ABSTRACT:
A machine for laying reinforcing mesh for concrete comprises a pair of spaced front wheels and a pair of power driven rear wheels. Several different forms of devices are provided for lifting the roll of reinforcing mesh and positioning it between the front wheels. From that position the wire is unrolled from the top of the roll and passes back under the rear wheels, thereby backbending the mesh as it is unrolled. In other embodiments not employing the front wheels, a pusher in front of the power driven wheels pushes the roll ahead of it along the ground as the latter wheels move along the mesh. In such embodiments hooks are provided on the pusher for engaging the roll in a manner such that, before unrolling, the roll may be lifted and transported to the desired location for unrolling. The safety hook is provided to the rear of the wheels to prevent the trailing edge of the non-backbended mesh from the roll from springing into the operator as the wheels move off that trailing edge.
In one of the embodiments, various types of mesh laying devices are attachments to a power head comprising a pair of wheels, a transaxle, a motor and handlebars. Various other power driven attachments useful to concrete contractors can be used on that power unit alternatively with the mesh laying device. Such alternative power driven tools include a saw for cutting the upper surface of a concrete slab or the like, a grinding head for grinding the upper surface of a concrete slab, an air compressor, a trencher, etc.
