Switching to High-Speed Operation
Once tension on the pull line has stabilized at low speed, you may shut off
the motor, and as it is idling down, shift the motor gear box for high-speed
operation. On the Standard and Plus pullers, stop the puller and use the
clutch knob on the side of the power pack assembly to change the speed.
(See Figures 10 & 11)
Recommended Working Load for Rope
The recommended working load is determined by taking the average
tensile strength of new rope under laboratory conditions and dividing by a
factor to determine the maximum load that should be applied to the rope.
The factor varies with type of fiber and construction. This factor usually is
sufficient to assure you of a comfortable safety margin, however, there are
exceptions.
Synthetic fibers are susceptible to degradation and damage in many ways
that are not controllable by the manufacturer. Therefore, it is imperative
that the rope be inspected before use. If it shows signs of excessive wear
it should be replaced.
