Oil Country 4500 Westco 45000 Hydraulic Power Tongs
Oil Country 4500 Manual and Parts List
GENERAL DESCRIPTION
Oil Country 4500 and Westco 45000 are fast and safe hydraulic power tongs for
making up and breaking out 1.315” to 4.75” Model 45000 O.D. tubing 100) O.D. tubing.
Hydraulic power is directed to a manually controlled throttle valve and hydraulic motor unit.
Fluid power input is converted to the rotary mechanical output which drives the tong’s gear train.
The simple, but rugged gear train consists of a planetary type gear box mounted directly beneath
the motor, and a gear reduction system which provides the extra torque capacity. The tong is
suspended in the derrick or mast by a wire line and swung onto the tubing. Tong jaws grip
automatically and the safety guard door closes. Operate the throttle in the forward position, and
the tubing is automatically made up to the required specifications as indicated on the torque
indicator gauge. The tong may also be used for light drilling, cutting, or remedial work.
