General Engineering Product 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 each main support leg shall include a brace leg.
  • 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 have a fixed caster frame spread with welded caster frame plates 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 telescoping legs shall be adjustable in 6” increments and also be equipped with ½” diameter steel round bar safety stops for everyday use as well as when adjusting height.
  • The main legs shall have ½” diameter steel round bar load-adjusting pins for adjusting/maintaining height adjustment of crane as well as attachment of brace legs.
  • Gantry shall be equipped with four, 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 the crane more firmly than a brake by locking all four casters 90 degrees to each other. Casters shall be 6” in 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 to protect the inner and outer tube walls.
  • The model number to be provided shall be tested in accordance with Wallace 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.
