Abstract

Systems and methods for a vacuum excavator to prevent to formation of blockages know as spoil bridges are provided. The vacuum excavator includes a high vacuum blower that is coupled through a multi-stage airflow system that has a debris tank to which an excavation hose is coupled. A knuckle boom having two arm segments includes actuators to angularly position the arm segments, and hose roller assemblies that carry the excavation hose. The systems and methods control the angular position of the arm segments to control the flow curvature of the excavation hose from an excavation site to the debris tank in order to eliminate or reduce the occurrences of spoil bridges therein.

Abstract

A motion-transmitting unit including a reciprocating engine having at least one piston operable for reciprocating motion during operation of the reciprocating engine, and a crankshaft interconnected with the at least one piston to rotate in response to the reciprocating motion of the at least one piston, the crankshaft having a first end and a second end opposite the first end. The motion-transmitting unit further includes a first drive shaft interconnected with the first end of the crankshaft to rotate in response to rotation of the crankshaft and a second drive shaft interconnected with the second end of the crankshaft to rotate in response to rotation of the crankshaft.
