Parliament Station – South DRS Lifting Monorail System

The Southern Program Alliance engaged Cerecon to engineer a specialised lifting system for installing steel stair modules within the Parliament Station South Draught Relief Shaft. The shaft presented a unique challenge: a combination of diagonal and vertical sections, so each module had to transition seamlessly from an angled descent to a straight drop.

To overcome this, Cerecon conceived a dual winch system. The first winch was fixed at the start of the diagonal section. The second was mounted on a mobile steel cart that rolled along a monorail securely fixed to the shaft wall.

The first winch manoeuvred each load through the diagonal portion of the shaft, and the second lowered it through the vertical section. This approach ensured precise and safe installation of the steel stair modules despite the shaft’s complex geometry.

By combining structural engineering expertise with inventive problem-solving, Cerecon enabled the efficient installation of steel modules in one of the project’s most constrained spaces.
