Bulk bag support for filling

A bulk bag support for filling, said bag having at least a bottom wall extending upwardly from a perimeter of the bottom wall and a sidewall terminating in a top perimeter and plural handles spaced around the top perimeter, comprising:

• a frame, said frame including a ground engaging base adapted to engage the bottom wall and support the bulk bag during and after a filling thereof and an upstanding column;
• a mounting platform on said frame and overlying said base;
• a plurality of spaced support means on said mounting platform, each of said support means including selectively actuable means supported for movement between first and second positions for respectively selectively gripping and releasing said handles, said selectively actuable means, when in the first position, non-releasably gripping said handles thereby causing said bulk bag to be suspended from said support means and above said base for filling and, when in the second position, releasing said handles thereby causing said bulk bag to rest on said base, wherein said selectively actuable means includes a bracket mounted on said mounting platform and a hook member pivotally mounted on said bracket and adapted to grippingly engage and release said handles, said hook member including an arcuately shaped, upwardly facing handle engaging surface having a distal end juxtaposed said bracket when said selectively actuable means is in the first position to thereby prevent the handle passing therebetween, a center of said arcuate handle engaging surface approximating a pivot axis for said hook member so that when a weight force from said bulk bag is applied to the handles, a theoretical vector of the force will be transmitted through said bracket adjacent said pivot axis;
• and
• yieldable biassing means for continually urging said selectively actuable means toward said first position.
