WASTE TO ENERGY PROJECT

Working closely with our client’s construction team during the early stages of the project, we were able to design a simple craneage solution that reduced the number of cranes required. This reduced congestion onsite and allowed for pre-assemblies at ground level, which reduced the number of activities at height and improved onsite safety.

We also completed an analysis of historical wind data which indicated that the project was at risk of having its crane lifting operations impacted by wind on 75 per cent of days across a 12-month period if a traditional crawler or mobile crane methodology was adopted. This figure increased to over 90 per cent of days being wind-affected during the summer months – highlighting that a different approach to lifting was required if the project’s craneage solution was to be successful.

Marr’s solution – using a 330-tonne capacity M2480D Heavy Lift Luffer (HLL) stood on one of our ballasted static bases and crane mat system – allowed critical lifts, weighing up to 150 tonnes, to be completed by a single crane from a fixed location. With a total site coverage of over 32,000 square meters and an ability to place 25 tonnes anywhere within the crane’s 102-meter radius, we were able to open up areas of the site for pre-assemblies and lay-down. This helped to significantly reduce congestion across the site.

The ability of the M2480D to work unaffected in wind speeds up to 20 meters a second, (which is double that of a traditional crawler or mobile crane approach), meant that we could de-risk the planned lifting operations from the delays that we had identified early in the crane planning process.
