A structural reinforced composite construction mat includes a plurality of composite plastic beams that are ganged together to define the mat, with a plurality of flitch plates disposed between at least some of the plastic beams to provide additional strength and rigidity to the mat. The plastic beams may be made of a composite material have a generally rectangular cross-section. The flitch plates have a width (vertical height) when disposed between adjacent beams that is less than the width (vertical height) of the beams, such that the flitch plates may be recessed below and above the top and bottom surfaces of the mat, respectively. A plurality of rods extend in the lateral direction through the beams and plates to compress the beams and plates against each. The flitch plates may be metal or fiber-reinforced resin and may further include slotted holes to allow the beams to retract lengthwise in response to environmental changes.

A first floor panel is provided that is connectable to a second floor panel in an array having a contiguous channel for retainably housing a cable. The array includes repeating units, each including one or more floor panels. The contiguous channel is formed through, between or through and between respective units. The first floor panel includes a body having a generally planar top surface, a bottom surface defining a bottom plane, and a first side. The first side includes an upper cable-retaining lip and a lower interlocking support. The interlocking support includes an interlocking support that is shaped to interlock with a corresponding side of the second floor panel to form a channel segment between the first side and the corresponding side of the second floor panel. The channel segment is adapted to retainably house the cable, spaced apart from the bottom plane. A modular flooring system is also provided involving a plurality of interconnectable floor panels.

A modular floor for providing support to a vehicle and/or a crowd on an uneven or soft subsurface of a supporting terrain is disclosed. The modular floor comprises at least two planks, each plank comprising a top and a bottom plate separated by a plurality of spacing plates. A first plank comprises a male connection element and a second plank a female connection element to interconnect the first and second planks. The connection elements are configured to extend a modular floor of interlocked planks both at an edge comprising a male connection element as well as at an edge comprising a female connection element. Preferably, a plank is a single-piece component, comprising aluminum alloy or plastic.

Mats and methods associated therewith are described. The mats include a main body defined by a plurality of sidewalls and two exterior surface walls opposing each other. The main body includes a pattern of internal walls that define internal voids within the main body. At least one primary structural support rib is arranged within the main body and extends between the two surface walls and from one of the plurality of side walls to another of the plurality of side walls. The at least one primary structural support rib traverses the internal voids defined by the pattern of internal walls.

A dump plate device includes a dump plate for supporting a vehicle adjacent to an edge at a worksite when dumping a load over the edge by the vehicle. The dump plate device further comprises at least one positioning device fixed to the dump plate, wherein each positioning device is configured to wirelessly transmit one or more plate position signals containing information indicative of an actual plate position of the dump plate.
