A new type of jack was developed in recent years: the Long-Stroke Jack. The jack was designed to reduce labour-intensive jacking involved in moving stacked materials and facilitate rapid completion. The dual-action hydraulic lifting jacks featuring locknuts have a lay of 1,600 millimetres, a pressure capacity of 400 tonnes, a traction capacity of 100 tonnes and an installation height of 2,820 millimetres.
The hydraulic jack was designed for lifting and lowering at a height of approximately 1.20 metres, guiding (absorbing horizontal power) and fastening.
The Long-Stroke Jack already proved its worth in previous projects on the Betuweroute (BR 3 and Kijfhoek). In these cases, elevated construction was used for the railway surfaces, which were then lowered onto the final bearings in a single movement using the Long-Stroke Jacks.
