Uprighting of Columns, Chile
ALE was asked to undertake the uprighting of two columns at the Mejillones Power Plant in Antofagasta, Chile.
Using two 45-metre, self-stabilising ‘A’ frame gantries, ALE successfully lifted and tailed two columns into the vertical position. Each gantry was provided with a 200te lifting unit and an auxiliary lifting unit for stabilisation and retention. The columns, measuring 85 metres long, were both manoeuvred upright and positioned on their foundations within five hours.
