Description
The ‘Bunyan Striker’ was the original concrete finishing tool of it's kind. It essentially transformed, almost overnight, the manner in which concrete was laid down.
The Striker tube spins in the opposite direction of travel, creating a positive grasp of friction between the concrete and the underside of the tube, effectively cutting surplus material which itself rolls ahead of the tube towards the point of delivery. The action of the tube against the surface produces a kneading effect which in turn consolidates the top mat to an effective depth of some 2" (5cm). The tube,itself, does not provide any vibration, having a positive effect of leaving the major aggregate close to the surface where it is needed to provide durability.
Ancillary compaction with the use of internal poker vibrators is almost always recommended. Movement of the tube along the forms cleans these shutters ensuring that the concrete is always laid to the correct levels. This screeding machine will produce exceptionally high tolerances. It may be used for flatwork and inclined slopes of up to 60 degrees have been successfully achieved. Bespoke applications are a speciality and the Bunyan Striker has been at work on conical treatment tanks, canal ditch irrigation and has been notably employed on the High Speed Rail link currently under construction from Brussels to Amsterdam. Supplied in either petrol(gas) or diesel variants.
International sales and enquiries are most welcome and whilst working hard throughout the UK for major contractors this machine has been used as far a field as Dubai, Pakistan, Hong Kong and Namibia operating in extreme heat conditions which has proved how durable this machine really is.
