The Multiple Core Barrel is used to install barriers with anchor plates on the bridge board guardrail. 

The Multiple Core Barrel can be adapted to every kind of barrier, thanks to the possibility to change the centre distances.

The diamonds tools allow perforation of every concrete condition. Tool lubrication is provided by a hydraulic pump, applied on the equipment.
