  • I-beam spans from 10′ – 35′
  • 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 adjustments 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 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

    • Lock “lead” casters and unlock trailing casters to easily move and steer crane
