Our Biggest Mobile Impactor
Designed For Those Who Must Keep Crushing
The RM 120X mobile impact crusher delivers 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. Best of all, it comes with a 5-year / 5,000-hour limited warranty on all main structural components.
Fast Crusher Adjustment
Our proven single impact wall has three crushing stages, allowing for fast and simple crusher adjustment with only one setting.
High Reduction Ratio
Adjustable rotor speeds, baffled impact plates, and a proven proprietary impact crusher design for achieving a high throughput capacity.
RM Release System
Keep crushing longer by resolving blockages with the touch of a button on your radio remote control.
Asymmetric hopper
Single-piece feed hopper. The asymmetric design aligns slabs before reaching the inlet and reduces bridging.
Pre-screen grizzly (standard)
Bypass fines or discharge fines through an optional side discharge conveyor.
Asymmetric hopper
Single-piece feed hopper. The asymmetric design aligns slabs before reaching the inlet and reduces bridging.
Patented RM Active Grid
The RM Active Grid is an aggressive self-cleaning pre-screen to bypass fines to the main conveyor or to discharge an non-spec material on the side through an optional side-discharge conveyor.
Vibrating Pan Feeder with 25% More Capacity
Hopper wing plates increase hopper capacity and facilitate feeding with large buckets.
Pre-Screen with 2nd Mesh Screen Deck
The RM Active Pre-Screen is an independently driven aggressive pre-screen to bypass fines to the main conveyor or to discharge a spec material on the side through an optional side-discharge conveyor.
Operate with the Touch of a Button
The RM 120X mobile impactor is built to make the most burdensome parts of crushing easy. Its modern information display, performance indicator, and total remote-controlled operation help you get the job done effortlessly. RM XSMART telemetry gives you more insights and clarity about your operation's efficiency, documents performance data, and enables you to troubleshoot issues faster.
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 so that they can maximize production and improve their feeding skills.
Track & CrushX
You are in a pinch if you don't have a conveyor and wheel loader on-site. 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 impact crusher regulates the feed speed according to the crusher load to maximize production and reduce the risk of stalling your crusher.
RM XSMART Telemetry Provides More Intelligence About Your Operation
Access machine telemetry and track tonnages conveniently on your cell phone or computer (optional belt scales).
Your safety is important to us.
This is why we keep your feet on the ground.
Climbing ladders with power tools and heavy parts is a safety hazard. All RUBBLE MASTER mobile impactors are fully ground serviceable, which makes light and safe work out of your daily maintenance.
Operating Position
Closed-circuit setup to crush & screen in a single pass.
Hydraulic folding and swiveling return conveyor minimizes your setup time and labor costs.
Transport Position
Return conveyor is folded for transport. Optional hopper wing plates are broken down for transport.
Hydraulic folding and swiveling return conveyor minimizes your setup time and labor costs.
Service Position
The screen attachment and return conveyor can be lowered to the ground for changing screen media or to dedatch the screen from the crusher.
Hydraulic folding and swiveling return conveyor reduces your setup time and labor costs.
Produce a Cleaner End-Product. Automatically.
The optional wind sifter uses an adjustable air stream to segregate lightweight debris, such as roots and fabrics. Without the wind sifter, you must manually pick contaminants and interrupt your operation more often to clean your screen deck. Improve your bottom line with aggregates people wait in line to buy and less labor involved.
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.
Save Up to 25% on Fuel
Our diesel-electric direct drive burns less fuel compared to traditional diesel-hydraulic tracked impactors.
Works Well in Extreme Temperatures
No heating up of hydraulics in winter and no overheating in summer.
Cut Hydraulic Fluid Costs
Our small hydraulic system is used for auxiliary functions only. Say goodbye to bursting hoses, leaks, and DEP/MOE citations.
Go 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 Detach Screen Attachment
You can break down the machine and move the bare crusher if required. The screen and return conveyor are entirely removed from the crusher.
15 Minutes From Trailer to Crushing
A single operator can get the crusher ready without the need of special hand tools.
Single move
Unlike other mobile impactors in this class, the RM 120X can be moved with the screen attached, saving valuable setup and breakdown time.

Operating a RUBBLE MASTER
is just…awesome.
Don’t just take our word for it.
"RUBBLE MASTER's design is highly efficient, to the point where other brands have attempted to copy it. The efficiency of RUBBLE MASTER is unparalleled in the industry. Additionally, the mobility is a crucial feature."
Nathan Henrich, Flatrate, United States
"If we couldn't crush this material on-site, this job alone would've created over 300,000 tons of excess material "
Eric Bruno, Midwest Crushing and Recycling, United States
