Mr. Tim Andrews, Managing Director, Arrow Machinery
Stronger: The use of wet mix (40mm+ slump) vibrated concrete produce a much stronger (in excess of 30mpa using a grade 25mix), and more durable finished Kerb. At 40mm slump optimum cement/water ratio is achieved assisting the hydration process. The compaction achieved by the vibrators increase the density of the concrete in turn increasing the strength and integrity of the Kerb.
Faster: Up to 15 lineal meters per minute can be achieved straight out of the machine taking only 12 minutes to discharge a truckload and achieving just under 500mts of finished Kerb per day with a 2 man crew.
Economical: Jobs can be completed ahead of time as the backfilling and associated earthworks can be done the very next day. Slurry materials and manpower are not required as the finished Kerb comes straight out of the machine.
ARROW MACHINERY, Australia's only commercial manufacturer of Slipform Kerb machines produces 2 models- the ARROW 350 MINI SLIPFORM KERBER and the ARROW 750XL SLIPFORMER.
The benefits of the Australian made ARROW 750XL is that it is a compact machine fed directly from the transit mixer, no augers or conveyors required unlike the larger US or German made machines. The ARROW 750XL is small enough to fit on a standard 6-ton truck or trailer, so does not require semi trailer/low loader transport or oversize permits yet has the power and capabilities to pour footpath up to 1500mm wide inboard, vee drain up to 1200mm wide offset and Kerb sections up to 700mm high.
