Contesub Spear Truck Performance - Pair
Price is for a pair of Contesub Spear Truck Pulleys. This is a specially designed pulley system for containing, organising and bearing the load of rubbers for invert-pulley roller spearguns. This pulley system is optimised in its entirety to ensure maximum performance and reliability. Pulleys can be separated on round barrelled spearguns or used in flat bellied spearguns close together as well.
The pulley, turned from solid by bar of a special polymers, is characterised by a deep-angled groove that offers the line the maximum adherence in its interior: in this way it prevents the line slipping on the pulley
Contesub Spear Trucks use a CAD modelled pulley system, manufactured with the help of new technologies. It is a reference point for those looking for the best solution for a speargun requiring added leverage.
The rubbers are joined to the carriage by means of three cylinders with an hourglass shape, ensuring a symmetrical load and perfect alignment with the structure.
The frame is composed of two 1.5mm, stainless steel, laser cut plates to minimise the overall weight of the part. The 5mm 316 stainless still axle of the pulley is a "pass-through" type in order to be able to support any load without compromising the functioning of the structure.
It can mount up to 4 rubbers, with provision to optimise and maintain their correct positioning. Simplify attaching multiple bands and eliminate the added weight length and comlication of shackles.
A pulley system for anyone intending to build a very high powered invert roller speargun.
