1. The speed of the drill with more series (8) and reasonable speed range (when the engine speed is 1500 RPM, drill a maximum speed of 1170 r/min, the minimum speed of 65 r/min).
And low speed torque is large, the scope is wide.
2. The drill has two reverse speed (51 RPM and 242 revolutions per minute).
It is convenient to deal with accidents.
3. The installed power of the drill is large.
4. The structure of the drill is advanced and reasonable, which is convenient for maintenance, maintenance and repair.
5. The driller is small, light and detachable.
Its total weight is only 950 kg.
It can be broken down into eight parts, with the maximum weight of 140 kg.
It is convenient to move and transport, especially for the mountainous area and water area.
6. The shaft of the drill can be made up to 600 mm long, which is conducive to improving drilling efficiency and reducing the occurrence of accidents such as drilling and drilling.
7. The drilling vehicle is stable, fixed and reliable, and high speed drilling stability.
8. The drill pressure gauge and hydraulic system are combined into one, and the oil-filled shock-proof structure is adopted, and the drilling pressure value is simple, accurate, and long service life.
9. The rig control handle is less, the layout is reasonable, the control is flexible and reliable.
In addition to high speed drilling, drilling rig can also be used for low-speed and large-diameter drilling.
11. In addition to the normally closed hydraulic chuck, the drill can also be equipped with mechanical manual to lower the chuck if necessary.
