2019 - Roadtec RX700E Cold Milling

About this machine

This Roadtec RX700E is a used cold milling machine — also commonly referred to as a road milling machine or pavement milling machine — offered from Texas, USA, at $350,000. Cold millers are used to remove and recycle asphalt and concrete pavement surfaces, profiling road beds prior to resurfacing or performing full-depth reclamation work. Roadtec is a well-established American manufacturer of road construction and paving equipment, producing machines used extensively by highway contractors, municipalities, and asphalt specialists across the industry.

This 2019 machine is powered by a Caterpillar C18 engine rated at 800 hp to Tier 4F emissions standards. Engine Load Control is included to manage power delivery under varying cutting conditions, and the machine features Automatic Traction Control alongside four steering modes — front, rear, crab, and coordinated — giving operators considerable flexibility when maneuvering in confined or irregular work zones. Propulsion is provided by Direct Hydraulic Planetary Track Drives, and a foot-per-minute meter allows the operator to monitor ground speed relative to production output.

The cutter assembly measures 7 feet 2 inches (86 inches / 2.18 m) in width and is configured as a bolt-on unit driven by a mechanical V-belt drive. The gearbox is a W-50 Fairfield unit fitted with a break-away input shaft for drivetrain protection. The drum itself is a Kennametal Single Hit drum at the same 86-inch width, with 5/8-inch tool spacing. Maximum depth of cut is 14 inches, and the cutter housing is constructed from T-1 steel with chromium-clad wear liners under the Ironclad designation. Powered wrap-around end gates with replaceable wear shoes and sloped front and rear moldboards complete the cutting system. Front and rear water spray bars are fitted with individual flow and pressure control, supported by a hydraulic variable-flow water pump and an automatic on/off spray water system, alongside a high-pressure wash-down system for general cleaning.

Material handling is handled by a 36-inch primary conveyor with an endless heavy-duty belt and a 36-inch secondary conveyor also fitted with an endless belt, both equipped with 3/4-inch tall molded rubber cleats. The secondary conveyor offers a full 120-degree swing capability and is fitted with truck rails to aid accurate loading. Head and tail pulleys on both conveyors are self-cleaning. The machine runs on polyurethane bolt-on replaceable track pads.

The operator environment includes a shock-mounted platform and console, dual full-function control stations on both the left and right sides of the machine, a lighted instrument console with liquid-filled gauges, and ground-level controls for the moldboard, end gates, and elevation. The operator's console is fitted with an umbrella and mounting hardware. Safety provisions include emergency engine shut-down, a cutter disengage function, and an automatic engine shut-down that triggers when the cutter door is opened. A rear back-up camera and a dust extraction system are also fitted. Additional practical equipment includes an air compressor with reservoir and air tools, remote grease fittings arranged in zones, a light package of ten 24-volt lights, two magnetic-base 24 VDC halogen work lights, and six 24 VDC power outlets.

The machine is equipped with the ACE Grade and Slope Automation system with Auto-Cut, which automates front and rear leg elevation using grade and slope sensors, automates rear elevation during cut entry, and is operated via three ACE control panels positionable at the operator station, mid-machine at ground level, or at the rear. The system incorporates a central microcontroller, a five-eye sonic sensor, MOBA brand slope and sonic sensors, and all associated cabling, junction boxes, and plugs. Pre-wiring for an ACE Averaging Ski is also included, with junction boxes and cables run to the corners of the machine. A 24V LED night light package of four lights with mounting hardware and wiring rounds out the options included in the listed price. A one-year factory warranty is noted by the seller.
