Improved transport for Kobelco Construction Machinery’s demolition boom

The challenge of transporting the front-end equipment of high-reach demolition-spec excavators has been a key driver in the development of Kobelco Construction Machinery’s latest models, the 40tonne SK400D and 55tonne SK550D. Both offer working heights of 25m and 28m respectively from a three-piece boom.

Kobelco’s latest demolition boom uses a redesigned intermediate section to reduce its transport height.
The challenge of transporting the front-end equipment of high-reach demolition-spec excavators has been a key driver in the development of 2200 Kobelco Construction Machinery’s latest models, the 40tonne SK400D and 55tonne SK550D. Both offer working heights of 25m and 28m respectively from a three-piece boom.


It is the intermediate boom section that has undergone a redesign, which now benefits from revised hydraulic cylinder positioning. By overlapping the cylinders in a X-pattern, engineers have found a way to fold the boom more tightly than before. This also combines with a much shorter intermediate boom piece, and the resulting transport height falls below two metres.

The firm said that this reduced overall height of the folded boom avoids the need for a specialist low-deck trailer system when getting the machines ready for transport.

    Getting the human-machine interface for equipment automation right is a lot trickier than expected. David Arminas reports from the CECE conference in Rome For many contractors, digitisation is key for improving on-site operational efficiency. But it may be time to take stock of progress and examine what does and doesn’t work. That is not to say that the anchors should be thrown out to halt development. Far from it. In the past eight months, the CECE - Committee for European Construction Equipment – led

    The latest technology continues to improve the quality of concrete paving while contractors are also benefiting from more adaptable equipment - Mike Woof reports For many concrete paving applications, versatility is required rather than a high production rate. Leading paver manufacturers such as GOMACO, Power Curbers, Terex and Wirtgen all offer high mobility machines that can be adjusted to cope with an array of tasks. For a contractor, the advantage of these smaller pavers is that they can be configured q
