Industrial Grade Systems

The RJ-450 features industrial grade electrical and hydraulic systems that are totally UL Listed! This means trouble free operation and top performance year after year. Mark-Costello's side-mounted power unit combines the convenience and ease-of-maintenance that comes with a remote power pack with the space savings and ease-of-installation of an integrated power pack.

Ram Guide System

Ram Guide SystemThe packing ram is supported 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.

All of Mark-Costello's RamJet 225 Series Compactors are Totally UL Listed!


Side-Mount Power Unit

Mark-Costello's Side-Mounted Power Unit, the first in the industry, offers the convenience and ease-of-maintenance of a remote power pack with the space savings of an integrated power pack. This new configuration eliminates ALL electrical components inside the compactor.

The Pump on Mark-Costello'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.

Advanced Control System

The RJ-450 is totally UL listed! The controls are key-operated and fully automatic. The heavy duty push button controls are contained in a weatherproof NEMA 3 enclosure. Connected to the power pack with 13' of sealtite, the controls can be located for operator convenience.
