Late last year, we took delivery of a new Liebherr LG 1750 lattice boom mobile crane. The seven-figure investment supports AIS Wind Energy’s vision to provide a turnkey approach to managing the construction of onshore wind turbine installation and carrying out necessary decommissioning, service and repair works – efficiently and cost effectively.
Here, Andrew McGlade, managing director of AIS Wind Energy answers your key questions about the crane and explores its incredible capabilities.
Q: What are the key benefits of the LG 1750?
A: The LG1750 offers fantastic versatility amongst other models of heavier cranes. It retains the strength of modern crawler cranes while offering the flexibility afforded by the quick mobilisation of a conventional mobile crane.
Q: What sectors is the crane designed to support?
A: The LG 1750’s design has evolved during its 18 years of production, making it ideal for fast erection work across heavy industrial construction and infrastructure, port handling and the wind energy sector.
Q: What is the cranes load, reach and lift capacity?
A: The crane is available with a wide selection of boom configurations, including SX boom system optimised for lifting wind turbine components and can be tailored to suit the majority of any project demands and constraints. The powerful product has capacity to lift 400t at 20m radius and up to 105t at a 165m hook height and 34m radius on SX configuration.
Q: How heavy is the LG 1750?
A: The chassis travels to site with all four outriggers at a total weight of 96 tonnes. If required, the outriggers of the LG 1750 can be removed, thus reducing the weight to 48 tonnes.
Q: How long does the LG 1750 take to mobilise?
A: This depends on the setup and configuration of the project. For a standard configuration, setup and derig can take around three days. For a more complex setup where the crane is operating at full capacity, it’s around four days.
Q: What makes this a green investment?
A: As the green energy sector continues to grow, wind turbine OEMs are installing ever heavier and higher turbines. The LG1750’s height and radius capabilities provide the capacity we need to meet market requirements as they evolve and to mobilise and demobilise turbines efficiently.
It will also help us reduce transportation costs and carbon impact compared with current crawler crane demobilisation expenditure and operate within tight restrictive sites, all while offering strength and capacity on a mobile chassis.
Q: Where is the LG 1750 sited?
A: AIS Wind Energy’s LG 1750 has been initially sited at the Sandy Knowe Wind Farm, where it is completing a 15 turbine increase to the current site’s portfolio of turbines in the Scottish Hills of Dumfries.
The crane is already fully booked for projects in 2024 across the UK. Beyond this, it has it’s sights set to be utilised in Ireland, Scandinavia, Germany and beyond.
