REA20000 Excavator Earth Auger

The gear box is made by ourselves with high precision, low noise, less worn out so have a long service life.
Rock bit is like cone shape, with sharp rock teeth, it has strong drilling and it 's easy to dig into the ground, suitable for some hard soil, such as frozen soil and hard soil.
For the tungsten bit, it is like a fish tail shape, and the tungsten teeth are flat, and easy to move earth. It is suitable for some relatively soft soil, such as loess, clay, backfill and so on.

Auger Drills/Earth Auger Specification

The efficiency mainly refers to the rotating speed whicj according to the oil flow of the excavator. Different working conditions and the proficiency of operators also affect it . 

We have a client who can dig 1,500 holes in a day. His excavator is 6 tons with 350mm diameter and 500mm depth.  And There is also a customers use 7 ton excavator with diameter 700mm & depth 1.8m, just 100 holes within 8 hours.

Auger Drills/Earth Auger FAQ

1.Q:In which condition, auger will craze?

A:Wrong operation will lead auger crazing. Auger should be vertical to the earth when operation. Big type auger drive has reinforcement measure to protect auger.

2.Q:Will the screw blade drop out?

A:No, we haven’t met this condition so far.

3.Q:What’s the gear box used for in the auger drive?

A:The planetary gear is used for transmission. Gear box is used for slowing down the speed of motor.

4.Q:In which condition, earth auger can work most efficient?

A:Efficiency depends on rotate speed. Rotate speed depends on oil flow. Oil flow depends on the excavator pump.

5.Q:In common earth condition, how many holes can be dig in 1 min?

A:Different earth condition has different answer. It depends on the oil flow and pressure, whether the earth loose. For example, it takes 30s to dig a dia 300, depth 1.5m hole in loose earth.

6.Q:How long should change the auger teeth?

A:It depends on the earth condition and working time. According to customers’ feedback, it would be 6 months in loose earth and 1-3 moths in soil with small stones.

7.Q:What’s the space between two screw blade?

A:It depends on the auger type and the outer diameter.

8.Q:What’s the material of screw blade?

A:Q345 alloy steel.

9.Q:Why the output shaft of REA2000-4500 is round, and REA5000-25000 is square?

A:Large type of auger drive has bigger torque. Square output shaft can increase the friction and hard to slide.

10.Q:In which condition, the auger drive won’s work.

A:The hose was not connected correctly. The excavator problem. The motor problem.

11.Q:How about the warranty?

A:We provide 18 month warranty for our auger drive.(Under the correct operation)

12.Q:How many teeth does S4,S5,S6 auger have?  According to diameter of the auger?

A:Yes, according to the auger’s diameter.

13.Q:Why don’t fully weld between screw blade and auger?

A:Because fully weld will make the auger deformation.

14.Q:Will the teeth holder be deformed.

A:It will be worn but won’t be deformed.

15.Q:What’s the material of the teeth and what’s the technology?

A:The material is tungsten and the technology is forged. 

16.Q:How many oil seal does a auger drive have. How long should change the oil seal?

A:4 oil seal. It don’t need to change in general.

17.Q:Oil seal must be changed by manufacture? Or customers can change it by themselves?

A:All the oil seal are normal. You can change it by yourself.

18.Q:Why do the auger drive leak oil?

A:There may be some problems of oil seal.

19.Q:What kind of machine can auger drive be installed?

A:Excavator, crane and skip steer loader.

20.Q:What’s the material of the pin hitch?


21.Q:Why the thickness of screw blade is different? What’s the thickness of central pole? Why the thickness of central pole is different?

A:Because of different type, big torque will make the auger broker.

The thickness of central pole: S4 6mm, S5 8mm, S6 12mm.

22.Q:Why don’t make auger longer, a 2-3m long?

A:We can do this, but it may not be lift up.
