Mecalac has announced a series of major upgrades to its site dumper portfolio including the all new six-tonne 6MDX and nine-tonne 9MDX models, fitted with optional state-of-the-art hydrostatic transmission and the availability of the Roll-Over Protective Structure (ROPS) foldable roll bar, making the cabin optional on these new models.
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.
The addition of hydrostatic transmission improves operator comfort, thanks to smooth and controllable acceleration. Removing the gear stick allows for a more spacious operator environment, while fewer parts mean less maintenance and wear, directly resulting in a lower total cost of ownership.
Both new models will be available with the option of either an integrated cab or all-new ROPS foldable roll bar. 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. 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 the unique isolated MDX cab to minimize vibration and noise, while optional air-conditioning provides outstanding operator well-being in all weather conditions. To ensure a higher level of operator protection in any situation, the certified ROPS/FOPS MDX cab has been additionally designed and tested by Mecalac to withstand impacts while loading the dumper skip.
