The trailer comes equipped with added stem racks that can hold up to 32 additional drill stems
The TTMT transmission range was tested in a lab with a series of drill stems linked together.
The TTMT pod digitizes the load cell data with an on-hoard microprocessor and transmits the data by inducing an RF signal through the drill stem to the receiver above ground.
The receiver is designed not to hinder the drill stem as it exits from the ground and is automatically loaded back on the drill rig.
Several factors (amount of drilling fluid, drill stem torque) prevent an exact correlation between psi and tensile pounds-force on the pipe end.
This is why it is recommended that bent drill stems be removed from the machine.
When drill stem is not kept within the limits of its torque range, thrust and pullback limitations, and bending radius, metal fatigue may occur resulting in premature and costly failure.
Makeup and breakout of drill stem joints also imposes stress on the drill stem.
