HWL Drilling Depth 1000m Wheel Type Hydraulic Core Drilling Machine
5C new model full hydraulic core drill rig is advanced it is a typical hydraulic drill rig on wheel trailer, with reference technique of same kind equipments at home and abroad. The drill rig has a reasonable design and superior performance. It is easy for operation and maintenance.
The drill rig adopts full hydraulic driving, tire trail-type, so it is a typical hydraulic drill rig on wheel trailer. The drill head is driven by variable motor with function of two-speed mechanical gear shifts, stepless speed change with an advanced and simple structure. The drill head is fed and driven with a system connecting the hollow spindle and oil cylinder with chain. The system has the function, if the piston rods of oil cylinder moving one certain distance, the drill head moving will double the distance. The mast could be adjusted within the range of angle 0 to 90 degree for its drilling hole with a low center of gravity and good stability of the overall unit. The rig provides operator with a nice field of vision and wide and comfortable working condition. The rig looks pretty in overall structure and embodies the design thought of people oriented. (1) Reliable Performance Basing on the guideline of purchasing the critical auxiliary equipment internationally, the diesel engine, the hydraulic pump, the main valves, the motors, crawler reducers and the key hydraulic spare parts are all adopted famous brands products at home and abroad.
(2) High Efficiency Hydraulic Drill Rig on Wheel Trailer With big torque, high power unit allocation and with reasonable structure design and advanced operation method and 6 meters (19.7 feet) length of drill rod, all these guarantee the drill rig's high operation and performance efficiency.
(3) Environmental Protection With lower polluting emission of diesel engine, professional noise reducing design, the drill rig is fully suitable for urban operation and performance.
(4) Energy Saving Hydraulic Drill Rig on Wheel Trailer Adopting the advanced load sensitive control technique, the drill rig has reduced the power consumption and heat generation to the lowest level. With an elegant outline, compact structure, reliable performance and operation easily, it is the priority equipment to be selected in the full hydraulic core drill rig of present domestic market.
1. Main hydraulic pump, valve and motor are all adopted from famous international brands.
2. Batholithis divided into tyre-drawing (with turning device) or steel track (optional), which is equipped with hydraulic support device.
3. The mast of full hydraulic drilling rig adopted hydraulic powered lift/down, which can be folded to store and transport, with touchdown function.
4. Hydraulic system adopted load sensitivity control with high-position operation platform and orifice operation platform.
5. Spindle coring rig power head feed adopts double-speed driving device with long-range feeding system.
6. Power head rotation adopts single-motor driving with 2 grades gear-box and hydraulic stepless speed change.
7. Orifice of core drill rig is equipped with hydraulic holder, centralizer.
