Petol U8184 Hydra-Tork Description
The U8184 Petol Hydra-Tork unit was designed for making up and breaking out downhole
tools. It is rated for operation on 4” to 14” diameters with a maximum working load of up to
95,000 ft-lbs depending upon diameter. See the table on the following page for specific
torque ratings. The unit may be operated in any position (horizontal or inclined) and is
totally portable.
The Petol Drill Pipe Tongs are adjusted to the different diameters within their range by
adjusting the chain screw nut for fine adjustment and by adding or removing sections of
chain for the coarse adjustment.
The U8184 also offers the following features:
The tong cylinder and backup tong are mounted on separate tracks for switching from
make up to break out. The tong slides utilize lead screws for adjusting the position of the
tongs. The lead screws are powered by a hydraulic motor. The tongs are raised and
lowered by an auxiliary lift handle (included).
Two adjustable vee-saddles mounted on the hydra-tork base for support. The vee-saddles
are also mounted on a track for easy adjustment.
The unit can be operated with any commercially available hydraulic power unit capable
of delivering 5000 psi pressure.
