Fully retract the boom. Extend the payout wire slightly and note the direction of
rotation of the large gear wheel for an extending boom. Release the payout
wire and allow it to retract to its' fully retracted position. Turn the large
aluminium gear, by hand, in the opposite direction to that noted for an
extending boom, until the gear stops. Turn the gear in the opposite direction
(i.e. as if for extending) for ¾ of a turn or three clicks of the clutch. Safely
extend the boom to full extension ensuring continuous operation of the gear
wheel and potentiometer. Fully retract the boom and again check operation.
Refit the recoil drum cover and ensure all mounting nuts are tight.
Route the cable carefully from the recoil drum back around the boom pivot to
the cabin. 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 Display Unit when finished welding.
Notes:
The slip-rings in the ROBWAY recoil drum are designed for use with
ROBWAY Anti-2-block systems and are not for resistive or inductive
circuits such as lights or bells. If you have a particular application that
you feel may be applicable to the slip-ring facility, please contact
ROBWAY for further advice.
Please note also that high tensile booms require proper welding
procedure specifications. Obtain specialist assistance in these cases.
Pressure Transducers
The RCI-1502 System uses two pressure transducers fitted to the hydraulic luff
cylinder/s, one into the bore (force) side and one into the rod (annular) side of
the cylinder to monitor the total forward moment force of the boom for load
sensing.
