powdercoat, are not changes from satisfactory condition. However, touchup paint should be applied as soon as
damage occurs. If your crane is comprised of unfinished metal parts, 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 manual
conflicts with any recommendations or mandatory provision(s) in the Standard, apply the provision(s) 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 entire 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. Visually
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 and 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
hoist (or hoist & trolley) the full usable length of the I-beam (dimension C in SPECIFICATIONS table). Return the
test load to the ground. Perform inspections A (Before and after each use) and B (Monthly).
NOTE: Perform this part C (Load test and a Before & after use inspection) whenever the crane is partially or
fully disassembled and reassembled, e.g. after installing replacement parts.
