This is an intrinsically safe circuit so “blue sheathed” cable supplied by LSI-Robway is required.
2.3.5.
Anti-Two-Block (Optional Item)
(Wired to Control Unit though an EEx ib Digital Switch Isolating Barrier)
Fix the anti-two-block (ATB) switch mounting pin to the main boom head preferably so that the bob-
weight (when suspended from the switch) can be fitted to the static hoist rope below the rope anchor.
The mounting pin has 2 x 9mm holes. It can either be welded on the boom head section (directly or
via a steel plate), or be screwed by drilling and tapping 2 holes on a suitable location on the boom
head.
CAUTION:
HIGH TENSILE BOOMS REQUIRE PROPER WELDING PROCEDURE
SPECIFICATIONS. OBTAIN SPECIALIST ASSISTANCE WHEREVER
APPLICABLE.
Check that the switch works correctly as the boom luffs throughout its working range. For twin winch
cranes an additional switch can be added and mounted at the rooster/aux winch head sheave.
NOTE: Cut chain to required length suitable for the winch line speed and application. A thread
locking device should be applied to all shackles in the ATB assemblies.
Fix the ATB cable/s through the junction box(es) supplied and route the cable carefully along the
boom (or through a boom cable tray, if available) and boom pivot to the cabin. Secure the cable on
the boom using adequate straps and fixings ensuring that the cable is not pinched or stretched as the
boom moves through its full luffing arc. Wire the cable into the RCI Control Unit (see APPENDIX G,
Cable Gland Installation Instructions for wiring details).
If ATB function is not required, install a wire link between terminal 13 and 14 and terminal 15 and 16
on the ATB barrier (BARD1031D) – (refer RCI System Configuration Documents in Attachments for
wiring details).
