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.
Claims18
A laminated support mat comprising a plurality of laminates assembled into a desired configuration to define said mat, said mat having first and second contact surfaces;
- a plurality of bolts extending through said laminates for maintaining said laminates in said configuration;
- and at least one wear pad provided on said laminates for protecting said laminates from abrasion, said at least one wear pad extending across said first contact surface and said second contact surface of said mat.
A laminated support mat for placement on soft terrain and supporting equipment, comprising a plurality of laminates arranged in end-to-end and side-by-side relationship to define said support mat;
- at least one rubber pad provided on said laminates for protecting said laminates from abrasion;
- and a plurality of bolts extending through said rubber pad and said laminates in spaced-apart relationship with respect to each other and nuts threaded on said bolts, respectively, for securing said rubber pad on said laminates and securing said laminates together.
