Safety First Design
Safety is the most important part of the RM 120X mobile impact crusher so that you can trust your guys around the machine.
Our biggest mobile impactor designed for those who must keep crushing
The RM 120X impactor delivres a high reduction ratio while being easy to maintain. The 4-bar rotor is driven directly through a 400 HP John Deere diesel engine and can be used in primary and secondary crushing applications. The crusher box features a 3-stage single-apron impact wall for fast and easy adjustment of your closed side setting.
You deserve not only great mobile impactor but also the industry's best support.
The RM 120X mobile impactor comes standard with a 5 year / 5,000 hours limited warranty on all structural main components. Contact your dealer for details.

The RM Release System helps to remove blockages and keeps your crushing
By the press of a button on your radio remote control the release system is activated. The apron is pushed back so that the material can clear the inlet and you keep crushing without leaving your cab.
Built With Operators, For Operators
The RM 120X advanced safety and convenience features are designed to assist you with the most burdensome parts of crushing.
Total Crusher Control
All functions are on your radio remote control.
Operator Assistance
Instant visual response on crushing performance, automated feed control and emergency machine shutoffs.
Easy Troubleshooting
Fault codes with easy to understand on-board resolutions.
Performance IndicatorX
Overfeeding or underfeeding your crusher slows you down. The Performance Indicator visualizes the utilization of the machine and helps operators find the sweet spot of the machine so that they can maximize production and improve their feeding skills.
Track & CrushX
If you don't have a conveyor and wheel loader on-site you are in a pinch. RUBBLE MASTER mobile impactors can be moved while crushing so that you can windrow your material and keep crushing.
Status LightingX
Status lights show the condition of the machine.
- Green - in operation / ready to crush
- Yellow - not ready to be fed or the machine is being moved
- Red - not ready because there is an issue
Load dependent feed speedX
The RM 120X mobile impactor regulated the feed speed according to the crusher load to maximize production and reduce the risk of stalling your crusher.
Access machine telemetry and track tonnages conveniently on your cell phone or computer.
RM XSMART telemetry and fleet management helps you to optimize your processes and make more money. It connects the dots between service, operators, and your dealer to save time and keep your crushing. Belt-scales are optional.
Safety is important to us. This is why we keep your feet on the ground.
Climbing ladders with power tools and heavy wear parts is a safety hazard. All RUBBLE MASTER mobile impactors are fully ground serviceable which makes light & safe work out of your dailies. Plus, you can trust your guys around the machine.
5' x 12' Single Deck Screen
The RM 120X Mobile Impactor comes with a large 2 section 5' x 12' screen attachment for a closed circuit production. Standard is also a spreader plate to distribute material evenly across the screen.
Changes as fast as your job requirements.
Hydraulic folding and swiviling return conveyor reduces your setup time and labor costs.
Closed-circuit setup
One operator can set up the mobile impactor conveniently without the need of any hand tools so that your time from trailer to crushing is as low as 15 minutes.
2-way split
Produce a finished product and an oversize product by swivelling the return conveyor 90°. This maximizes production and minimizes wear.
Service position
The screen deck can be lowered hydraulically to be detched or for maintenance. The generous ground-based access allows for fast screen media changes to minimize downtime.
Move Anywhere, Anytime
Experience the freedom of folding up your machine and going anywhere you want. The RM 120X, like all RUBBLE MASTER mobile impactors, was designed with mobility in mind making it easy to move.
Easy to Mobilize
Can be moved easily from site to site.

Make more money per produced ton with diesel-electric mobile impactors
RUBBLE MASTER has been utilizing diesel-electric drives for its mobile crushers since our beginning in 1991. This well-proven system offers many benefits over conventional diesel-hydraulic drives - most notably its significant lower fuel consumption and surprisingly low noise emissions.
Less Fuel Burn
More efficient drive than conventional diesel-hydraulic crushers.
Works Well in Extreme Temperatures.
No overheating in summer, no heating-up in winter.
Less than 30 gal
Small hydraulic system to operate auxiliary cylinders and tracks.
