A 10-tonne Kobelco SK100 excavator was fitted with a long-reach arm and works well.
Richard Lambly of LBM Services in Dargville, New Zealand fitted a 15-metre long-reach arm to a Kobelco SK100 excavator and works really well.
"People said that it couldn’t be done," Lambly says, referring to the cleaning of the Kaihu River with only a 10-tonne digger.
"When we won the tender for the 2013/14 Kaihu River cleaning, one contractor even went so far as to email the council to express his concern at the work being done. Apparently nothing smaller than a 20-tonne machine had ever been used for this sort of work."
To allay fears, the council had Lambly demonstrate his machine before they signed on the dotted line to award him the contract.
"The Kaihu River contract had a window of 12 months to complete. It was done and dusted in six weeks," Lambly says. Standing there beside his excavator, I have a little inward chuckle as the high quality of work has certainly proven naysayers wrong. Indeed, the work can be, and has been, done by a 10-tonne machine.
So despite what some people may think, indeed a 10-tonne machine is more than capable of handling long-reach work. A longer track frame may need to be considered, but it could be achieved without it.
I also should point out that following set traditions does not lead to innovation. This is the first time I’ve seen such a small machine used for this type of work. If Richard Lambly hadn’t decided to try out his theory, then none of us would have thought it possible. He’s just proven that it is.
