Hydex has adapted robust Rokbak RA30 and RA40 articulated haulers into high-capacity water trucks. As environmental regulations tighten, the need for dust suppression on large sites is growing. A new venture between Hydex and Hills Machinery is using proven ADT technology to deliver effective dust suppression.
At the core is a new water truck range. Rokbak RA30 and RA40 articulated dump trucks (ADTs) are being fitted with high-performance water tanks to be deployed across quarries and infrastructure projects under the Hydex banner.
The rugged RA30 and RA40 are being used as they are able to offer reliability in tough off-road environments. The RA30, with its 276kW engine, now carries a 22,712.5litre (AWT6) water tank, while the 331kW RA40 is matched with a 34,068.71litre (AWT9) tank. Both are equipped with advanced spray and pumping systems for high-performance water distribution. #
The idea came when Hills Machinery, a long-time Rokbak dealer based in North Carolina, saw how contractors were searching for reliable machines that could do more than haul.
Hydex is supporting the rollout through the existing Hills dealership network. Each truck is backed by Hills Machinery’s Uptime Operations service, which includes lifecycle fleet management, real-time equipment monitoring and pre-stocked replacement parts, minimising downtime.
The tanks are engineered to meet demanding performance specs. Water is shot from an American-made Elkhart water cannon to distances of over 64m, while operators can adjust pressure. Multiple spray bars and nozzles, including vertical, side, front bumper and rear dribble, depending on site needs.
A rear-mounted electric hose reel, American-made Berkeley hydraulic water pump and optional suction system for drawing water from lakes or reservoirs round out the functionality.
With their articulated frame, powerful drivetrains and operator-friendly design, Rokbak trucks offer a more robust and stable solution than conventional rigid-frame water trucks – especially when off-road capability is a must.
As Hydex scales production and more water trucks hit the field, this versatile solution might open the door for further adaptations of the Rokbak platform such as fuel and lubrication service units to emergency response and haul support.
