REA3500 model hydraulic motor Earth Auger

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?

A:Q345.

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.
