INSTALLATION OF WIRE CABLE & HARDWARE
ASSEMBLY OF TYRE BUFFER AND CABLE
Note: for the following operation, aluminum zip up scaffolding must be used
8. To fit the cable (A), thread the plain end through the End Crossrail (item 2). Fix the cable eye into the Fixed End Bracket using a
M20 x 60 Bolt with Nyloc Nut.
DO NOT OVER TIGHTEN THE BOLT AS THIS MAY CAUSE THE END FIXING TO PINCH THE CABLE.
9. Lay the cable (A) in the general position in which it will be installed ensuring no kinks or bends are formed.
10. Thread the Cable Runner (B) onto the cable.
11. Thread the second Tyre Buffer Assembly (C) onto the cable.
12. Thread the Cable (A) through the Crossrail with Winch (item 4) and onto the Ratchet Assembly, clamp in place using the grip
fitted to the Ratchet Drum.
13. Slacken the locking screw on the ratchet and pawl and tighten the cable by rotating the cable drum with a 20mm diameter
Tommy bar. Any smaller has a tendency to crease the take up drum when subjected to pressure. Ensure the cable is wound
neatly around the ratchet drum.
14. Attach the Button Seat with the attached chain to the Cable Runner. Check the distance between the seat and cable is at least
2100mm.
15. When the dimensions shown on the side elevation on page 5 are achieved, lock the pawl in place using the locking screw.
NOTE: It will be necessary to check and adjust the cable tension during the first few days or weeks of use. This is quite normal and
is due to the initial stretching of the cable. Once the cable has settled further adjustment will not normally be required, but the
dimensions given in these instructions should be checked during routine maintenance and any adjustments made as required. The
cable sag, therefore seat height, is tempertaure dependent. The maximum and minimum dimensions given apply at a reference
temperature of 15°C.
