Large hydroexcavation trucks are great for those jobs where there’s plenty of room to work. Many municipalities and contractors are finding that they need the services those rigs provide in smaller, tighter footprints, though. With that in mind, Kaiser Premier developed the TerraVac Xpose800 hydroexcavation trailer to provide big power in a compact footprint.

The TerraVac Xpose800 trailer measures only 21 feet long and 8 feet 6 inches wide, with a height of just 8 feet 8 inches. Equipped with an 800-gallon debris tank and 400-gallon freshwater capacity, the unit has a feature set that makes it suitable for potholing, daylighting or material reclamation. The debris body is lined with a welded stainless-steel floor insert for long-term durability. A bolt-on deflector plate can be quickly replaced during routine maintenance. Conveniently located grease banks and an easily accessible oil drain reduce maintenance time.

“We wanted to offer a solution that was robust enough to operate in tough conditions, but in a compact footprint,” Kaiser Premier marketing director Kenyon Sharp says. “The design and feature set of the TerraVac Xpose800 was dialed in as we received feedback from users in the field.”

Operating power is supplied by a 49 hp diesel engine that enables a crew to easily cut through soil and clay with up to 4,000 psi of pressure at 4.5 gpm. The blower is rated for 960 cfm of suction, capable of 15 inches Hg vacuum with 5 psi positive pressure. A 30-foot suction hose attaches to the 4-inch loading port via a 4- to 3-inch reducer. The digging tool is a 6-foot dig lance, and a 36-inch wash gun is also included.

The controls feature an ignition reset for the water pump to prevent accidental damage or injury. When the engine shuts off, the water pump also shuts off. This safeguard eliminates the risk of the water pump accidentally being engaged when the engine turns on. The dump door is secured via a proven locking bar system similar to Kaiser Premier’s CV Series Hydrovacs. An external door locking design ensures a tight seal without using grabbing claws or internal hydraulics. The dump door also features a 6-inch dumping port for positive pressure offloading.

“Feedback from the field tests is that the TerraVac Xpose800 is easy to operate, easy to unload, and easy to maintain,” Sharp says. “This was exactly our goal in engineering the TerraVac with the operator in mind.” 970-542-1975;
