Rope and Sling Specialists (RSS) has supplied a 36 m-long lattice beam and rigging equipment to support the Cefn Saeson School construction project in South Wales.
Davies Crane Hire used a 100-tonne capacity Grove GMK4100L mobile crane to lift roof sheets, measuring up to 35 m long, at the project site.
According to Jack Sleeman, health and safety coordinator/hire and sales at RSS, the configuration of the crane involved two 22 m-long outermost wire rope slings and two 18 m-long wire rope slings inside them.
A 13 m-long wire rope sling was rigged in the centre with a two-leg chain sling beneath it to utilise two pick points on the lifting beam. Six chain slings with shortening grabs completed connection to the lattice beam, while beneath it, 38 two-tonne capacity shackles and 19 one-tonne capacity synthetic slings were wrapped underneath the roofing sheets.
