Rubble Master presents the mobile impact crusher RM 120X hybrid with dual drive. The machine operates either on diesel or on 400 V electrical connection. Switching from one mode to the other takes just a few minutes on site. The hybrid equipment is primarily aimed at urban recycling sites with access to the electrical grid.
The RM 120X hybrid develops a power of 170 kW in diesel version. In electric mode, the machine uses a 160 kW motor powered by a standard three-phase connection. Processing capacity reaches up to 250 tonnes per hour for demolition concrete, according to the manufacturer's specifications. The operating weight is 32 tonnes, transport on standard platform possible.
The Austrian manufacturer is betting on energy flexibility. On sites equipped with electrical power, the operator completely eliminates local emissions and reduces operating costs. In the absence of a network, the diesel unit ensures complete autonomy. This dual option meets the requirements of low-emission urban areas while maintaining the mobility needed for remote sites.
For recycling companies, the economic calculation depends on the utilization rate in electric mode. At 2,000 annual operating hours on grid, fuel savings can reach 35,000 liters of diesel. At 1.50 euros per liter, this represents 52,500 euros per year. The additional cost of dual drive is thus amortized in 2 to 3 years depending on usage. Municipal sites with permanent electrical infrastructure benefit most from this technology.
The RM 120X hybrid is part of Rubble Master's progressive electrification strategy. The manufacturer already offers the RM V550e as the first 100% electric jaw crusher. The hybrid version of the impact crusher now expands the range for operators who cannot yet rely solely on the grid. Mobile crushing technology is thus evolving towards mixed energy solutions, adapted to the real constraints of construction sites.
First deliveries of the RM 120X hybrid are scheduled for the second quarter of 2024. The list price has not yet been announced, but an additional cost of 15 to 20% compared to the standard diesel model is likely. For companies subject to urban emission restrictions or public tenders favoring low-carbon solutions, this hybrid machine for on-site recycling represents a concrete alternative to conventional diesel crushers.
