Wallace steel frame, aluminum I-beam, 3 & 5-ton adjustable height gantry cranes are ideal for maintenance, manufacturing, repairs and other material handling tasks.
Many customers use our cranes for HVAC, assembly, and repairs of physical equipment. Some of our current users include electrical utilities, municipal maintenance (including subways, buses, and building facilities), hospitals, universities, research institutions and the military.
With adjustable height, span and tread, Wallace tri-adjustable portable gantry cranes provide flexible lifting solutions. The steel frame and aluminum I-beam design make these cranes the ideal combination of high lifting capacity and reduced weight. We also offer all-steel tri-adjustable 3 and 5-ton gantry cranes.

I-beam spans from 10′ – 15′ (up to 20′ spans on 1-ton models only)
Adjustable span allows inboard or outboard bracing
Adjustable span allows cantilever configuration overhang limited to 25% of the I-beam length
Adjustable legs permit crane height adjustment at 6″ increments
Raise height to go over equipment, material, etc…
Lower height to go under low ceilings, doorways, etc…
Legs can be set at different heights where floor or terrain is uneven-ideal for loading from dock to floor or from ground level to mezzanine
Adjustable caster tread to roll thru narrow aisles or doorways which prevents costly disassembly
Safety cable attached inside of caster frame tubes prevents overspreading when adjusting
Durable construction – high-quality heavy gauge steel and aluminum tubing are used
Self-aligning I-beam – Exclusive Wallace I-beam support system aligns off-center loads to avoid crane and trolley distortion
I-beam support system slides along the I-beam enabling fixed leg spacing adjustments and cantilever configurations
Height Adjusting Bolts – Main legs are equipped with spring-loaded bolts permitting crane height adjustments – they can be locked out until the desired height is reached, then unlocked to engage automatically
Casters equipped with 4 position swivel lock – when locked 90 degrees with each other, they position crane more firmly than a brake
Lock “lead” casters and unlock trailing casters to easily move and steer crane
Alternate steel V-grooved casters are available for use on angle iron track
Completely portable – Stress-proof steel pins with locking rings provide quick assembly and disassembly
Many aluminum crane models can be hand-carried
The optional “Kart Kit” is available and transforms your disassembled crane to a cart which allows easy transportation and storage
