Lifting and weighing a 150-year-old railway bridge for a thorough renovation

Prior to completing a restoration project, it is important to determine the weight of the main object. Lifting and weighing a 150-year-old railway bridge on the former railway line Ljubljana-Planica (Slovenia) was part of the complete renovation project. Commissioned by the State of Republic of Slovenia, Holmatro’s partner Prolitech d.o.o. delivered Holmatro Short Stroke Cylinders HSC 100 S 5, FlowPanel Control Manifold HMS 4 C and Extension Hoses VL 5 SOU.

Situation

A 150 year old railway bridge on the former railway Ljubljana-Planica was up for a thorough renovation. The bridge needed to be lifted from its foundation for weighing. The railway track built by Rudolf’s Railway (K.K.priv. Kronprinz Rudolf Bahn) opened in 1870. In 1873 the railway provided a connection with Villach (Tarvisio–Villach). The railway received various names like: Gorenjska line, Rudolf’s railway and Planiška line. In 1999 the former railway was transformed into a popular bike trail.

Challenge

Prior to starting the renovation, it was important to weigh the bridge. Lifting the bridge from its foundation needed to be done with high precision. 

Solution

To lift the bridge with high precision, Prolitech chose multiple Holmatro Short Stroke Cylinder HSC 100 S 5, a FlowPanel™ Control Manifold HMS 4 C and multiple Extension Hoses VL 5 SOU. It is important to use the right equipment in combination with controlled power and Holmatro equipment was the perfect fit. The bridge was successfully lifted and weighed. The weight of the bridge is 130 t.
