Arrow’s Slipform machines, the contractors’ choice
At Excon, Arrow will be displaying its full range of Concrete Kerb Casting and Slipform Kerb machines. The Arrow 750XL Slipform Kerber, the contractors’ choice for all major national highway projects, and the Arrow 770 Kerbmaker for use in townships, residential and car parks, will be highlighted.
770 Kerbmaker gives first-class results with even unskilled labour
The Arrow 770 Kerbmaker eliminates all types of formwork and guide rails and produces a first-class result with comparatively unskilled labour. Propelled forward by a special action, it extrudes compacted concrete at the rear. The accuracy in both line and level is easily maintained by use of a guide line and pointer.
The automatic machine incorporates the basic functions of manual hydraulic controls with the facility to select automatic cross level, plus, automatic line and height controls. Conversely, manual control may be achieved by isolating the electrical circuits with the switches provided.
The machine is powered by a flexibly mounted 16hp synchro-balanced petrol engine with duplex chain driving the heavy-duty reduction box and rugged ram mechanism.
With the Kerbmaker, a small operating team of three men (minimum) will produce high strength kerb and channel at a maximum rate of approx. 2 metres per minute, using 5-10 mm maximum slump concrete with maximum water content for that slump.
The primary unit may be used with interchangeable moulds to provide median strips, barrier kerb, mountable kerb, kerb and channel and footpath (slab) in many sizes.
The Kerbmaker is designed to extrude shapes having a maximum width of 690 mm and in the region of 2600 square centimetres of cross sectional area.
Widening kits for the primary unit are necessary to use moulds having widths from 691 to 1220 mm.
Two screw jack operated wheels allow the machine to be set up for initial forming and for transporting around the job site. The Kerbmaker cannot be towed behind a prime mover, as serious damage could occur to the wheel support system.
The Automatic Kerbmaker with hydraulic/electric system, comes complete with sensor box to automatically follow the stringline, at the same time, maintaining automatic height and cross-level control.
The moulds for the extruded concrete, engine, gearbox and ram operating mechanism are the same for all three models and are interchangeable. The drive engine mentioned is a twin cylinder 16hp Briggs & Stratton 4 stroke petrol engine fitted with 12 volt electric start and charging system.
All moulds are custom-made to order and are not normally carried in stock because of the multitude of cross sections required by the various authorities. All moulds are fitted with a slurry/grout hopper as standard.
An essential tool in the operation of the automatic machine is the stringline peg and assembly. These are specially designed and consist a sliding block assy extending arm and stringline holder made to suit a 19 mm x 916 mm long steel peg. 100 of these assys and pegs are required and can be supplied extra.
We are enhancing our presence in India
We plan to further enhance our presence in India in the not too distant future to provide better service to our customer base. We understand that the effect of the Bharatmala initiative of the government will have a huge impact on the road construction sector, and as was with the Golden Quadrilateral, the ARROW brand of kerbing machines expect to play a role in the construction of concrete kerb on the highway projects.
We are looking forward to our participation at Excon this year and welcome all our old customers as well as the new players in the road construction business to our stall (B 200) in the lower level of Hall 3.
