CompoTech and the University of West Bohemia in Pilsen succeeded in the public competition, TRIO 4, announced by the Ministry of Industry and Trade for the Hydraulic Composite Crane project.

Using epoxy/carbon fibre wound structural elements and integrated joints to be mounted on vehicles. The idea is to create a series of closed section telescopic beams made using filament winding and axial pitch fibre laying technology and integral composite joints.  The pins required in fibre winding are designed so that they create the accommodate the connection system of each beam. Thus each beam is made in one operation with the result reduce the need for machining or welding.

The structure will be a much lighter and equally rigid crane that should mean significant savings over the conventional steel structure despite the extra material cost of Carbon Fibre. The reduced weight should mean further savings during the lifetime of a vehicle through. Also less energy consumption will consequent reduction of emissions. Composites resistance to corrosion enables these hydraulic cranes to be used in marine or other corrosive situations with yet more environmental advantages.

The project will be financially supported by the Ministry of Industry and Trade of the Czech Republic.
