the crane in satisfactory condition. Compare the results of all INSPECTIONS to this Record to determine whether
the crane is in satisfactory condition. Do not use the crane unless it is in satisfactory condition. Purely cosmetic
changes, like damaged paint or powdercoat, are not changes from satisfactory condition. However, touchup
paint should be applied as soon as damage occurs. If your crane is not painted or powdercoated, touchup
paint is not required.
NATIONAL STANDARDS
This product is a portable A-frame gantry crane (PGC). ASME standard B30.17 (the “Standard”) applies to
PGC’s. You should acquire a copy of the latest version of the standard. Follow all use and maintenance/care
instructions provided in the Standard as well as all other provisions for PGC owners and users. If any content in this

from the Standard. Vestil encourages you to immediately contact Technical Service if you discover any
inconsistencies.
INSPECTIONS AND MAINTENANCE
NOTE: Inspection procedures are included in the most current revision of ASME B30.17. As stated above in the
NATIONAL STANDARDS section, Vestil recommends that you acquire a copy of the most recent revision of this
standard. Apply all use and maintenance/care instructions in the standard. Vestil also recommends that you
contact your local occupational health and safety authority to determine if any laws, regulations, codes,
ordinances, etc. apply inspection requirements where the crane is used.
Inspections and all necessary repairs should be performed by qualified persons. Compare the results of each
inspection to the RECORD OF SATISFACTORY CONDITION. Do not use the crane unless every part is in satisfactory
condition. DON’T GUESS! If you have any questions about the condition of your crane, contact the Technical
Service department. The phone number is provided on the cover page of this manual. Never make temporary
repairs of damaged or missing parts. Only use manufacturer-approved replacement parts to restore the crane to
satisfactory condition.
A. Before and after each use, including first use, unload the crane and inspect the following components:
1) I-Beam – Examine the beam, especially the lower flanges, for bends, cracks, and other damage.
2) Beam clamps and beam clamp fasteners – Clamp connections are shown in Step 4 on p. 19. Verify that all
lock washers are fully compressed. The clamps should equally overlap the I-beam flange.
3) Beam brackets – Look for cracks, elongations around bolt holes, warps, bends, etc.
4) Casters and caster fasteners – Examine each caster for cracks, warps, tears, grooves, pitting, and
significant wear. Push the crane a short distance. All 4 casters should be in continuous contact with the
ground. Confirm that the casters roll smoothly without wobbling or skidding. Make sure that caster
fasteners are tightly connected. Fastener connections are shown in Step 8 on p. 20.
5) Pins – Check both adjustment pins (all models) and all 4 clevis pins (AHA-2 and AHA-4 models only). Pinned
connections are shown in Step 2 on p. 18. Both adjustment pins should be fully inserted and pin stops
should be perpendicular to the pins to secure them in place. All 4 of the clevis pins should be fully inserted
and secured in place with cotter pins.
6) Yokes (AHA-2 & AHA-4 models) – Closely examine both yokes. Look for cracks, bends, chips, warps, and
other forms of damage. Pay particular attention to the openings in the yoke. Make sure that there are no
elongations, warps, or cracks around the openings.
7) Leg tubes (AHA-2 & AHA-4 models) – Check all 4 of the leg tubes for damage.
8) Leg assemblies (AHA-6 & AHA-8 models) – Inspect both leg assemblies. Look for cracks, bends, warps, and
other forms of damage. Pay particular attention to pin holes & bolt holes. Look for elongations, cracks, etc.
B. Monthly inspections – Unload the crane and inspect the following:
1) Beam clamps and beam clamp fasteners – Use a torque wrench to tighten each bolt and nut to 50-52ft∙lb.
Examine all of the clamps for damage such as deformations and cracks. The I-beam flange should be
solidly/immovably clamped to the tops of the uprights.
2) Lay the crane over so that the I-beam is on the ground and inspect:
a) Pins
i. Adjustment pins (all models): One at a time, remove each adjustment pin and examine it. Look for
cracks, warps, pitting, and other forms of damage. Confirm that the pin stop operates normally.
Reinsert each pin after inspecting it.
ii. Clevis pins (AHA-2 & AHA-4 models): One at a time, inspect each clevis pin. Closely examine the
clevis pin and its cotter pin for damage. Remove the leg tube and perform the indicated
inspection. When the inspection is finished, reinstall the clevis pin and its cotter pin.
b) Leg tubes – Examine the pin holes in the top end of each leg. Look for elongations, cracks, and other
forms of damage. Reinstall each leg once its inspection is finished.
C. Once per year: Perform a load test of the crane. Lift a load equal to 125% of its rated load (capacity). Only
lift the load high enough to ensure that it is entirely supported by the crane. Transport the load by means of your
