Durable, Stable, Adjustable, and Portable
Our most popular product line is the lightweight aluminum tri-adjustable 1/2 to 3-ton gantry crane. The aluminum design makes these cranes an ideal combination of high lifting and reduced weight. Made with high-quality heavy-gauge aluminum tubing, our 1/2 to 3-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.
Available accessories include manual and electric trolleys and hoists, jack kits for frequent crane height adjustments, kart kits for transforming your disassembled crane into a cart which allows for easy transport and storage, and festooning kits to keep hoist, trolley, and power drive system cords up and out of the way.
Options for track mounting with V-groove casters and motorizing cranes are also available.
