摘要： A crane mat system includes a top surface and a bottom surface constructed of steel plates. The top surface and the bottom surface are joined by one or more sides and an internal support structure. Two or more lifting portions are mounted to recessed walls. 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. Each arm is mounted above the midline of the height of the mat. 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. The lifting portions are configured such that a sling can lift a stack of mats.

摘要： 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.
