A hybrid crane/rig mat that has outer side members of first and second side beams or boards of engineered lumber, oak or other hardwoods, or bumper members of solid or filled or unfilled hollow plastic members; a core structure of a metal or thermosetting plastic frame that includes side and end members and that contains therein a plurality of longitudinal members made of wood, engineered lumber, or of plastic or elastomeric materials; and a plurality of joining rods that pass through the outer side members, the core structure and longitudinal members to attach the outer side members to the core structure. The first end of the mat includes a male member and the second end of the mat includes a female member so that a first end of one mat can be releasably interlocked with a second end of a similarly configured and adjacently positioned additional mat.

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.

Various monolithic pavers are one-piece pavers with no seams, joints, or connections. A monolithic paver can be formed via three dimensional (3D) printing or molding. The monolithic paver is designed to carry applied loads to paver support(s) via structural members of the monolithic paver. The monolithic paver is formed to include parallel structural members that are spaced with gaps there between. The parallel structural members include top flanges and webs. The parallel structural members can also include bottom flanges. Moreover, the monolithic paver can have exterior sides that have tongues and grooves formed there along; tongues can be formed along adjoining exterior sides of the monolithic paver.

A bearing pad for receiving and retaining the substantially vertically oriented structural members of a module for use in constructing a pathway and supporting the pathway module on a ground surface can include a main body member having a lower ground engaging surface and a first slot defined by a first cross support member engaging portion of the main body member. The first slot can be planar and disposed transversely to the lower ground engaging surface of the main body member. The vertically oriented structural member that can be received and retained in the first slot by the first cross support member engaging portion of the main body member.

Moreover, the monolithic paver can have exterior sides that have tongues and grooves formed there along; tongues can be formed along adjoining exterior sides of the monolithic paver.

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.

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.

A paver locking system. The paver locking system may include; a paver assembly, including a paver; and straps attached to a back portion of the paver. The paver locking system may further include a paver spacer; and a securing mechanism for securing paver straps to the paver spacer.

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.
