Rail bonds are set in place using a specific hydraulic tool that is used to fix the bond in the rail by expanding the bushing.
Tool consisting of a calibrated manual hydraulic base and a pulling unit adapted to the thread of the bond to be set.
The tool and its pulling unit are identified by the same colour code. There is a colour for each setting force and the size of the bond to be set.
Easy to use : automatic release with an audible « click » when the setting force is reached.
Visual indication of the piston feed during crimping.
Removable handle, enabling a rail bond to be set in a restricted space (for instance, junction crossing).
A bushing remover (supplied with the tool) can be used to remove the reail bon if it has been damaged from externally.

The bonding connection system developped by Dubuis enables a mechanical and electrical connection to be made between a cable and the rail. This concept satisfies the increasingly stringent requirements of railway networks : reliability, result that is not operator-dependant, rail strength conserved. 

The bond is fitted with a hydraulic tool that, while holding the bushing in place in the rail, expands it by calibrated traction on the dowel.  In orange here, the contact surfaces and electrical connection surfaces.
