Abstract
A side loading refuse collection vehicle having a carriage slidably mounted on a track and pivotally carrying a lift arm assembly including refuse container grabbing and dumping apparatus for grabbing a refuse container, lifting it and dumping it into the body of the vehicle includes a keeper plate secured to the carriage and a detent latch pivotally mounted on the frame for seizing and holding the keeper selectively. The carriage is slidably driven by a hydraulic cylinder assembly to extend and retract the carriage relative to the vehicle, and whenever the hydraulic cylinder assembly is actuated by an operator control switch the latch disengages from the keeper. When the hydraulic cylinder assembly is not actuated, the latch engages and holds the keeper and thereby prevents the lift arm from being flung outwardly in the event of a failure in the hydraulic cylinder assembly system.
