  • Patent number: 6214428
    Abstract: A laminated support mat for supporting and moving draglines and other heavy equipment in muddy, boggy or marshy areas. The laminated support mat includes multiple wooden laminates of typically unequal length and selected width and thickness, which laminates may be fitted with one or more wear mat or pad and are bolted together to define a support mat of desired dimension, the laminates preferably constructed of oak wood for good strength and durability. The laminates may be constructed of scrap wood and conventional cable loops may be provided on each end of the laminated support mat for locating the mat in a desired position. Where the typically rubber wear pad or pads are used, the pads may be mounted on the laminates using a pair of channels that receive the bolts securing the laminates together.
