ABSTRACT
The invention provides lifting apparatus for
lifting, transporting and stacking shaped articles, e.g.
I-beams, both quickly and safely, and in such a manner that
the stacked articles occupy minimum space. The apparatus
has a cross beam rotatably supporting pairs of clamping
jaws which extend from the lower surface of the cross beam.
The pairs of clamping jaws are interconnected by alignment
means which ensures that the jaws are all kept parallel to
each other during rotation relative to the cross beam.
Groups of shaped articles can thus be clamped by the jaws
and lifted by the cross beam, so there is no need to stack
the articles with spacer members therebetween, which is
necessary when the articles are lifted by conventional cranes
or forklift trucks. Quick, safe and economical lifting,
transportation and storage can thus be achieved.
