LUFFING JIBS Ӏ TOWER CRANES
These are not, however, niche
markets. Urbanisation has been the dominant trend of the post- war, post-colonial world. In 1960, the UN reports, around
a third of the world’s population lived in cities. By the millennium, that had reached 47%, and in the latest figures, for 2021, it stands at 56%. That’s more than half of the world’s 9bn or so people, all of whom will want to be close to a public transport hub and local shops, schools, and entertainment venues. Anyone who has stood on the banks of the Thames, in Central Park, or on Shanghai’s Bund, will know what that means: a forest of skyscrapers. And those skyscrapers will very often need luffers to build them. The crane industry has
Select orders four more Terex luffing jib tower cranes
UK-based Select Plant Hire has ordered four new Terex CTL1600 luffi ng jib tower cranes – bringing its fl eet total of CTL1600s to nine. Terex Tower Cranes says this makes it the largest and newest fl eet of these cranes in the world. According to Terex, its CTL1600 is a popular choice for construction and
rental companies globally and is well-suited for high-rise buildings on urban job sites. With a maximum capacity of 66 t (72.8 USt) and jib length of 75 m (246 ft) it is the biggest luffi ng jib crane in its range. It is also equipped with features including T-Torque slewing technology, Terex Power Plus, and Terex Power Match. Terex Tower Cranes says, due to its heavy capacity, the CTL1600 is in high demand in the UK – especially for heavy lift requirements such as precast and other projects that incorporate offsite manufacturing and modern methods of construction, with Select Plant Hire identifying particular demand for using these cranes coming from the waste-to-energy and data centres being commissioned across the UK.
Potain’s MR 229
responded to this surging demand for the high life, with cranes that can reach great heights within tightly limited radii. The last year has seen a wealth of new models to suit every need. At Bauma Liebherr and Wolffkran, two of the leaders in the field, had luffers on display: Wolffkran had the 235B, launched in 2020, able to lift 4.1t on a 50m jib; and, as we saw in the fibre rope article in this section, Liebherr launched its first fibre rope luffer, the 258 HC-L 10/18 Fibre.
BENCHMARK LEVEL The 700tm capacity class has become the benchmark for rope luffer manufacturers. It gives the power needed to pour at pace, particularly in tall buildings where concrete can set in the bucket before it reaches the working floor; and allows for large steel and concrete modules to be lifted and, when used with a second rope, manipulated with ease. If you want to build hundreds of metres into the air, over an awe-inspiring multi-storey atrium, it’s the class of crane you need.
