GK 200 Crawler Mounted Drill Rig Product Features
A.53*59 drilling rod adopted,high rigidity and strong delivery torque.
the machine is equipped with national patent technology---taper clutch,with characteristic of strong transmission torque,easy operation and free maintenance.
B.for the winch,we use large module planetary gear and add supporting frame,greatly increasing hoisting and braking ability of the winch.
C.vertical spindle are fixed by four groups of bearings to ensure that the rotary machine is rigid enough for gravel layer and other complex geoloical conditions.
D.to equip with the flow 160L/min mud pump so that it will save cost and also make the machine compact,moblie and lightweight.
GK 200 Crawler Mounted Drill Rig Application
1.Construction drilling of the projects e.g. prospection, geotechnical investigation, railway, road, port, bridge,
water conservancy and hydropower, tunnel, well, industrial and civil construction;
2. Core mining exploration, Or exploration;
3. Small hole diameter water well drilling;
4. Geothermal pipe-installing for heat pump;
5. Small-diameter hole foundation piling drilling.
Wear is the most common bearing seat in hydraulic drill accessories?
The conservative method generally adopts machining after surfacing to repair, and surfacing will make the appearance of parts reach a very high temperature, causing deformation or cracks of parts, and obtaining the size through machining will greatly prolong the downtime. Therefore, polymer composite materials should be used for on-site repair, which has neither thermal effect nor limited repair thickness. The abrasion resistance of the product and the concession that the metal materials do not have can ensure 100% contact and cooperation of the repaired parts, reduce the impact and vibration of the equipment, and prevent the possibility of wear.
