Abstract
A quick connect/disconnect tank lifting brace which lifts a tank from an overhang of it's top lid or cover. The brace includes a crossbar, preferably adjustable, with pivotal end clamps at opposite ends of the crossbar. A pair of clamp pivoting assemblies are provided. Each clamp pivoting assembly pivots a respective one of the pivotal end clamps between an open position and a closed position and biases the pivotal end clamp to an open position for quick connection and disconnection. Pivoting is accomplished using an actuating rod parallel to the crossbar and coupled to the pair of pivoting assemblies. Articulation of the actuating rod effectuates, in unison, pivoting of each pair of pivot arms via the pivoting assemblies to a closed position. The pivoting assemblies generally utilize a push to close and pull to open motions.
