Installation of a railway bridge, UK

Overview

ALE has successfully installed the new Manston Lane railway bridge, consisting of nine 30m W10 PCC beams; seven inner beams, weighing 70t each, and two edge beams with precast deck included, weighing 140t each, Leeds, UK.

Services Required

Due to the high frequency of the trains on the tracks, ALE could only work for five hours overnight on Saturdays so had to efficiently maximise the time on site.

ALE lifted each of the nine beams using a crawler crane with a 105m boom.

The use of this boom enabled ALE to use a crawler crane, which provided additional capacity without the need for a larger crane.

ALE designed a rigging system that incorporated a pneumatic hoist to lower one end of each beam. This enabled ALE to move the beam while keeping it level. The angle of the beam was then adjusted to ensure both ends of the beam were placed on both abutments simultaneously.

The installation of the Manston Lane railway bridge marks the start of the new Manston Lane Link Road, a key piece of infrastructure, which opens up transport connects within north and east Leeds to Junction 46 of the M1.

ALE completed the operation in less than two months.
