110’ Length Sensor – (DRURW33LAA)
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 pay-out. The mounting position should allow free uninterrupted pay-out of
cable.
 The unit should be mounted with fixing brackets in the horizontal plane and be parallel with
the crane boom. An anti-condensation filter unit 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 must 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 the potentiometer are
disengaged.
 With all cable wound on the reel, turn the reel in the direction of payout, say two full turns,
when tension will be found to build up. These turns are called pre-load turns and provide
for initial cable tension.
 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.
 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, & luffing fly angle sensors (where fitted),
should now be made off and secured.
 Potentiometer gear for length sensing may now be re-engaged into mesh with the driver
gear. Ensure that all gear-locking screws are secure. Normally it is necessary to ensure
that the boom is fully retracted or, that the machine is fully home. The pot gear should be
turned by hand, in the direction driven when winding in cable, until the end stop is felt. Turn
gears forward one quarter (¼) turn, and allow to engage into mesh. Further adjustments
will then relate to the length indication system.
 Route the cable carefully from the recoil drum back around the boom pivot to the cab. Fix
the cable to the boom and turret using adequate fixings ensuring that the cable is not
pinched or stretched as the boom moves through its full luffing arc. Only connect the cable
to the Control Unit when finished welding.
