Gantry Crane is our most versatile unit. You can adjust Height, Span, and Width.
Identical units have been used for applications as diverse as
waste-water treatment, particle physics, and helicopter maintenance.
These cranes can also be used in a cantilever configuration, making
sure the proper counterweights have been applied. These cranes can be
made narrow and short to fit through doorways. With the pinned
construction, they can even be quickly disassembled and moved on an Accessory
cart within a worksite.
Adjustable Span and
span gives more advantages - bracing may be inboard or outboard or
cantilever configuration. Cantilever overhang is limited to 25% of the
I-beam length. Cantilever capacity is limited to 60% of the rated load.
(NOTE: A counterweight may be required, consult factory before using
crane in a cantilever configuration.) No matter which configuration you
use, our push trolleys with hand or electric hoists will travel the
entire length of the I-beam.
main legs permit crane height adjustment at 6 inch intervals. Frequent
height adjustment is speedy with optional Crane Jack Kit.
Height can be raised to go over equipment or material in its
path; lowered to go under low ceilings, obstructions or through doors.
Legs can be set at different heights where flooring or terrain is
uneven. It's ideal for loading from truck dock to floor or from ground
level to mezzanine.

Only high quality, heavy gauge steel and aluminum tubing are used.
I-beams are American standard. Every steel gantry is dip painted with
red gloss industrial quality paint to protect both inner and outer
tubing walls. All bolts, pins and hardware are plated to prevent
Tri-Adjustable Gantries are offered in all aluminum alloy
construction for lightweight and maximum portability. Combination
models have aluminum alloy I-beams with steel A-frames for light weight
and lower cost. All steel construction gives you the greatest capacity
at lowest cost.
Self Aligning I-Beam
exclusive Wallace I-Beam support system will align with off-center
loads to avoid crane and trolley distortion. Best of all, the Wallace
support system slides enabling you to adjust leg spacing, and set up
for cantilever configurations. More details are found here.
Height Adjusting Bolts
legs on all models are equipped with spring loaded bolts permitting
gantry height adjustment at 6 inch intervals. They can be locked out
until the desired height is reached, then unlocked to engage
position swivel lock casters offer special advantages. Locked at
90° to each other, they position the crane more firmly than a
Lock "lead" casters and unlock trailing casters to easily
move and steer the crane. Standard on all cranes (except for the 15
ton, which is equipped with four 10" diameter steel V-grooved wheels),
are durable composition wheels. Ideal for all floors, they are
non-marking and non-sparking. All round tube gantries are equipped with
four 6" (or 8" depending on load capacity) diameter wheels and the
square tube Tri-Adjustables have eight 8" or 10" diameter dual wheels.
Alternate steel V-grooved casters are available for all cranes for use
on angle iron track.
Completely Portable Tri-Adjustable
steel pins with locking rings provide quick assembly and disassembly.
Some aluminum cranes may be hand carried. Or, get the optional "Kart
Kit" which transforms our disassembled crane into a hand cart, for easy
storage and transportation.
