发明名称 Method for handling concrete retaining wall blocks
摘要 A method and apparatus for handling large concrete retaining wall blocks and the like. The blocks are cast in a form with the front face down, a lifting loop extending from a rear face and with grooves extending in sides from a rear face to adjacent the front face. A spear hook is secured to one of two fork lift tines to extend to one side of the tine away from the other tine. The spear hook engages the lifting loop on the block for lifting the block from the form and for rolling the block into an upright position. The fork lift tines then engage the side grooves from the rear of the block for lifting and moving the blocks and for stacking the blocks to construct a retaining wall.
