Attach the lifting device to the trolley in
order to avoid having to lift and attach
when gantry is fully erect.
With the help of 2 (or 3) people, scissor
the beam and A-Frame into position
(using the first bolt as a hinge until
A-frame assembly perpendicular to beam)
Repeat the scissor activity at the opposite
end of the gantry - Steps 16-18
Tighten all bolts to 27 Nm (20 ft lbs) or until spring
washers are fully depressed.
If raising the beam height – leave the two height
adjustment bolts loose on each upright. –see next
section.
Decide on the height required (always using the
lowest setting for the work in hand).

Be careful not to trap any fingers in this operation.
The use of a suitable platform ladder
may be required to reach the bolt-hole.
Insert the second bolt into the cheek-plate.
Tighten both bolts until spring washer is fully
