RJ-550 Stationary Compactor

[ Specifications | Steel & Operational Options ]

Designed to Handle Heavy Industrial Manufacturing Waste Compaction

Mark-Costello's RamJet RJ-550 is a high capacity, heavy-duty compactor ideal for industrial and commercial applications where large volumes of solid waste are generated. Its rugged construction and large hydraulic power unit allow maximum compaction performance. The RJ-550 features a large 96 1/2" x 60" clear top opening to accommodate oversized crates and cartons.

Built to Last...

A quality built unit, the RJ-550 is solidly reinforced with 4" I-beams throughout. The sturdy ram has a 1/2" face plate. Sides are constructed of 3/16" thick steel supported by 14 vertical angles with 1x4 bar running horizontally on each side of the charge box area for increased rigidity and strength. The tough 1"x8"x6" angle breaker bar easily handles the beating of daily industrial trash.

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!

RJ-550 used in a Transfer Station

Transfer Station...

The RJ-550 is also designed for residential collection vehicles serving transfer station applications for municipalities and private contractors. A conveniently located RJ-550 transfer facility will eliminate the need for unnecessary trips to the landfill by intermediate collection vehicles resulting in fuel, maintenance and labor cost reductions. Compaction into large compaction containers or transfer trailers may also reduce dumping fees.

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.
