With adjustable height, span, and tread, our all-steel tri-adjustable cranes provide flexible lifting solutions. 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.

Tri-Adjustable Square Tube Assembly and Inspection Instructions

• I-beam spans from 10′ – 35′
• Completely adjustable
• 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 in 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 steel 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 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
  • The optional “Kart Kit” is available and transforms your dissembled crane into a cart which allows easy transportation and storage
• Designed to roll under load
