The crusher box features a 3-stage single-apron impact wall for fast and easy adjustment of your closed side setting.

5 Year Warranty

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.

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.

30% Less

Save Up to 30% in Fuel

Our diesel-electric direct drive burns less fuel compared to traditional diesel-hydraulic tracked impactors.

Extreme temperatures

Works Well in Extreme Temperatures

No heating up of hydraulics in winter and no overheating in summer.

Save big on hydraulic fluids

Our small hydraulic system is used for auxiliary functions only. Say goodbye to bursting hoses, leaks, and DEP 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 move

Precision Movements

The refined controls allow for exact maneouvers on the job and while loading.

15 minute setup time

15 Minutes From Trailer to Crushing

A single operator can get the crusher ready without the need of special hand tools.

Single float

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.

"One thing that's impressive. You call any of these guys. They always pick up the phone. They might not have an answer but you get an anwer within hours and not days."

Nathan Henrich, Flatrate Inc.

 

"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
