30 Second Takeaway
Ainscough Crane Hire has completed a highly complex rooftop lifting operation at Royal Derby Hospital, supporting Skanska with the installation of new chillers and a prefabricated plant room. Using a 500-tonne crane fitted with a 77-metre luffing fly jib, the team delivered the lift safely in a live hospital environment completing the operation ahead of schedule despite tight clearances and challenging ground conditions.
Supporting Critical Healthcare Infrastructure
Ainscough Crane Hire was appointed to support Skanska on essential upgrade works at Royal Derby Hospital, part of University Hospitals of Derby and Burton NHS Foundation Trust. The scope involved lifting a prefabricated plant room, two chillers, and associated steelwork onto the hospital roof all while maintaining uninterrupted hospital operations.
Given the live healthcare environment, safety, precision, and programme certainty were paramount throughout the operation.
High-Capacity Crane Configuration
The lift was executed using a 500-tonne crane equipped with a 77-metre luffing fly jib, providing the reach and control required to access the rooftop installation point within a constrained site footprint.
Mobilisation began on Friday night, with a ten-hour rigging operation carried out using a 60-tonne rigging crane. The setup was led on site by Bob Beardmore, Ainscough’s Heavy Cranes Technical Manager.
Engineering Around Tight Clearances and Ground Conditions
Working on a gradient introduced additional complexity. The Ainscough engineering team designed a bespoke ground solution incorporating:
An ekki timber mat ramp
Standard crane mats
Load distribution measures accounting for a nearby underground service chamber
During rigging, clearances were reduced to just 100 millimetres, highlighting the accuracy of both the engineering calculations and on-site execution.
Live Site Management and Safety Controls
To protect patients, staff, and the public, a significant section of the hospital car park was temporarily closed, with a full exclusion zone maintained throughout the lifting operation.
The 500t crane slewed each load into position, while a specialist contractor skated the plant room and chillers into their final rooftop locations.
Planning, Engineering, and Execution
The project was underpinned by extensive preparatory work from Ainscough’s planning and drawing office, including:
Multiple site visits
Detailed lift plans and method statements
Comprehensive risk assessments
Temporary removal of street furniture
Marcus Leyshon coordinated the planning and documentation process, while Mark Brown supported lifting tackle selection and configuration. An eight-point lift arrangement was engineered to accommodate the offset centre of gravity of the loads.
Despite the complexity of the operation, the lift was completed several hours ahead of schedule.
Industry Expertise in Action
Bob Beardmore commented:
“This was a highly challenging lift in a constrained, live environment, but the teamwork between our site crew, planning office, and the client ensured a safe and successful outcome. It’s a great example of Ainscough’s engineering expertise and commitment to delivering complex projects safely and efficiently.”
