发明名称 Structural composite glulam-steel rig mat
摘要 A Structural Composite Glulam-Steel Rig Mat includes a unique steel frame. The unique steel frame includes unique lifting eyes for cranes in the corners of the rig mat and smooth radius steel channel around the perimeter of the rig mat to enable easy handling by forklifts. The unique steel frame surrounds unique full length, engineered glulam beams which together with the steel frame make the resulting rig mat significantly stronger than the traditional rig mat.
