Tri-Adjustable Aluminum 1/2 To 3 Ton Gantry Cranes

Tri-Adjustable Aluminum 1/2 To 3 Ton Gantry Cranes | Wallace Cranes

The lightweight aluminum Wallace tri-adjustable 1/2 to 3-ton crane is our most popular product line. Current applications include use in chemical, optical, and electronic clean rooms. In addition, many customers use our cranes for HVAC, electrical utilities, WWTP, municipal maintenance (including subways, buses, and building facilities), hospitals, universities, airports, and the military.

With adjustable height, span, and tread, Wallace Cranes provide flexible lifting solutions. The aluminum design makes these cranes the ideal combination of high lifting and reduced weight. They are easily assembled and disassembled for convenient portability.

Available accessories include manual or powered trolleys and hoists, jack kits for frequent crane height adjustments, and kart kits for transporting and/or storing cranes. Options for track mounting with V-groove casters and motorizing cranes are also available.

  • 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 truck 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 aluminum tubing is 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 leg spacing adjustments and cantilever configurations
    • Height Adjusting Bolts – Main legs are equipped with spring-loaded bolts permitting crane height adjustment – 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 at 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
  • Designed to roll under load
