Key Features
Durable, Stable, Adjustable, and Portable
One of our most popular product lines is the steel tri-adjustable 3 and 5-ton gantry crane. The steel design makes these cranes incredibly strong and durable. Made with high-quality heavy-gauge steel tubing, our 3 and 5-ton Tri-Adjustable gantry cranes are designed to roll under load. They have an adjustable height (C), span (B), and caster frame spread (E).
- The Tri-Adjustable is built using our patented pinned-joint design resulting in a longer-lasting, better-fitting, more flexible crane that is quick and easy to assemble and disassemble.
- Exclusive Wallace I-beam support system aligns off-center loads to avoid crane and trolley distortion. Support system slides along the I-beam enabling leg spacing adjustments and cantilever configurations.
- Casters are equipped with a 4-position swivel lock. When locked 90 degrees with each other, they position the crane more firmly than a brake.
- Adjustable legs permit crane height adjustments in 6″ increments using spring-loaded bolts. You can raise the height of your crane so it goes over materials and equipment, lower it under low ceilings and doorways, or set legs at different heights when floors or terrains are uneven. It’s ideal for truck loading or from a dock to a floor or ground level to a mezzanine.
- Adjustable span allows for inboard or outboard bracing and a cantilever configuration overhang of up to 25% of the I-beam length.
- Adjustable caster frame spread (E) enables rolling through narrow aisles or doorways and prevents having to disassemble and reassemble your crane. Safety cables inside the caster frame tubes prevent overspreading while adjustments are underway. Casters are equipped with 4-position swivel locks to position the crane more firmly than a brake.
- Tri-Adjustables can be wheeled around to serve more than one workstation or workplace. Lock “lead” casters and unlock trailing casters to easily move and steer crane. An optional Kart Kit transforms your disassembled gantry crane into a cart, allowing easy transportation and storage.

Assembly and Disassembly Instructions
Cautions
- Read and understand instructions before using this gantry.
- Inspect gantry thoroughly before using. See the Tri-Adjustable Operating, Adjustment, and Inspection Instructions (Form 379) for damaged or missing parts.
- Do not lift more than rated capacity.
- Center hoist over the load.
- Do not allow the load to swing or roll against any supporting members.
- When moving the gantry under load, push on the gantry, not the load. Be certain that the rolling surface is hard, level, clean, and smooth.
- Do not move the gantry over 50 feet per minute (1/2 m.p.h.).
- Not to be used for lifting or supporting humans.
Before You Begin
- Place parts on a flat surface, preferably on cardboard to keep small parts clean and organized.
- Select a clear area to assemble the crane. The work envelope should extend five feet beyond twice the leg length (when flat) and the length of the I-beam.
- This clear area should be serviced by two overhead hoists or an alternate as shown below as well as in Form 379. This will allow you to raise the I-beam and leg assemblies when required.
- Select tools for fastening the nuts and bolts.
- You will also need C-clamps to hold the trolley in place while the crane is assembled.

Engineering Specification
Gantry end frames shall be of steel square-tube construction manufactured to Wallace Cranes standards, including, but not limited to the following:
- Gantry shall be adjustable in height and have main leg ductile iron center castings for brace leg attachment to main support legs.
- Gantry shall be adjustable in span so that operators may adjust the crane to an inboard braced, outboard braced, or a combination of the two or approved cantilevered configuration.
- Gantry shall be adjustable in caster frame spread and have ductile iron castings for attachment of casters.
- The steel I-beam shall be American Standard and have a design deflection of no greater than l/800th of the span. The I-beam shall also be free-swinging and self-aligning to lift off-center loads as approved.
- The telescoping legs shall be adjustable in 6” increments and also be equipped with malleable iron safety stops for everyday use as well as when adjusting height.
- Spread adjustment on the caster frame shall be in 6” increments. Over spreading of the caster frame adjustment shall be prevented by means of an internal steel safety cable.
- The main leg ductile iron center castings shall have spring-loaded pearlitic grade load-adjusting pins for adjusting/maintaining height adjustment of crane as well as attachment of brace legs.
- Gantry shall be equipped with eight, 360 degree rotating, non-marking phenolic resin casters with 4-position swivel locks, at 90 degrees, to provide easy steering of crane by locking “lead” casters only, or to allow positioning of crane more firmly than a brake by locking all eight casters 90 degrees to each other. Casters shall be 8” diameter.
- The I-beam and I-beam brackets shall be painted with red gloss industrial quality paint.
- The frames, including brace legs, caster frames, and main legs shall be dip painted with red gloss industrial quality paint for protection of both inner and outer tubing walls.
- The model number to be provided shall be tested in accordance with B.E. Wallace Products Corp. specifications (A specific unit shipped is not tested; unless a Certificate of Test is ordered [additional charge applies]).
- Gantry is manufactured in accordance with our interpretation of ANSI B30.17 and U.S. OSHA, (Section 1910.179, revised January 1976), regulations at the time of manufacture.
