New Dugless 903: does the work of a 20-strong team in places they can’t reach

The Minprovise Dugless 903 mini loader cleans up underneath conveyor systems, without the need for shutting them down.

The Minprovise Dugless 903 mini loader cleans up underneath conveyor systems, without the need for shutting them down.

Minprovise designed and manufactured the first Dugless 900 mini loader in Australia more than 10 years ago, winning awards for design and innovation.

Safely remote controlled from up to 50m away, the machine eliminates manual handling and can clean up large volumes of spilt material in a fraction of the time. The Dugless 900 has evolved into the Dugless 903, a new generation that features a 3D printed airbox with an enhanced air intake system that delivers more uptime between air filter changes. 

Dust is a major concern for any mining operation, especially in dry and windy areas, so it plays a significant factor in the life of any mining machine.

The Dugless 903 includes a multi-cyclone block that Minprovise managed to fit into a 56-centimetre-tall footprint.

“We’ve been able to get a multi-cyclone block into a very, very small space,” Minprovise general manager Tony Sutton said. “Everything has to be compact. There’s nothing off the shelf you can buy that’s able to achieve what the Dugless 903 does.”

The upgraded Dugless 903 uses vortex cyclones that provide an enhanced level of particle extraction. 

“We could clearly see that the cyclone system pulled dust particles out much more effectively,” Sutton said. 

“You can expect to be around 14 per cent more efficient every day because of less filter change outs. That translates into a significant amount of time and money savings.”

The Dugless 903 also features an air blowback system that expels the ingress of water from the machine after it’s washed. Whether cleaning underneath conveyor systems on dry 

and dusty mine sites or sludgy spillage on project sites and even the odd chicken coup, Sutton said the Dugless 903 has a significant advantage of reaching places

that conventional front-end loaders simply can’t get to, and neither can people. 

“The major advantage of the Dugless, of course, is that you can clean or retrieve spillage while the conveyor is still running, so no shutdown needed for any clean up. And then it’s a spray with the hose, a quick and easy check of filters and it’s ready for action again,” he said.
