Kobelco has announced new cranes in its G series
equipment. It has its own
80,000 sq m fabrication yard, in the Mina Salman port area. Al Jazeera Shipping managing
director Ali Hasan Mahmood went shopping for a new crane in 2022 and, after considering his options, selected the LR 1400 SX. One standout feature for a man known as the ‘King of Barges’ was its capability to preselect barge inclinations, which automatically applies the permitted load curve. Since May 2023 the LR 1400 SX has been working on multiple projects with Bapco at its refinery in Bahrain.
WIDENED BOOM Users of cranes like this are seeing increased need for larger, multipurpose cranes. That has driven Liebherr Nenzing’s development of the new LR 1400 SX, which shares a design concept, and even some parts, with the LR 1300. But another approach is to increase the capacity of existing multipurpose cranes. And that is what Manitowoc has done with its new wide boom inserts for the MLC 300 VPC MAX. A crane like this already

a maximum boom length of 429.8 ft (131m), with a tip height of 452.2 ft with the extended upper boom point. In addition to the longer boom lengths, the extra 30% capacity allows contractors to respond to the trend for taller, heavier wind turbines while continuing to enjoy the benefits of operating smaller cranes. Lomma partnered with JMS
Crane & Rigging to install it on an MLC300 VPC-MAX for maintenance work on multiple wind tower sites across the upper Midwest. “We are excited to have been a part of the kit’s development and now see it at work in the field. It radically expands the use of the MLC300 for
renewable energy jobs,” says Steve ‘Burkey’ Burkholder, heavy lift manager at Lomma. “Now that 89-, 90- and
95-metre towers are becoming more prevalent, we would have to rely on our larger Manitowoc Model 16000 or add a luffing jib to our MLC300 if Manitowoc hadn’t answered our prayers for the Wide Boom Plus kit,” says JMS vice president Rich Johnson. “It also enables a much friendlier crane build, with a smaller footprint, and saves us around 16-20 hours in assembly and disassembly time per job. Given that we might do that 300 times a year, it's a major benefit to us.”
EMISSIONS REGULATIONS It is rare and notable to see a heavy lift crawler operating in a city centre. But for mid-range multipurpose cranes, work often takes place close to homes, schools and workplaces. In many cities, mayors and local
councils will impose requirements for cranes with newer, lower emissions, engines. And in Europe the regulations for non-road mobile machinery have tightened with the new Stage V rules beginning to take effect in 2019/2020 and a two-year transition period, during which manufacturers could install older engines from their stocks, coming to an end in 2022. That has driven the
development of a range of upgraded cranes, with engines compliant with the new regs. Kobelco announced three
new cranes in its G series in late 2023. These consist of the 100t CKE900G-4, the 150t CKE1350G-4, and the 250t CKE2500G-4. The two larger cranes have been absent from Kobelco’s line up for two years, and will return this year, with their new 270kW Stage V compliant Isuzu engine. The smaller
