Value Added Features


  • Allen-Bradley motor starter.
  • Heavier steel in key structural areas for heavy duty construction: charge box floor and ram face 1/2" steel; ram top, 3/8" steel; sides 1/4" steel plate.
  • TEFC (Totally Enclosed Fan Cooled) motor.
  • Quick release motor mount on the side mounted power unit for easy servicing and maintenance.
  • TRICON Fullness Assurance System. This time shifting device eliminates all but one limit switches. It also produces better compaction rations by making the ram dwell against the trash reducing the "memory" and springback. TRICON offers better cold weather performance and extends the life of the machine.
  • The Pump on Marathon's high performance Side-Mounted Power Unit is secured to a "C" flange TEFC motor with a machined bracket that guarantees coupling alignment. The Limit Switch and all other parts of the power unit are easily accessible for ease-of-maintenance. The Reset Button for the Motor Starter is also located on the outside which eliminates entry into the control box.
  • The RJ-225 features an advanced, simplified control system with 2 button operation. It is key-operated and fully automatic. The heavy duty push button controls are contained in a weatherproof NEMA 13 enclosure. Connected to the power pack with 13' of sealtite, the controls can be located for operator convenience.

Ram Guide System

N/A The packing ram is supported and guided by specially formulated cast iron shoes which ride on replaceable wear strips. This exclusive design protects the charge box floor from the full force of the packing ram, extending its life and dramatically reducing compaction-robbing friction.

Optional Features Available


  • TrashMinder® advanced method for reporting and measuring container usage and fullness; multi-cycle timer; dual controls; ozone odor control system; hoppers and many other options are also available as well as a full line of compaction containers.
  • Chutes can be constructed to meet your specifications and needs. They reduce the risk of pilferage of valuable merchandise or tools by eliminating a person’s ability to hide items in the trash in order to recover them later from the waste receptacle.
