially for underground 360°drilling work,to drill holes in the tunnel. capable of diamond core drilling and other drilling works.
Features: 
1.The sliding and extending & retracting function of the mast makes it convenient for the bottom of mast to touches the ground or platform, thus the drill rig will be more stable. 
2.The swinging arm and mast can do luffing movement, which satisfy the request of multi-angle drilling. 
3.The core drilling machine system of oatation,feed,pumping and clamping relies on fluid drive.
4.Under bad transportation condition, the main frame also can be disassembled ,easy to transport. 
5.It is light weight, small size, easy operation, with good performance, simple structure and easy to maintain.
