CALEMATIC SECURITY SYSTEM

The Calematic safety system is a kit consisting of a prefabricated concrete pit and iron wedges moved by pneumatic pistons. It must be installed in front of the loading bays and its wedges must stand up and lock the wheels of the vehicles during work. The pit is already supplied as standard in a single block with seats for the wedges in the upper part; in the heads of the lower part, there are special holes for the passage of compressed air pipes and for the drainage of rainwater. The wedges are made of steel sheet 10 mm thick. Hot-dip galvanised; they are driven by strong hydraulic cylinders with a diameter of 63 mm. Each system needs a pressure of 6 Bar that feeds the cylinders themselves. The configuration can be 8 wedges in a single pit working on one side of the truck; or 5+5 wedges, in two separate pits, on both sides of the truck. The wedges are high and effective so as to ensure that vehicles are blocked, but do not interfere with mudguards or other truck equipment. The very shape of the wedges has been designed so that they do not have any roughness or dangerous edges that could cause cuts or punctures in the tyres. When the system is in the rest position it is coplanar to the flooring and therefore the manoeuvring areas remain free and unobstructed. The use of compressed air creates an ecological and environmentally friendly system, no risk of oil leakage. It is a system that can work in any weather condition and does not require any kind of maintenance. In fact, there are no motors or bearings to grease, nor chains or sprockets.
