Coil unloading rig
摘要:
A coil unloading rig is adapted to handle, tilt and position a coil of sheet metal. An arcuate rail has opposed upper and lower open ends and an intermediate arcuate section. A trolley rotatably suspends the rail from a ceiling crane. A ring is disposed in a plane normal to the plane of the rail. A top brace is fixed to the upper rail end and the ring and a lower brace is fixed to the lower rail end and the ring. A pair of divergent posts are on each side of the lower brace, each post having post brackets for supporting and clamping the coil in a vertical position. A vertically movable brace bracket is movably mounted on the top brace for supporting and clamping the coil supported by the post brackets whereby the coil unloading rig is adapted to support and clamp a coil in a vertical position and tilt the coil by rotating the rail by the trolley to a horizontal position.
