To ensure the safe operation of your gantry, periodically inspect it for bent, broken, damaged, corroded,
c
racked or missing parts. The only regular maintenance that is required is to check bolt tightness and to
lubricate the casters through the grease fittings that are provided. Casters are prelubricated at the factory,
but when lubrication is needed use NLGI No.1 or No.2 grease.
The I-Beam is clamped in place at each end with four (4) beam clamps which firmly hold the beam in place. To
adjust the span, just loosen the bolts which hold the clamps and slide the beam to the desired span between
the legs. Do not move the legs (A-frames) inward more than one half (1/2) of the total I-Beam length. For
example, if the beam is 12 feet long, the distance between the A-Frames should never be less than six (6) feet.
After adjusting the span as desired, re-tighten all eight (8) bolts securely. Be sure you adjust both frames
inward when adjusting the span so one end of the beam does not hang over more than the other end. Do not
suspend a trolley or load from the cantilevered ends of the beam.
