Modern dredging technology is not just about mining in water; it is about maximising overall productivity while ensuring high levels of OH&S and ergonomics for all operators and maintenance staff.
The Jaden Kanga Group was called upon recently to design and build a dredger to do exactly this for one longstanding Australian mining company that had been operating with fairly outdated technology.
Immediate efficiencies gained were better stability in the water, much higher efficiency in production and a very ergonomic environment for all employees involved.
The Jaden Kanga Group's Chief Engineer on the project, Mr Grant Barrett, says there were several key technologies which attracted the client to Jaden-Kanga for a solution.
"One of the most significant features we implemented was our patented Jaden S120 ‘cutter disk’ that pulls the dredge into the cut,” said Mr Barrett.
“Others tend to manufacture using a ‘rosebud’ cutter which goes over the top rather than pulling it in during the mining process, hence lowering the return for energy invested.
“We also installed a Five Wire winch system as opposed to a spud dredge which has limited manoeuvrability and is a lot less stable in the water.”
A multitude of advanced engineering specifications were put in place to meet the demanding workload that will be placed on this vehicle, including:
- Electronic Engine CAT 3412E that shows fuel usage, engine load and all diagnostic data.
- On-board 14 Kva Generator (Kubota) powering air conditioning, a computer system, density/flow readouts and a GPS.
- Built to USL Code and under Victorian and Queensland Survey.
- A water jet monitor.
- Full fire protection system.
- 10,000 litre diesel tank.
- Sound proof operators cabin.
The vessel is a 26-metre metre cutter suction dredge powered by an eight hundred horsepower power plant and is engineered to supply five hundred tons of material per hour.
However, it has proved an enormous success delivering substantially more than that specification. This dredge is a replacement for the old unit used at the facility and the owners are more than pleased with the performance of the new vessel.
The client has gained not just increased production, but higher levels of operator comfort with air conditioning and controls that handle easily. The dredger it replaced was an ageing unit and a lot smaller.
The previous dredger genuinely faced the prospect of a ‘face cave in’ – a potentially common incident in this industry which can cause dredgers to be knocked around by the resultant wave. But the new vehicle is highly stable in the water, equipped with better protection and far more accessible for maintenance crews.
The Jaden Kanga Group is an innovative company that has many lines of equipment in its arsenal of products. Not the least is its unique dredge design and manufacturing facility at Burleigh Heads in Queensland, Australia.
The Jaden Kanga Group also designs and manufacturers the famous Jaden winches that are used in many industries including marine, electrical and other major styles of industrial use. Jaden dredges and winches have been supplied to teh industry for more than 29 years. The renowned Kanga mini loader product is also a line that is produced at the Burleigh Heads productions facility.
