Fitting accessories
• Fit the blanking (inspection) plate to the end of each cross-member in the (fixed track) axis.
• Hang the access ramps onto the end of the tracks on the 'drive on' side, and then insert the
retaining rod into the hooks and locate and fit the split pins in position.
• Attach the end stops onto the tracks at the opposite end to the drive on direction. (Fig. 19).
• Fit the blanking plates onto the tracks.
Adjusting the level of the platform
Rest the platform on the latches at about 500mm from the ground and fully slacken the wire ropes by
operating the ‘LOWER’ lever for a short period, after the platform comes to a stop.
By adjusting the nuts on the ladder suspension stud bolts, check that the platform is level:
• laterally, using a spirit level on each of the cross-members
• longitudinally using a spirit level in the centre of a track
CAUTION: WHEN ADJUSTING THE NUTS ON THE LADDER SUSPENSION
BOLTS, CHECK THAT THE RETAINING SCREW ON THE LOWER END OF THE
LADDER RACK IS NOT CLAMPED IN ITS ELONGATED HOLE AND THAT THE
WIRE ROPE IS KEPT SLACK, IF NECESSARY, OPERATE THE ‘LOWER’ LEVER
FOR A MOMENT.
Adjusting the wire ropes
This adjustment is necessary in order to:
• prevent one or more of the wire rope safety switches from operating when the platform is in its
lowest position.
• allow the latches to be engaged simultaneously, by eliminating any stretch in the wire ropes
under load. NOTE: a long wire rope should be shortened more than a short one to
compensate for 'elastic' stretch.
CAUTION: WHEN ADJUSTING A WIRE ROPE NUT, ALWAYS HOLD THE END
OF THE WIRE ROPE FERRULE TO PREVENT THE ROPE TWISTING.
• Lower the platform to the ground. Release the button that unlocks the latches and then the
‘LOWER’ lever, after having pulled on the wire rope in column 4 (Fig. 13) so that the ram is
fully extended.
• Adjust each wire rope end in turn until a measurement of 62 +/- 2 mm is obtained between the
bottom of the cross-member cheek plate and the top of the column base plate. A clearance of
7 to 10 mm is to be obtained between the bottom of the cheek plate and the lower column stop
(1 turn of the nut = 2 mm).
• Position a vehicle weighing approx. 2,500 kg on the platform and raise it to eye level, leaving
it suspended on the wire ropes.
• Measure the dimension 'X' (See Fig. 13) for each column and identify the highest cross-member
end in relation to the ladder slots.
• Raise the other ends by turning the nut on the wire rope end fitting until they are brought
to the same level as the highest end (1 turn of the nut = 2 mm).
• Fit a and fully tighten locknut onto each wire rope.
• Fit the column covers in position.
