Abstract
The lifting apparatus is a mechanical structure. The lifting apparatus is configured for use in manually lifting a load. The lifting apparatus attaches to the load such that a plurality of individuals are able to simultaneously lift the load. The lifting apparatus comprises a master beam, a grasping structure, and a rigging chain. The grasping structure and the rigging chain attach to the master beam. The plurality of individuals manipulate the lifting apparatus using the master beam. The grasping structure attaches the load to the master beam. The grasping structure adjusts to accommodate the form factor of the load. The rigging chain is a secondary attachment structure that attaches the load to the master beam such that the loading distribution of the load is balanced relative to the master beam such that the lifting apparatus is more easily manipulated by the plurality of individuals.
