INSTALLATION- (
Please read through before starting
)
Ensure that the face onto which the unit is to be mounted is flat, vertical and parallel to the
line of cable payout. The mounting position should allow free uninterrupted payout of the
cable.
The unit should be mounted with fixing brackets in the horizontal plane. An anti-
condensation filter is fitted to the unit close to cable entry glands, this should be at the lowest
point when the reel is mounted.
Weldable pads are usually supplied with the units to provide stud fixings. These pads also act
as stand offs, so that if they are not used for mounting, care should be taken to ensure that
there is sufficient clearance between the reel barrel and the mounting face, to allow free
rotation.
A cable anchor pulley now requires to be mounted at the boom tip, in order to tie off the free
end of cable securely.
Assuming now that the cable reeling drum is correctly mounted, setting up can proceed.
Remove cover from unit and, first ensure that, if fitted, drive gears for potentiometer are
disengaged.
With all cable wound on the reel, turn the reel in the direction of payout about two full turns
or until tension starts to build up. These turns which provide the initial cable tension are
called pre-load turns.
Have an assistant hold the reel from turning and unwind sufficient cable to reach the cable
anchor while boom or travel is at minimum “Tie off cable to cable anchor securely.”
Extend boom or travel machine slowly to the full extent of travel. Before reaching the limit of
travel, haul off cable from the reel by hand, to ensure that the reel will not bind up before full
travel is reached.
Check that at full extension there is at least one turn available at the reel before binding up.
Whilst doing this, keep on turning the reel to bind up and note the number of turns still
available. Also check that at full extension, at least one full turn of cable is on the reel.
Retract boom or travel to minimum extension while observing that the reel is working
correctly. If more tension appears to be required, bearing in mind the turns available, more
pre-load turns may be applied
The reel should now be set up mechanically.
Electrical connections for over-hoist system, (if fitted), should now be made off and secured.
