A concrete kerb forming machine (10) has a hopper (11) for receiving wet concrete (12). The concrete is extruded through a tunnel-shaped mould (15) by a pusher plate (13) to form kerbing having a sectional profile matching that of the mould (15). The mould (15) is reversibly mounted to the machine (10). Side skirts (17) can be mounted to the bottom of the hopper (11) to accommodate moulds (15A) of greater height. The machine (10) has a pair of steerable wheels (21) whose steering arms (22) are connected by a steering link (23) of adjustable length. The wheels may be locked in a particular orientation. The steering and wheel assembly is mounted on a rail (35) which is laterally adjustable relative to the body (36) of the machine, enabling the machine to operate adjacent walls. Pivotally mounted height adjustment handles (32) are also provided on the machine (10) to allow the handles to be rotated even if in close proximity to a wall. |
