ABSTRACT:
A hydraulic compactor system includes a portable container adapted to be transported by a truck and having a chamber for receiving a waste material to be compacted. The container has a self-contained compacting ram actuated by a hydraulic cylinder, and a remote hydraulic power supply unit is connected to the hydraulic cylinder by flexible hydraulic hoses. Each of the hoses is provided with a breakaway hydraulic coupling having two sections connected by tension releasable coupling means with the sections having spring biased valves which are open when the sections are coupled together and automatically close when the sections separate due to a predetermined tension force on the hoses. Each breakaway coupling compensates for increases in hydraulic fluid pressure to prevent separation of the coupling sections when the fluid pressure increases to actuate the hydraulic compacting cylinder.
