Zoomlion Heavy Industry Science & Technology has deployed two of its R4300-200 tower cranes to support the final construction phase of the 283m Shangri-La-side main tower at China’s Lugu Lake Grand Bridge.
The topping out, which took place on 29 September, relied on the cranes’ capacity to lift and accurately position large structural components within a mountainous terrain on the Xichang-Shangri-La Expressway.
Each crane was responsible for the heavy lifting on its assigned main tower, particularly during the last 103m of assembly.
According to Zoomlion, the placement of steel and concrete sections above the main crossbeam required enhanced stability and meticulous load control, especially as crews contended with variable wind conditions.
Equipped with an 80m jib and a lifting capacity of up to 200 metric tonnes, the R4300-200 cranes incorporate over 20 integrated safety and control functions.
Features such as collision prevention, automatic speed regulation based on load, and anti-drift load control supported safe and steady operations.
Operators were able to conduct remote lifts using live video feeds, which allowed for ground-level monitoring and precise alignment of sections during installation.
The company reported that all lifts for the Shangri-La-side main tower were completed safely.
Elsewhere, Zoomlion adapted its equipment to meet the demands of the Central Bank of the Republic of Türkiye tower, a 380m structure within the Istanbul International Financial Centre.
On this high-rise project, customised L760-50 luffing jib cranes facilitated more than 1,200 heavy lifts in a space-constrained environment.
The custom approach applied modular mast sections for transport efficiency and multiple tie-ins engineered for seismic compliance.
Zoomlion stated that control systems on the Istanbul site enabled precise alignment of structural components and mitigated load sway, while continuous wind monitoring and automatic safety warnings contributed to operational safety.
Remote monitoring transmitted live data on crane performance, supporting ongoing maintenance and troubleshooting with engineering assistance from China.
Support further included studies on crane placement, assessments of installation feasibility, and simulations for dismantling, aligning equipment specifications with the practical demands of the construction site.
The project also informed Zoomlion’s work on other high-rise developments, including the 377m Ciel Dubai Marina hotel, Dubai’s 400m Al Habtoor Tower and Indonesia’s 331m Oasis Central Towers.
