Mecalac has announced upgrades to its range of site dumpers, introducing all-new 6t and 9t models fitted with optional hydrostatic transmissions and making an ROPS (Roll-Over Protective Structure) foldable roll bar available on the new models, which make the cabin optional.
The company said that the step follows the global success of its MDX range and the recent launch of its 3.5t model, the 3.5MDX. The new 6t and 9t models are the 6MDX and 9MDX, which will offer the choice of the hydrostatic transmission for improved comfort and safety.
“Widely used across the construction equipment industry, the adoption of hydrostatic transmission replaces mechanical transmission with fixed gear ratios. This ensures easier operations without gear shifting and provides the added benefit of responsive dynamic braking. This makes operation easier and safer for both experienced and new operators, meaning the new hydrostatic 6MDX and 9MDX are perfect for both rental fleets and operators that frequently change their equipment,” said a statement from Mecalac.
The company added that the addition of hydrostatic transmission also guarantees improved operator comfort, thanks to smooth and controllable acceleration. Removing the gear stick allows for a more spacious operator environment, while fewer parts for less maintenance and overall less wear, directly resulting in a lower total cost of ownership. Both 6MDX and 9MDX deliver high torque and traction and are suitable for steep inclines where gear changes can often result in loss of drive, said Mecalac.
Both new models will also be available with the option of either an integrated cab or all-new ROPS foldable roll bar. The ROPS models are easy to transport between job-sites and allow operators to work in low height areas with ease. The structure is easily foldable, thanks to a handle and gas strut, which means folding and unfolding the ROPS is safe and requires minimal manual effort, said Mecalac, adding that because the ROPS roll bar has significantly fewer components than a cab, it is an economical choice, but still offers superior operator protection.
For additional safety and comfort, the 6MDX and 9MDX can be fitted with Mecalac’s isolated MDX cab to minimise vibration and noise, while optional air-conditioning provides operator well-being in all weather conditions. For greater operator protection, the certified ROPS/FOPS MDX cab has been additionally designed and tested by Mecalac to withstand impacts while loading the dumper skip.
