NATIONAL STANDARDS
This product is a fixed jib crane. ASME standard B30.17 (the “Standard”) applies to jib crane’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 jib crane 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. Purely cosmetic changes, like damaged paint/powdercoat, are not changes from
satisfactory condition. However, touchup paint must be applied as soon as damage occurs to prevent rust from
forming. Rusting could cause the affected part to become unsound, which could also make the crane unsafe to
use.
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) I-Beam fasteners – Fastened connections are shown in Step 4 on p. 7. Verify that all lock washers are
fully compressed. If you must remove a lock nut, replace it with an unused nut.
3) Beam brackets (see Step 4 , p. 7) – Look for damage, e.g. cracks, warps, bends, elongations, or
significant rusting/corrosion, around bolt holes. Inspect the bracket plates for damage.
4) Pins – Check all 4 clevis pins and corresponding cotter pins. Pinned connections are shown in Steps 3
& 4 on p. 7. All 4 of the clevis pins should be fully inserted and secured in place with cotter pins.
5) Yokes– Closely examine all 4 yokes. Look for cracks, bends, chips, warps, and other forms of
damage. Pay particular attention to the pin holes. Make sure that there are no elongations, warps, or
cracks around the openings. Jam nuts should be tightly wound against the corresponding yokes.
6) Base frame – Look for damage such as cracks, bends, warps. Pay particular attention to anchor bolt
holes & bolt holes in mounting brackets. Look for rust, metal rot, corrosion where the metal frame
contacts the floor.
B. Monthly inspections – Unload the crane and inspect the following:
1) Beam bracket and fasteners – Use a torque wrench to tighten each bolt and nut to 50- 52ft∙lb.
Examine all of the brackets for damage such as deformations and cracks. If you must remove a lock
nut, replace it with an unused nut.
2) Clevis pins : Closely examine each clevis pin and its cotter pin for damage. Clevises should not be
bent or cracked or significantly worn.
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 D 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.
