Abstract
A bale handling device, more particularly a bale pick-up device, includes a plurality of squared C-shaped hooks which are individually pivotally mounted between pairs of elongate support members and pivotally mounted to actuating members for pivoting into a raised position out of engagement with the bales and a lowered position into engagement with the bales. Forces are applied via the actuating members to raise and lower the hooks by a pair of operating members which connect the actuating members to the piston end and the free end of a hydraulic cylinder. The cylinder is not fixed, but is free to float, effecting force equalization and preventing damage to the mechanism if an obstruction is encountered.
