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 30% in 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.
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.
Precision Movements
The refined controls allow for exact maneouvers on the job and while loading.
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.
