Claim:
A compaction control apparatus for a waste compactor having a waste chamber with a front and back, a hydraulic ram powered by an electric motor, a platen retracted and extended by said ram, a loading door mounted for vertical sliding movement and an unloading opening, and a chamber door on the front of the chamber, the compaction control apparatus comprising: an electromagnetic interlock and sensor switch arranged to interlock the loading door and the chamber door; an off/on/start switch; an interlock solenoid connected to the electromagnetic interlock; at least one gas spring configured with the loading door to apply an upward force sufficient to raise the loading door to its uppermost position; and a plurality of relays interconnected to prevent hazardous baler operations including undesired ram extension or retraction when either of the chamber door or loading door is sensed by the electromagnetic interlock and sensor switch to be improperly positioned for such operation.
