SAFETY INSTRUCTIONS
Material handling is dangerous. Vestil strives to identify foreseeable hazards associated with the use of its
products. However, no manual can address every conceivable risk. The end-user ultimately is responsible for
exercising sound judgment at all times.
DO not install or use the crane in areas where it will contact electrified wires. Electrocution might occur
if the crane, hoist, or load, etc. contacts electrified wires.
Improper or careless operation might result in serious personal injuries.
• ALWAYS apply operation, inspection, and maintenance recommendations in 29 CFR 1910.179. Contact the
occupational safety and health institution of the state where the crane is used for requirements applied to jib cranes.
• DO NOT use a damaged/malfunctioning jib! Restore the crane to satisfactory condition before returning it to service.
• DO NOT exceed the capacity of your jib. See SPECIFICATIONS table on p. 2 or p. 3 . The weights of the load,
hoist, trolley, rigging, and all other equipment attached to the jib must be added together to determine the net weight
applied to the jib. The net weight must never exceed the capacity.
• Always perform the FUNCTION TESTS (p. 8) before each use.
• Inform all persons in the area to stay out of the area during operation.
• NO ONE should ever stand beneath or travel under the crane when a load is suspended from it.
• DO NOT use the jib to lift people.
• Do not hand from, or sit on, the boom.
• ALWAYS load the jib as recommended in USING THE CRANE on p. 8. Failure to properly position a load might
cause the load to swing when it is lifted. Load swing might result in serious injury.
• DO NOT use the crane if any label is unreadable, damaged, or missing. See LABELING DIAGRAM on p. 10.
Contact Vestil for replacement labels.
• DO NOT modify the crane! Modifications automatically void the LIMITED WARRANTY on p. 11 and might make the
crane unsafe to use.
ASSEMBLING THE CRANE
1) Insert the mast into the mast receiver. Install the
knobs and tighten them against the mast.
2) Pin the outer boom to the mast through the
pivot holes in the boom and the pivot pin holes in
the boom receiver. Secure the pin with a hitch pin.
3) Lift the end of the boom and insert another pin
through the selected holes (A-D) in the receiver.
Secure it with a hitch pin.
4) Slide the inner boom into the outer boom. The
inner boom has a series of pin holes along its length.
Review the diagrams and tables on page 2 or page 3
that match your boom model. Choose a length that is
appropriate for your application. Align the selected
holes in the inner boom with the pin holes in the end
of the outer boom. Insert the clevis pin and secure it
with a hitch pin.
