TOWER CRANES Ӏ JOBSITE INSIGHT
that the project has total coverage
over both boiler lines with the capacities required.
What is it about Marr’s solution, or the M2480D, that helped win the Lostock contract? Marr’s solution for this project helped to reduce complexity while at the same time delivering the lifting requirements needed. This translated into a number of key aspects: Addressing the challenge of a constrained site, we have maximised the available space by designing a modular rail system for one crane and a fixed foundation for the other. This freed up space for storage and pre- assembly areas whilst still achieving the capacity, volume, reach and coverage required; The programme demanded a mix of high capacity lifting and high volume to support the general construction activities. These aspects are essential for schedule achievement; and The M2480Ds are rated to operate at up to 20m/s – providing the project with outstanding availability and the platform for increased productivity and efficiency.
What are the crane’s vital statistics? See M2480D specifications and data sheet at
www.marr.com.au/cranes/ m2480d/
In total how many M2480Ds does Marr have in its fleet? Undisclosed. We prefer not to share the details of our fleet size but can say that our M2480D fleet has grown substantially in recent years to support current and future demand, particularly for our heavy lift fleet. Clients are increasingly choosing to engage with us early to secure availability.
Where were these two M2480Ds shipped to the Northwich plant from? The cranes and their components came from different parts of the world including Australia, Turkey and the UK.
How easy/difficult is transportation of the cranes? How long did it take and how many vehicles did it involve? Does Marr provide these transportation services or did it outsource them? The transportation of our cranes is a complex multi-modal process. Marr works with haulage and shipping professionals on bespoke solutions for
each crane involving a minimum of 56 trailer loads from our laydown facility to site.
At the Lostock jobsite why is one M2480D on a Marr Transit System (MTS) rail system while the second M2480D is installed on a static base? Simply to support the project requirements for capacity, reach and coverage.
What will the heaviest lifts onsite be? The cranes are installed with a configuration that allows lifts up to 220 tonnes and a reach of up to 73 metres. Some of the planned lifts include the 70-tonne steam drum and boiler waterwalls weighing 85 tonnes.
Are there many other cranes or infrastructure on site that the luffing jib tower cranes need to avoid? If so, how is collision avoidance ensured? Most construction sites are complex by nature and constantly evolving. Marr cranes use anti-collision software and can programme zones of operation to ensure avoidance of impact to plant and infrastructure.
How long are the M2480Ds expected onsite and what happens if the job is delayed?
The terms of our contract are commercial in confidence with our client. We work closely with our clients to support their programmes and are generally able to flex our dates to support their needs.
Where are the cranes going after this job? Marr has a number of yet-to-be announced UK projects on our order book, but we are unable to disclose the details of those projects at the moment. The global trend towards Modern Methods of Construction (MMC) and Designed for Manufacture and Assembly (DfMA) is resulting in increased demand for Marr’s heavy lift luffing tower cranes in the UK, Australia and other parts of the world, so we are working closely with our current and future customers to ensure a seamless transition from one project to the next.
