Vacuum excavator offers optional hydraulic boom

Reverse-flow hydraulic boom operates with manufacturer’s line of 500-, 800- and 1,200-gal. vacuum excavators to reduce operator fatigue and enhance productivity. The boom rotates 270° and telescopes to a maximum reach of 14 ft. from pivot point. Wireless remote control adjusts height and extension of boom. Operator can choose either manual or hydraulic boom rotation. Auxiliary hydraulic motor also can power other hydraulic tools, eliminating the need for additional compressors at job site. If boom’s 4-in.-diameter hose becomes blocked with rock debris during vacuum process, operator can reverse air flow to blow the clog out of the hose. For large projects, reverse flow can be used to offload vacuum spoils into a holding vessel. For smaller projects, reverse flow can help workers backfill holes easily. Available with 5-ft.-long hose extensions. McLaughlin Group Inc., Greenville, S.C.
