Mentis Africa has supplied positive-grip, pressed-section planks and walkways from its well-known Die-Line range for the Chamber of Mines rescue drilling unit based at Colliery Training College (CTC) a eMalahleni in Mpumalanga. Mentis sales representative, Rene Lombard, explains.
Mentis Africa’s positive-grip, pressed-section planks and walkways from Die-Line range have been supplied to the Chamber of Mines rescue drilling unit based at Colliery Training College (CTC) at eMalahleni in Mpumalanga.
The walkway’s non-slip features, combined with its high strength to weight ratio, made it ideal for the vehicle-mounted drilling unit, says Lombard, external sales representative at Mentis Africa. The walkways and planks have been installed all around the drill vehicle to facilitate easy movement of personnel.
“Its positive serration ensures good traction even in muddy and wet conditions, enhancing the safety and efficiency of people working on the drill during a mine rescue mission,” says Lombard. “Significantly, Mentis Die-Line walkways are lightweight so while being very strong, little extra weight is added to the vehicle.”
The rescue drill is on 24-hour standby to be deployed, with the assistance of CTC staff, in the case of mine accidents. It can drill a 150 mm diameter hole into the underground area where an accident has occurred. This allows the area to be assessed by camera and for food and water to be supplied. It is also capable of drilling a large-diameter hole of 635 mm, down which a capsule can be lowered to bring trapped mineworkers to surface.
“The Mentis Die-Line products are simple to install, requiring no specialised tools and minimal welding or clipping to supports,” Lombard says. “All the necessary bolts, nuts, washers, fishplates, jointing channels, saddle clamps, splice plates and mesh clips are provided.”
Lombard notes that the Mentis Die-Line walkway sections – plants with 2.0 mm thickness and walkways sections with a 2.5 mm thickness, can be provided in either 500 mm or 750 mm widths at a standard length of 2.4 m.
“Where the walkway or panel is subject to a corrosive environment – such as harsh chemicals or saltwater – the mild steel construction can be bitumen-dipped or galvanised,” she says. “This allows these versatile products to be used in a wide variety of applications.”
