• Save for future reference.
SEVERE INJURY OR DEATH HAZARD!
• This Gantry Crane is designed for lifting heavy objects only.
• DO NOT move Gantry Crane while loaded.
• DO NOT concentrate a heavy load to either side of the Gantry Crane. This can cause the balance to shift suddenly,
tipping the Gantry Crane which can quickly cause severe injury!
• DO NOT exceed the rated 2000 lbs. [908kg.] weight capacity.
• DO NOT use to support humans or animals.
• DO NOT climb on the Gantry Crane.
• DO NOT use the top of the Gantry Crane to support items other than an approved lifting device.
• DO NOT attempt to use with powered lifting devices.
• DO NOT use with lifting devices and/or chains, cables or ropes that are frayed, twisted, kinked or otherwise damaged.
• DO NOT remove or cover any of the factory supplied labels or warnings! They include specific safety information that must
be communicated to future users.
FALL HAZARD!
• Awkward, out of balance body positions may be attempted while trying to reach specific areas of objects placed on the Gantry Crane
during use. Failure to ensure proper footing can quickly result in a fall which could inflict serious personal injury or property damage.
PINCH/CRUSH HAZARD!
• This Gantry Crane has moveable components that can crush and pinch. Keep fingers and hands away from pinch points
when operating.

ASSEMBLY PREPARATION
• Obtaining the assistance of a helper during assembly is necessary. DO NOT attempt to construct this Gantry Crane without assistance!
• The use of ANSI approved safety shoes, head protection gear and eye protection is necessary.
• Use saw horses or similar work stands (not included) to support larger components such as Posts and I-Beams during assembly.
• Perform assembly in a large, uncluttered area close to area of intended usage.
• Consider vertical clearance when choosing operation area.
• Allow sufficient area for operator and helper to remain clear when choosing operating area.
• Use only on a smooth, level and clean work surface. DO NOT use on a sloped or rough textured surface, earth, grass, sand, gravel or any other loose
or unfirm surface.
• DO NOT attempt to move the Gantry Crane while it is supporting a load.
• DO NOT attempt to raise or lower the “I”-Beam while it is supporting a load.
INJURY HAZARDS!
The Eastwood Gantry Crane consists of considerably heavy metal components (550 lbs. [250kg.] assembled weight) which can
cause potentially serious injuries if allowed to drop. Avoid pinching hands while handling parts during assembly.
The Posts are pre-assembled with Pullies, Cables, Winches and Guide Tubes before shipment.
To prevent scratches and damage to the finish of the Gantry Crane components, it is strongly advisable to use cardboard, carpet,
blankets etc. covering a minimum 10’ x 10” area before beginning assembly.

BASE/CASTER ASSEMBLIES TO POST/”I-“BEAM ASSEMBLY
• With your helper lifting the opposite side, carefully raise the
flanged ends of the Gantry Crane Post & Beam assembly so
that it may be set up off the floor on sawhorses, work stands
or similar supports (FIG 6).
• Attach the Left and Right Base/Caster assemblies by inserting
the Guide Tubes of the Posts into the Sleeves of the Base/Caster
assemblies, aligning the holes using Eight M12 x 110mm bolts,
M12 Washers, M12 Lock Washers and M12 Nuts (FIG 7).
• Check for squareness of the assembly then tighten all
hardware securely.
• With the assistance of a helper, carefully rotate the entire

OPERATION
SETTING “I”-BEAM HEIGHT
• Lock the two Locking Swivel Casters by pressing down on the
Brake Lever. This will prevent the Gantry Crane from moving.
To release brake feature, lift-up on Brake Lever.
• Remove Pin Retaining Clips [H] from Height Pins [J] then
carefully remove Height Pins [J] (FIG 10).
• Rotate the Handcranks [G] to operate the Winch Boxes and raise
or lower “I”-Beam.
• Rotate Clockwise to raise “I”-Beam.
• Rotate Counter-Clockwise to lower “I”-Beam.
• Once the desired “I”-Beam height has been achieved, reinstall
Height Pins [J] and secure in place with the Pin Retaining Clips
[H] (FIG 10).
Due to the size and considerable weight of the
Gantry Crane components it is necessary to
obtain the assistance of a capable helper during
the following steps.
OPERATE BOTH POST WINCHES AT THE SAME
TIME to keep the Inner Posts from Binding within
the Outer Posts.
Store the Gantry Crane on a flat, level surface
only to prevent possible unattended rolling
and property damage.
When selecting attachments and lifting devices
for use on the Gantry Crane, make sure that they
are compatible with the “I”-Beam dimensions
(3” W x 5” H [76.2 x 127mm]) and are safely
capable of supporting the 2000 lb. [908kg.]
weight limit of the Gantry Crane.
