40m Hydraulic Diesel Engine Borehole Drill/Drilling Rig for Engineering Foundation Construction/Wate

1. Rotary Excavator is a kind of integrated Drilling Machine, which can be used in many kinds of bottom layer, having the characteristics of high speed of hole-forming, low pollution and strong maneuverability.
2. A short spiral drill can be used for dry digging, and a rotary drill can be used for wet digging. Equipped with punching hammer, the rotary excavator can be used to drill through the hard strata.
3. It can be expanded at the bottom of the hole, If the drilling tool is used. The rotary excavator adopts multi-layer telescopic drill pipe, which has less support time and low labor intensity.
4. Do not require mud circulating slag and cost saving, which is especially suitable for the construction of urban construction.
5. Hydraulic Oil models are selected according to local climate: 34#, 46# and 68#.
6. After the first time receiving of Rotary Drilling Rig, release diesel and clean the fuel tank. According to the climate, the diesel is added for the same model: -40#, -30#, -20#, -10# and 0#.
7. After 100 hours of all engines work, release and replace engine oil.
8. After 100 hours of all engines work, release and replace the coolant of the water tank.
9. Cummins engine, please timely contact the local service station for the record, so as to maintain it in future. Otherwise all consequences will be at your own peril, when out of warranty time.
Diesel Foundation Site Drilling Rig
When digging a hole, the drill bit revolves around the vertical axis and makes the axial movement. Soil under the torque and axial force of drill bit will be cutting. During the process of working, under the action of centrifugal force and extrusion of the blade, soil are destroyed and brroke up. The formation of soil flows pressure to the pit wall, at the same time along the surface up to ground. When the soil flow moves to the place, where is no barrier of pit wall, the whole excavation process is completed due to the centrifugal force of the broken earth being thrown around the pit.
