Air lift for sky bridge

Posted on by in News

Three large 18m-long steel sections, which form Heathrow’s T5 skybridge, have recently been lifted into position with the aid of a 500t capacity crane.

Each weighing in excess of 20t, the plate girders together with their intermediate sections were fabricated on site by Watson Steel Structures.

The skybridge links twin lift towers from the railway station and car park to the main T5 departure gates.

Tony Whitten, Watson Steel Structures Contracts Director said the bridge has been dubbed the ‘letterbox’ because it fits into a hole in the main terminal building. “Each section was erected with an attached temporary workplatform so other activities could be carried out,” Mr Whitten said.

Once in position, further steelwork will be installed to support the sides and lid of the bridge. “All of this architectural steelwork is exposed,” Mr Whitten added.

The skybridge is part of Watson Steel Structures’ on-going T5 steelwork contract.
