1.0 GENERAL
The "SHARK" Slickline Measuring Device is a heavy duty two wheeled device
which accurately measures both wireline depth and tension. It minimizes wire
abrasion and fatigue by using a non reverse bend configuration.
The device is designed to be mounted in front of the wireline drum on a spooling
mechanism. Linear bearings in the mount allow it to slide back and forth in front of
the drum so the wire can be spooled evenly. The head can be hung from an
overhead bar or can sit on bars located at the base of the drum. Spooling rollers
and pressure wheels are provided to keep the wire in the wheels at low or no
tension. An optional "turn table" is available which allows the head to be pivoted
90 degrees for shipping protection.
Tension is measured from a load pin which also serves as the axle for the
tension wheel. Since the two wheels are opposite each other, the wire completely
wraps around both wheels. This creates a relatively high signal at the load pin
which provides a very accurate tension measurement.
