3.0 AVAILABLE OPTIONS
3.1 BI-DIRECTIONAL TORQUE GAUGE LOAD CELL
The Backup Unit comes equipped with a cradle on each side of the unit to handle a bi-directional
circular torque gauge load cell. The load cell needs to be of a compression type no larger than 6 inches
in diameter with a thickness of less than 2 inches.
The Universe bi-directional piston compression load cell is designed to fit and work with all Universe
Backup Units. It is important to ensure the pistons are fully extended prior to any load applied to them
and positioned so that the piston faces the Backup body and not the side frame.
It is important to ensure the torque arm on the gauge face is matched to the torque arm of the Backup
otherwise all readings will be off. If filling the gauge via the fill port (see Figure 3.11), ensure not to
overfill the unit. The gauge should alwa
ys read “0” when not under load.

4.0 HEIGHT ADJUSTMENT AND LEVELING
The Backup U
nit is designed to “float” with the use of two large compression springs in the front, and
two tension springs in the back.
This “float” allows the Backup Unit to move up or down to take up the
vertical movement when making up or breaking out threads.
The rear two tension springs and chain allow the Backup to be kept relatively level with the Tong and
are adjustable.
