Model SP-A-101 combines the features of being self-propelled, which
allows access into restricted quarters, and the ability to be used
as an areial extractor, which allows extraction of bundles at elevations
up to 80' - 90' in the air.
The Model SP-A-101 utilizes
4 hydraulic gear driven motors with their respective rack and pinion
assemblies to exert a pulling power of 80 dead tons. An added feature
of our extractor is that the frame is designed and reinforced to
withstand up to 150 tons of pull, if properly executed, without
damage. This can be exerted by block and tackle. We're confident
our extractors are the most rugged available today. By design the
pinion gears engage the inverted rack in such a fashion as to encourage
proper meshing instead of discouraging it when pull is exerted
of the design combined with the proper materials have resulted in
an extractor that is rugged, dependable, and requires a minimum
of maintenance. Periodic maintenance on the diesel engine located
on the power unit and maintaining the cleanliness of your hydraulics
is virtually all the maintenance that is required
Both ends of the extractor
are able to be steered independently to a radius of 45°. This
allows the extractor to turn in its own length, as well as to virtually
"crab" sideways, allowing access into very restricted
spaces. The pulling frame is designed to be able to flip over allowing
tubesheet to be pulled by a lip on the pulling sled. This feature
keeps overall length to an absolute minimum. Virtually all of the
extractor length can be utilized to accomodate the length of the
bundle being pulled.

that such power is not needed on every bundle you may pull, but
it is nice to know that you have that kind of power available when
needed without having to sacrifice the efficiency and versatility
of the extractor. The speed of the pulling sled is 6' per minute,
when the power source diesel engine is at 1800 RPM.
