The Complete Air Hammer is Packaged With:
All Air Hammer Systems Feature:
Support Pack
The Support Pack is central to the operation of the Air Hammer system; it controls the air flow from the compressor
to the hammer and it introduces the water/lubricant mixture into the airstream at the predetermined volume (GPM).
Downhole Assembly
The complete down hole assembly includes: Bit, Air hammer, Bent Sub, Transmitter housing, Shock absorbing transmitter
assembly, & Drill pipe adapter. StraightLine® has taken special care to isolate the transmitter/beacon from the hammering
action. In the illustration below you will see that the transmitter/beacon is fitted into the inner sleeve and is then
slid into the outer sleeve with low compression springs on both ends which effectively isolates the transmitter/beacon
from the hammering action.
Steering Points
The air hammer down hole assembly features a precise two point steering system. The steering points are 1) the steering face
on the bit and 2) the convex side of the bent sub. The assemby steers by reacting off of the front and rear steering points
while rotating between two clock positions. These steering points are identified in the accompanying illustration.
Control Box
The Remote Control Box is designed to be placed in a location that is desirable to the operator. Once the unit is in place and
connected to power it allows the operator to control the Support Pack from the drill rig's operator station.
