The two Alloy Space Frame platforms (cradles) were moved to the centre of the East Walkway on Saturday night to allow the cruise ship, Silver Cloud to pass through the raised Tower Bridge.
Alloy Space Frame platforms
Two teams of 4 ALPS operatives carried out the platform traversing operation, which involved the removal of the four rear hangers, then propel the platform forwards using 2 hauling and 2 restraining hand winches, then reinstate the rear hangers. This procedure was continued until each platform was in the desired location, where storm anchors were then fitted and the trolley brakes applied.
