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.

With a clear differentiation between the US and European asphalt paving markets, manufacturers from the latter are now developing machines aimed at the former. The US and European markets for paving machines have developed along very different lines.
