Hydroexcavating in tight, urban areas can be difficult with a large truck. These heavy units can also leave ruts and other damage if traversing backyards is a must. The Smart-Dig HX-2100 trailer hydroexcavator from LMT solves those issues, offering an easy-to-maneuver and lightweight unit designed for use in difficult to access locations.

“A lot of hydroexcators are looking for smaller units that allow them to get to places their big trucks won’t,” says Rob Southey, the product’s designer. “This unit has a low center of gravity for secure towing and is very compact.”

LMT’s first entry into the trailer hydroexcavator market is powered by a 59 hp Kubota VT2403 diesel engine that drives a 1,300 cfm Tuthill blower and 2,200 psi Udor U.S.A. water blaster. The trailer also has a fully automatic rear-open door with wireless remote control that provides full control of the engine, boom and vacuum operation. The exhaust system was designed with a silencer that absorbs noise, keeping neighborhood disruption to a minimum. An internal stainless steel float ball and seal automatically shuts off the vacuum when the debris tank is full, preventing carryover to the filtration system.

“It offers the power of a full-size hydroexcavator but can be towed with a 3/4-ton pickup,” says Southey. “The target market for a unit like this is onsite system installers, urban municipalities and basically anyone in need of a (smaller) unit instead of a big truck.”

Filtration is provided by the Smart-Dig dropbox, and washable PTFE filters provide full flow at 2,200 cfm. “The blower provides full airflow,” says Southey. “It’s an efficient Tuthill 6015 blower that offers 12 inches Hg.”

An antifreeze winterization system is standard, and an optional diesel-powered water heater is available for colder climates and improved digging performance. The 680-gallon debris tank allows for tipping to 48 degrees, while two side-mounted rotary-molded tanks combine to provide 300 gallons of clean water. A retractable hose reel holds 50 feet of 3/8-inch, high-pressure jetting hose. The optional boom offers fully hydraulic 270-degree rotation, a 25-degree rise and two spotlights for nighttime work. A rear-mounted, 5-inch sight glass provides a visual of the level in the debris tank.

“This unit carries the same principles we used in our HX-4000 truck unit and adds versatility,” says Southey. “It’s easy to use and maintain, and is overall very efficient.” 309/932-3311; www.lmtmfg.com.
