Abstract:
An industrial mat that has a support core configured and arranged to support other components of the mat; and upper and lower layers that provide upper and lower surfaces of the mat and that protect the support core. The support core includes a frame of longitudinal side members, end members and cross members each of which is made of steel or a thermosetting plastic material. The frame can include wood, plastic or elastomeric internal members or materials to fill internal open areas of the frame, with the upper and lower layers and the sides and ends of the frame retaining the internal members or materials therein. The mat preferably includes lifting elements of D-shaped rings, O-shaped rings, chains, or cables attached to the upper or lower layer or the support core to provide certified overhead lifting of the mat for installation and reclamation thereof.
Abstract:
A paving system for paving or flooring includes a top layer of a plurality of paving elements, and an underlayment support layer of a polymeric material configured into panels. The panels are suitable to support the paving elements, the panels having a generally planar support surface.
Abstract:
A crane mat having first and second side beams or boards; a core structure made of pine or other softwoods, eucalyptus, solid plastic or elastomeric members, or hollow thermoplastic, thermosetting plastic or elastomeric members that optionally include a filler or internal reinforcing structure; external components including an upper and/or lower layers of one or more elongated members to protect the core structure, and a plurality of joining members that attach the outer side members to the core structure. Another crane mat can be made of just the solid plastic or elastomeric members, or hollow thermoplastic, thermosetting plastic or elastomeric members that each include a plurality of spaced lateral apertures passing therethrough; and joining members that include a rod that passes through the aligned lateral apertures to hold the members together in the mat. These crane mats may also include lifting elements of the types described herein.
Abstract:
An industrial mat having a supporting structure; an upper layer provided above the supporting structure for forming an upper surface of the mat, a lower layer provided below the supporting structure for providing a lower surface of the mat; and lifting elements attached to the upper layer, the lower layer or the supporting structure. The lifting elements include D-shaped members, O-shaped members, U-shaped members, eyelets, hooks, circular or polygonal rings, chains, or cables that are configured and dimensioned for attachment to attached to the supporting structure or the upper or lower layer with sufficient strength to provide certified overhead lifting of the mat for installation and reclamation thereof.

Abstract:
A mat that includes first and second side beams, a core structure located between and connected to the side beams, with the support structure including longitudinal members and having a height that is less than that of the side beams, a plurality of joining rods that attach the side beams to the support structure, with the joining rods passing through the sides of the side beams and the sides of the longitudinal members of the support structure; one or more elongated members attached to the upper portion of the support structure to form with the beams the top surface of the mat, and one or more elongated members attached to the lower portion of the support structure to form with the beams the bottom surface of the mat. If desired, steel plates can be provided between the beams and longitudinal members to increase the strength and ruggedness of the mat.
Abstract:
A vehicle energy harvesting roadway is provided. The vehicle energy harvesting roadway includes a deformable driving surface that is longitudinally flexible and transversely stiff. The deformable driving surface is disposed between a passing vehicle and one or more transducers or one or more compressible hoses.

Abstract:
A paving system for paving or flooring includes a top layer of a plurality of paving elements, and an underlayment support layer of a polymeric material configured into panels. The panels are suitable to support the paving elements, the panels having a generally planar support surface and a recovery characteristic such that a deformation from a concentrated compressive load applied for a short duration returns the support surface to a generally planar condition.
Abstract:
A system including a pavement module that includes a protective system against wear and tear of rigid support elements of interconnected modules that form a covering of a pavement, or impact absorbers that integrate or are coupled to the pavement modules. The system consists of a pavement module with an upper side and a wear-protective system consisting of a protective shoe.
