22 m Long Reach Boom for 30 Ton Excavators

Thirty ton carriers are the practical minimum for a 22 m arm. The extra weight of the machine keeps the boom stable at 21.2 m of reach and lets us hang a 0.9 m³ bucket without slowing the cycle to the point where the operator loses patience.

Typical work is river dredging, dock basin cleaning and large pond desilting where a dredger is too expensive to mobilise.
