GY-300A rig is a shallow hole core drilling rig, it is not only applicable to the alloy, diamond-based large and small diameter core drilling, but also for engineering geological survey and construction, hydropower projects, roads, Engineering railways, ports and other areas of construction. Rig has the following characteristics: 1, the rig has more (8 files) speed of progression and reasonable speed range. 2, wide low speed, high torque, range, except for high-speed drilling, but also for low-speed large-diameter drilling. 3, with two tranches reverse speed, when dealing with labor-intensive small hole accident and safety. 4, big rig installed power, optional diesel engine or electric motor. 5, advanced rig structure, reasonable layout, flexible operation, reliable, easy to maintain, maintenance and repair. 6, drills, small size, light weight, removable good. 7, vertical drilling rig to carry out the process as long as 600mm, help to improve drilling efficiency, reduce the occurrence of sticking and other accidents. 8. Move the car stable, fixed simple, reliable, high-speed drilling and good stability, so that a large open orifice distance. 9, drill press table using oil-filled shock structure, WOB value scale is simple, precise instructions, instrumentation and long service life. 10, rig chuck hydraulic cylinder pin type, clamping reliable, not to hurt the initiative to drill.
