Abstract
A stack of crane mats can be lifted by a sling which engages two or more lifting portions mounted to recessed walls. The lifting portions are configured such that a sling can lift a stack of mats. Each lifting portion includes an arm having a proximal end attached to a recessed wall of the mat and a distal end attached to a plate. A protrusion is mounted on each arm such that when the mats are stacked, the protrusions over lower mats are nested within recessed cutouts of upper mats. After a stack is landed, the sling may retain one or more upper crane mats and lift them away from a lower crane mat.
