Remote Operation
Vacmasters System 4000 is designed to help utilities and utility contractors reduce costs and increase production by automating the potholing process and cutting time to 7 or 8 minutes in any kind of soil conditions, the manufacturer claims. The vacuum excavation uses the kinetic energy in a high velocity air stream to penetrate, expand and break up soil to expose buried utilities. The process won't damage the road base. The system is installed on a 25,950 GVW (Non-CDL) diesel chassis and features remote operation up to 200 ft away. VACMASTERS; 800/466-7825;
