Challenge

The Hanzebrug, located on the Hanzelijn near Hattem, is an impressive steel railway bridge that can expand or contract when exposed to temperature differences. This makes it necessary for the cables and pipes that supply the bridge with energy and communications to be routed flexibly and protected. The bridge structure can vary in length by up to 8 meters, which places high demands on cable management.

Approach

Wisman Techniek developed and installed two specially designed Cable carriers precisely meet the requirements of the Hanze Bridge. The Cable carriers, which are constructed in three different height levels, ensure that the cables are properly supported, guided, and protected when the bridge expands. During installation, a separation was also created between data cables and electrical cables, which contributes to safety and efficiency.

Because the cables had already been pulled, it was particularly challenging to build the Cable carriers around the cables Cable carriers site. Wisman Techniek also designed special mounting brackets that attach the Cable carriers to the bridge Cable carriers a robust and stable manner.

Result

The installation of specially designed Cable carriers the flexibility and protection of the cables on the Hanze Bridge, even when the bridge moves significantly. The bridge can now continue to function safely, without the cables being at risk of damage due to expansion or contraction of the structure.

This solution ensures reliable operation of the bridge's electrical and communication systems, guaranteeing the long service life of the cables and safe conduction under extreme conditions.
