RESTORATION OF INTERVENTION
The restoration work began with the lowering, using special equipment (manual hoists, wire ropes, etc.) Of the three bells installed in the bell tower and the entire support structure of the same (also called castellatura). Everything was dismantled and brought in our factory in Cologne (BS) for audit operations and budgeted restoration.
The project involved the study and design of a new castellatura fully cushioned support with anti-vibration buffers, capable of limiting the stresses and loads them between the support structure and the masonry of the bell tower.
Once arrived in our workshop the bells were subjected to a thorough review that included:
- The replacement of the three wheels, suitable for the transmission of motion between the motor and bell but in this case, having also the manual handling, the wheels are capable of handling both manually and in the bells electrified manner;
- The complete replacement of three insulators, made of strong wood (oak oak type) naturally seasoned. The insulators are completed with the relative support hardware;
- The complete replacement of the three clappers, steel and manufactured in accordance with a manual forging and then recovered in the furnace and suitably sized and painted.
As regards the electrical part of automation of bells we proceeded with the complete replacement of the system of handling of the bells, with the installation of RCTouchBell, handling plant for more advanced bells in the world, able to reduce fuel consumption and improve performance ensuring protection from electrical phenomena and power surges. Product we produce. For the connection of the plant and equipment it proceeded with the installation of a new power line pillar and driving force.
They have been replaced all three engines and installed three new elettrobattenti.
Work performed in accordance with safety regulations and impiagati materials.
