model, the CKE900G-4 builds on the design of the existing CKE900G-3, and has been available since October 2023. Both the larger cranes feature
a new ergonomic cab design. This improves visibility for the operator by removing the crossmember from the front window, giving a clear view from the floor of the cab to the roof. The front wiper motor has also been lowered, removing another obstruction, and increasing the area covered by the wiper. Other adjustments in the cab
are improved air conditioning, and it's now meant to be easier to adjust the seat and lever positions to suit the individual operator. The G series design includes
a number of environmentally friendly ‘G Mode’ functions, which contribute to lower fuel costs and carbon impacts. As well as an auto idle stop function, these include G Winch, which provides high speed without raising engine speed and G Engine, which improves fuel consumption by at least 10%. HSC Cranes – now a wholly
owned subsidiary of Sumitomo Heavy Industries, which bought out partner Hitachi’s shares in the business – has also upgraded one of its mid-range cranes, with the
Link-Belt’s fifth
generation 218|V. The image below shows it on display at ConExpo '23
third generation of its 275t model: the SCX2800A-3.
This crane is designed using a concept popular in Japan, with a luffing tower – effectively a jib – that allows the crane to work at high and tight radiuses – ideal for constricted city centre job sites. The main boom extends from
15.25m to 91.45m, and the luffing tower can add 21.35m to 61m to overall system length.
EMISSIONS WATCH HSC's new crane focusses on emissions. It features a 270kW Stage V Cummins L9 engine, along with Eco winch mode and auto idle stop to reduce fuel use. Safety has also been a focus of the redesign, with a new approach to positioning handrails and improved access. At the other end of the mid- range scale, Sumitomo Heavy Industries's US subsidiary, Link- Belt Cranes, has been making its own emissions improvements to a long-established model with the launch of the 110USt (100t) 218|V, at ConExpo. The crane traces its design ancestry back over 35 years. As well as its new engine the
crane offers operators a new 12" touchscreen LMI operating system, plus better visibility with

improved sightlines. Ergonomic foot pedals have been moved closer to the cab floor, designed to offer better views of ground level. The new display has an operator
interface with new counterweight sensing for live readout of stacked counterweight, live groundbearing, swing angle indicator, list and trim indicator, engine RPM monitoring, and improved diagnostics. The operator is assisted by
winch-view, back-up, and non-cab side swing-view cameras, with night vision, to enhance jobsite visibility from within the cab. A new optional lighting package also adds LED light on the cabside upper, below the upper and on the front cab for jobsite settings that require additional early morning or evening cover. These developments
demonstrate that the mid-range lattice crawler sector remains dynamic, with continuous innovation addressing evolving industry needs. As these cranes become integral to a broader range of projects, their adaptability, efficiency, and environmental considerations will play pivotal roles in shaping the future of this vital segment within the dynamic crane industry.
