Rubble Master will debut its RM 90X and RM 100X mobile impact crushers in North America at CONEXPO-CON/AGG 2026, scheduled for March 3–7 in Las Vegas.
The RM 90X and RM 100X build on the company’s existing RM 90GO! and RM 100GO! platforms. The RM 90X features a 34-inch by 25-inch inlet opening and weighs less than 68,000 pounds. The RM 100X includes a 38-inch by 28-inch inlet opening and weighs less than 79,000 pounds.
Both models incorporate diesel-electric drives and updated control systems under the company’s RM NEXT design approach. A 12-inch display provides setup guidance, troubleshooting tools and service diagnostics. The machines also include a performance indicator, status lighting and radio-controlled operation.
An updated heavy-duty rotor increases rotor inertia by 25% on the RM 90X and 17% on the RM 100X compared with previous models, aimed at improving consistency and reducing wear. The crushers also feature the company’s mechanical release system designed to limit damage from uncrushable materials.
The RM XSMART app allows operators to monitor machine performance and, with optional belt scales, control calibration and reporting functions from the cab.
