Scope
The Electricity Alliance East (an Alliance between National Grid and Balfour Beatty) approached Lyndon SGB to devise a safe method of delivering operatives, tools and materials to a work platform located two-thirds of the way up the structure for essential electrical and structural maintenance work.
Challenge
The exceptional height of the pylon, coupled with its light-weight construction and exposed riverside location placed significant restrictions on the access supplier. Brand Access Solutions was to use a specially adapted, 120 m high mast climbing work platform (Mastclimbers™) erected through the centre of the pylon.
Space within the tower was restricted, especially near the top where it narrows to just 5 m x 5 m. Brand Access Solutions therefore used a single masted unit with a platform small enough to travel up through the central frame to the platform. A key advantage of the mast climbing system is that it can be progressively erected from its own platform – without any additional access.
To support the slender lattice mast, Brand Access Solutions designed a special tie to take the weight and transfer the load safely to the pylon’s light-weight structure. Design engineers calculated that there is a need to use an unusually large number of ties to ensure the rigidity of the mast. Therefore a bespoke tie with 38 connection holes was designed.
