2013 New Design AKL-A-6A ground hole drilling machines

1.Percussion type drilling rig is one important drilling equipment in foundation construction of pile and borehole. It can adopt to various geological conditions, especially to pebble bedand rock stratum.

2.Percussion drilling rig is more applicable than the other kinds of drilling machines. Meanwhile, when use the percussion drilling rig to drill boreholes, after the hole is formed, there will be a dense layer of soil around the hole wall, which is very useful for stabilizingthe hold wall and improving the carrying capacity of the pile foundation.

3AKL-A-6A drilling rig is very popular in the market currently, all of its components are all installed in the trailer, like electric motor, drive motor, hoist etc., integrate motion.

4.The percussion drilling rig uses the crank link mechanism to change the power's gyrationmotion into alternating motion, through the steel wire rope to drive the hammer bit to do up-and down motion.

5.With the impact effect of the hammer bit's free failing, to break the soil, sand, pebble orrock into pieces, and then use the slag tube or mud pump to clean the slag our of the hole.

(Pls. Note that “Q” for “Question” and “A” for “Answer”)

Q:What is the max. depth and the max. diameter of holes allowed for this drill rig?

A:Theoretically speaking, the 300mm to 1800mm in max. diameter and 300m in the max. depth are available for this drill rig AKL-A-6A. Here please note that the real depth and diameter might be different as per your special local working strata.

Q:How many people do we need to operate this drill rig?

A:Two people is enough for this machine. One is the operator, the other is the assistant.

Q:What kind of working strata is efficient for this AKL-A-6A drill rig?

A:It can adopt to various geological conditions, especially to pebble bed and rock stratum, etc. That it, there won’t be any layer to stop its perfect drilling capacity.

Q:How many hours does it take to finish a well with dia.500 and 100m depth ?

A: It depends onyour special local working strata, especially for your stone formation pressure. If your pressure is less than 400kpa, 12 hours will be enough for this drill rig.
