HYDROEX EQUIPMENT

Hydro excavation is the innovative process of removing soil with pressurized water, and then using a vacuum air conveyance to transfer the soil to a debris tank. This non-destructive way to excavate soil can quickly uncover buried natural gas, petroleum pipelines, and water mains, while greatly reducing the risk of damage that can result from traditional mechanical digging. Locate utilities with the power of high pressure water and air movement, to safely expose all of the buried utilities at your dig site and continue your project with the peace of mind that you won’t be left with an expensive clean up bill or injured workers. Dawson Infrastructure Solutions sells, rents and services a comprehensive range of vacuum excavators to safely locate and excavate pipelines, fiber optic lines, cables, and other utilities. We’re a factory authorized distributor for the Ramvac and RamAir lines from Sewer Equipment Company of America.

TRUCK MOUNTED

Tackle your toughest and most challenging jobs while still providing safe, damage-free excavation with truck-mounted hydro excavators. Dawson offers the full line of truck mounted hydro excavators from Ramvac, most notably the industry leading HX-6 Mid Size Hydro Excavator and the bigger HX-12 and HX-15. Rest assured that RAMVAC manufactures the most productive, highest quality, and best value machines available.

The world’s first mid-size hydro excavator, the HX-6, combines the productivity of a large hydro excavator with the maneuverability of a single axle 39,000 pound chassis. The HX-6 is designed to work as productively as the large hydro excavation trucks – and in places they can’t. Work in alleyways, off-road, and all of those hard to get to locations while getting fuel economy that puts the bigger machines to shame. The HX-6 makes the perfect solution for municipalities, utility companies, and hydro excavation contractors. This model is also available with a RamAir air excavation system for when you can’t risk adding water to the problem area.

With larger capacity and great features, the HX-12 and HX-15 bring all of the great Ramvac advantages to you in a larger capacity hydro excavator. The HX-12 and HX-15 feature a 12-yard or 15-yard debris tank respectively for when you can’t leave a big job to unload the material. These models features the industry’s only temperature controlled environmental chamber and a directional discharge system so you can off load your debris back into the excavation site when you are done – without the mess of dumping your tank.

Ramvac understands that operators need a truck that can be repaired in the field quickly with parts that are locally available. The trucks in the HX series are made with easily understood electrical systems and do not rely on complex digital systems. These models are also available with a RamAir air excavation system for when you can’t risk adding water to the problem area.
