Installation
Determine the extra height required, and select riser
blocks of appropriate height. One end of the gantry
has long threaded rods topped by washers and nuts.
Loosen the nuts on the threaded rods. On the other
end of the gantry, loosen the bolts. Raise the gantry
for clearance, and slide a riser in between the two
tower blocks on each end of the gantry. For higher
extensions use the longer bolts and additional riser
extensions as needed. Always add the same height
to each end of the gantry. When finished installing
the riser blocks, be sure to tighten all bolts and
threaded rods.
