Assembly Instructions - Vestil AHS Manuel D'utilisation

Review this entire page before assembling the crane.
Consult the factory in the event there are any questions or problems at the time of assembly.
• The model FHS fixed-height steel gantry crane and the AHS and AHA adjustable-height steel and aluminum gantry
cranes are suitable for use indoors and outdoors for many industrial and commercial applications.
• Modifications or additions to the gantry crane without prior authorization from the manufacturer may void the
crane's warranty.
• Assembly must be performed by suitably trained personnel with the appropriate tools and equipment.
For assembly you will need the following:
1. A fork truck or overhead hoist or crane.
2. Basic fastener tightening hand tools such as a wrench set or a socket set,
an adjustable wrench, etc.
Installing the crane's top beam and leg assemblies together:
1. On adjustable-height models, (AHS and AHA), insert the upper frame sides
into the lower frame sides and secure both sides at the same level with the
height adjustment pins and clips.
2. Lay out the crane's top beam and the two leg assemblies on a floor area
that has ample clear working space.
3. Loosely attach the beam spur clamps and shims (shims are used on steel
units only - 1/8" thick for 5"-8" I-beams, 3/16" thick for 10"-12" I-beams, but
none are used on 4" wide I-beams) to the top flanges on both leg assemblies
using the 1/2" -13 structural bolts and nuts provided, as shown in the
illustration.
4. Slide the bottom flange of each end of the I-beam between the spur clamp
shims and the leg assemblies' top flange until the desired usable beam length
is attained.
5. Tighten all the spur clamp nuts to a torque of 50-52 foot-pounds.
6. Tip the gantry assembly upright using a fork truck or overhead crane.
7. Lifting at the center of the cross beam, slowly raise the assembled gantry
just high enough to install the casters.
Installing the casters to each leg:
8. Hold an 8" caster under the bottom flange of each leg of the crane so that
the caster rig's holes match the holes in the leg's bottom flange.
9. Hang a caster from the bottom of each leg, installing one bolt and flat washer
(from the bottom) in each caster rig at a corner nearer the center of the leg set.
The 2,000 lb - 4,000 lb capacity gantries have 5/16" -18 UNC threaded holes, the
6,000 lb. capacity has 1/2" -13 UNC threads, and the 8,000 lb has drilled holes
for 1/2" bolts in the legs' bottom flanges. Only the 8,000 lb. capacity steel gantry
uses nuts to mount the casters.
10. Insert the detent assembly under the caster rig, as shown, and install the
remaining three fasteners.
11. Tighten the bolts to standard US bolt (SAE Grade 2, zinc-plated)
specifications - 5/16" bolts = 9 lb.-ft., 3/8" bolts = 16 lb.-ft., and 1/2" bolts =
38 lb.-ft.
12. Rotate the wheels so that all are parallel with each other, then lock them in
place with the detents.
13. Slowly lower the completed gantry crane so that it rests on the casters.
14. Once fully assembled, and before the first use, the gantry must be tested at
its full rated capacity per standard ANSI/ASME B30.2.
