Sheet piling specialist Suttle Projects is looking for work for its remote controlled submersible excavator.
Suttle converted a conventional Kubota mini excavator last year for underwater use. They removed the cab and engine to operate it remotely by hydraulic cables. They reckon it is the only one of its kind in the world.
The Little Mermaid, as they call it, was developed in response to a scour protection project for main contractor Osborne. The river bed needed to be dug out and replaced at the River Colne, near Staines in Surrey. The deep, fast-flowing water and low headroom of a bridge meant that traditional sheet piling techniques were not viable. The headroom was too low for a standard mini excavator to be used on a pontoon with an operator sitting in the cabin. And the water was too deep to over pump the channel or divert flow to create a temporary dry work environment. Therefore, with Osborne’s cooperation, Suttle came up with this solution.
Wacker Neuson’s dual power 803 mini-excavator has won the gold award for innovation in the construction equipment category of the 2015 Intermat innovation awards.
The Wacker Neuson 803 has a regular diesel engine but can also be plugged into a HPU8 electro-hydraulic unit for emissions-free operations with no loss of performance, which can be handy indoors but just watch out for those cables.
The accolade is well enough deserved but I find it slightly strange that a product first presented at Bauma 2013 is still eligible for Intermat’s prizes two years later.
Bradley Demolition owner Paul Johnson is so impressed by the Lehnhoff Variolock Quickcoupler System that he’s starring in a video to make some noise about it.
“I couldn’t believe it when I saw it,” he says. “You can change a work tool – pulveriser, grab, bucket, hammer, shear in just 15 seconds.”
Variolock enables the operator to change any tool including the hydraulic connection at the touch of a button without leaving the cab.
Birmingham-based Coleman & Company has bought a specially-made remote controlled excavator, developed by JCB.
It’s a 21-tonne machine that combines a JCB JS190 upper structure with a JS220LC undercarriage and rubber track pads.
The result, says JCB, is a machine powerful enough to deploy a four-tonne multi-processor attachment without exceeding a gross weight of 25 tonnes.
The new excavator is working 20 hours a day on the redevelopment of Birmingham New Street railway station and is likely to be there for the next nine months.
A new 28-tonne loading shovel has taken over as the prime mover at Suttle’s Swanworth quarry in Dorset.
Suttle went for a Volvo L180H, based on the more than satisfactory performance of its other Volvo machines over the years across its three operating sites. It becomes the largest Volvo shovel in the company’s fleet of seven machines.
Suttle went out to tender for new machinery for Swanworth quarry where it has also invested in a new crushing and screening plant for the site.
