ABSTRACT:
A mobile saw bench is designed for cutting elongate workpieces such as elongate open or closed steel sections. The mobile saw bench comprises a base structure which is mounted on four castor wheels. Formed continuous with the base structure is an intervening frame structure to which a benchtop is mounted. The saw is appropriately mounted to the benchtop to permit cutting of a workpiece which is located thereon. Importantly, the mobile saw bench further comprises a universal coupling. The universal coupling is mounted to an underside of the benchtop and is releasable clamped to an elongate member which is in the form of a rigid measuring staff. The universal coupling allows pivotal movement of the benchtop relative to the measuring staff which is stationary.
