This early 1940’s vintage Yale crane, a Model K31A-6, is the oldest electric Yale product in existence. As you can tell by one of the pictures, this type of electrical (Battery Powered) industrial truck was used for a myriad of factory tasks during World War Two. Some of the larger models were being used to hoist Pratt & Whitney engines onto aircraft.  This particular crane has always been in the New Haven & Fairfield area and is thought to have possibly been originally used at Chance Vought during the war.
