Bolt 2
Bolt 1
The gantry beam has adjustment holes to narrow the
footprint of the gantry. This is best done when the gantry
is assembled with 2 persons sliding the A-frame inwards
while 1-2 persons steady the gantry by holding the beam
– this will require the use of a step ladder. If this process
is required to be carried out often then an upgrade to
‘lobed cheek plates’ can be purchased which allows
the gantry to be assembled as steps 8-21 but with one
A-frame inward from the end of the beam.

PORTA
GANTRY
500-3000
Offer opposite side of beam to the rear bolt-hole
on the cheek-plate (bolt 1) and insert bolt
Put on plain washer, spring washer then nut,
finger tight
With the help of another person, scissor the beam
and A-Frame into position (using the first bolt as
a hinge). Be careful not to trap any fingers in this
operation
Insert the second bolt into the cheek-plate.
Tighten both bolts until spring washer is fully
depressed, be cautious not to overtighten
At this stage it is useful to attach the lifting device
to the trolley in order to avoid having to lift and
attach when gantry is fully erect.
This avoids a working at height problem when
attaching a hoist
Keep hands clear of potential “Pinch” area marked with
warning tape, in the scissoring system. The chain hoist
must be positioned at the opposite end of beam.
Move trolley to other end of beam, opposite to
the end to be raised, and secure by tightening
the trolley knob
Repeat the scissor activity at the opposite end of
the gantry
For additional safety, a spare bolt can be
temporarily placed in the adjustment point.
This illustration demonstrates the bolt positions
(1 & 2) for the cheek plates.
Lay the two A-Frames a beam length apart on a
flat surface in line with each other with the castor
wheels outward and brakes on
Lay the beam on the A-Frames, resting on bolt 1
on each cheek plate
Thread the beam trolley over the other end
of the beam and lock with the friction brake at
approximately centre position. If using a gated
trolley, lock with the friction break
Offer one end of the beam to the rear bolt-hole
on the cheek-plate (bolt 1) and insert a bolt
Put on plain washer, spring washer then nut,
finger tight
