Dubai’s skyline just got a serious upgrade. Raimondi Middle East has pulled off a regional first by deploying its highest-ever climbed luffing jib crane — the LR213 — now towering at 322 metres.
Working on a 75-storey premium residential tower in Dubai, the LR213 isn’t your average crane. With a 50-metre jib and a 3.3-tonne tip load, it’s been installed on an existing steel undercarriage, a move that required precise engineering due to space constraints and foundation limitations.
Here’s the twist: the crane had to replace an earlier one after the building already reached 100 metres. This meant Raimondi’s team had to work with an existing foundation, which limited how much weight the base could handle.
Instead of designing the foundation around the crane — the usual approach — Raimondi flipped the script. Engineers adapted the crane’s setup to match the structure’s load limits by using a 6×6 base and carefully removing ballast blocks as the crane climbed higher.
The LR213’s structure is built from GR5S mast elements — two large 11.8-metre sections plus a hundred smaller ones, each just under 3 metres. Twelve bracings keep the towering structure stable. Collar positioning was another big challenge. It needed multiple design changes, complex calculations, and serious precision to get it just right.
Raimondi’s Wael Hasan summed it up: “This project demanded innovation at every step — from recalibrating the base to repositioning collars. It’s a showcase of our engineering edge.”
The crane won’t be up forever. Dismantling is set to begin soon, with the LR213-14t to be lowered to 50 metres before being removed by mobile crane.
