Abstract
An X-Y bridge crane can be assembled and erected by workmen to lift and move loads at the end of a shipping and stowage container having block-shaped corner fittings at top corners and bottom corners. Rotatable top securing brackets engage the top block-shaped corner fittings and rotatable bottom securing brackets engage the bottom block-shaped corner fittings. Inner end portions of brace members are rotatably connected to the rotatable bottom securing brackets. A framework having inner extensions, outer projecting parts and a laterally extending hoist-traveling beam has inner extensions connected to the top securing brackets and outer projecting parts connected to the outer end portions of the brace members. A hoist is mounted on the hoist-traveling beam to lift and move loads on the framework, and first and second chainfalls connected to the hoist linearly displace the hoist in orthogonal directions.
