Telescopic Boom Length Sensor
Fix the recoil drum and pay-out cable guides to the side of the main boom.
Route the cable carefully from the recoil drum back around the boom pivot to the Control Unit. 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.

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 may be supplied 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 is required to be mounted at the boom tip in order to tie off the free end of cable
pulley. Following correct cable reeling drum installation, setting up can proceed as follows:
•
Remove cover from unit and disengage the drive gear from turning the potentiometer.
•
With all cable wound on the reel, turn the reel in the direction of payout about three 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 prevent 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, feed 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 to minimum extension while observing that the reel is working correctly. If more
tension appears to be required more pre-load turns may be applied.
•
The reel should now be set up mechanically.
•
Electrical connections for the hook over-hoist system (ATB) should now be made and
secured.
•
Freely rotate the potentiometer in the direction of retracting boom until you feel it come to its
internal end stop (do not apply pressure). Rotate outwards 1 turn and then re-engage the
gears.
Pay-Out cable
With the pay-out cable attached to the boom tip stand-off bracket, select positions for the intermediate
cable guides provided, one for each telescoping section and one or more for the main boom allowing
2-3 metres between the drum and the nearest cable guide. Measure the distance from the cable to
the sides of the booms, record lengths and mark the positions for the guides. Cut and weld the guides
to the boom after removing the cable. Refit the cable through the eyes and anchor to the post using
the clamp provided. Adjust the position of each eye so that the cable passes through just touching the
top of the ring. When booms deflect and pads wear the cable will take up a lower position in the eye.
Stainless steel cable ties are also supplied with the installation kit and to be used where required.
