The gantry is now erect at its lowest height setting.
Release trolley brake and castor brakes to position
the gantry over the load ensuring, when possible,
that the load is lifted from the center of the beam
Beam height adjustment bolts (2 bolts on each upright).

Assembly Instructions
Insert and tighten the final beam bolt
Decide on the height required (always using the
lowest possible setting for the work in hand).
Adjust the upright position
If the hoist is not already attached to the
suspension point on the trolley, do so now (using
stepladder if height setting requires)
If this is not safe, disassemble the gantry and
re-start adding the hoist prior to scissoring the
A-Frames
Ensure the beam is horizontal and
castors are locked prior to any lift.
