A complex high-rise dismantling project in London, carried out by King Lifting, highlights the precision and planning required for crane operations in dense urban environments.
A Jost JTL 168.8 luffing jib tower crane, positioned 113 metres above ground near Canary Wharf, was safely dismantled using a carefully engineered lifting strategy. The constrained site, surrounded by high-rise buildings and busy transport routes, required meticulous preparation and coordination.
Detailed CAD modelling played a central role in planning, allowing engineers to determine optimal crane positioning, lift sequencing and clearance requirements. The primary lifting was carried out using a Liebherr LTM 1650-8.1 with an 80.5-metre luffing jib, supported by an Liebherr LTM 1090-4.2 for auxiliary operations.
Given the limited footprint, bespoke solutions were required, including specially designed outrigger mats to manage ground conditions and hybrid assembly methods to safely build and dismantle the crane components.
Urban constraints added further complexity, with every lift carefully choreographed to avoid nearby structures, overhead lines and street-level activity. Systems such as the Y-Guy were closely managed to ensure safe clearance throughout the operation.
Despite challenges including weather and evolving site conditions, the project was completed on schedule.
“A key factor in the success of this project was the close collaboration between all teams involved,” said Adam Catchpole. “Clear communication and precise coordination ensured that each phase was carried out safely and efficiently.””
