Hz-200YY drilling rig is mainly used for civil wells and earth temperature central air-conditioner, geological general investigation and exploration, road and tall buliding foundation exploration, kinds of hole in concrete structure, river levees, subgrade grouting hole drilling and driect grouting, etc.
APPLICATIONS:
This drilling machine is newly designed and manufactured according to the requirement of foundation engineering, suitable for drilling medium mini-type grouting hole of building, skyscraper, dam and harbor and drilling water well.
FEATURES
1. Mast structure, top-drive head can move down or up along with, strength and rigidity
2. Large torque, compact structure, easy to move
3. Top-drive head is equipped with hydraulic chuck, drilling Efficiently.
4. Reasonable arrangement, easy to operate, smooth and quick.
5.53x59 drilling rod adopted, high rigidity and strong delivery torque.
6. The machine is equipped with national patent technology-taper clutch, with characteristics of strong transmission troque, easy operation and free maintenance.
7. For the winch, we use large module planetary gear and add supporting frame, greatly increasing hoisting and braking ability of the winch.
8. Vertical spindle are fixed by four groups of bearings to ensure that the rotary machine is rigid enough for gravel layer and other conplex geological conditions.
9. We are the first ont to equip mud pump with the flow 160L/min in China so that it will save cost and also make the machine compact, mobile and light weight.
