Rich Reach RQ75 7.7t crawler excavator with 46.2kW Yanmar engine, 0.28–0.32m³ bucket, load-sensing hydraulics, ideal for municipal, housing & farm projects.
The Rich Reach RQ75 crawler excavator is a powerful and compact machine engineered for small to medium-sized earthmoving projects. With an operating weight of 7,680 kg and a bucket capacity range of 0.28–0.32 m³, the RQ75 delivers superior digging force, fuel efficiency, and operational comfort. Powered by a Yanmar 4TNV98C engine (46.2 kW @ 2200 rpm) meeting China Stage IV emission standards, it features DOC+DPF+EGR aftertreatment technology — no urea required. Whether you work in urban renovation, municipal construction, housing foundations, or farmland irrigation, the RQ75 offers excellent performance and low total cost of ownership.
The RQ75 integrates a Yanmar 4TNV98C diesel engine delivering 46.2 kW of robust power with low noise levels. Advanced DOC+DPF+EGR exhaust aftertreatment ensures full compliance with strict emission regulations without the hassle of AdBlue/urea. This reduces operating costs and simplifies daily maintenance, making it ideal for long-hour operations in residential or sensitive areas.
Equipped with a load-sensing hydraulic system and high-displacement main pump & large-bore main valve, the RQ75 provides fast response times, precise controllability, and outstanding fuel efficiency. The optimized valve core structure reduces pressure loss, delivering smooth, low-impact digging actions and superior grading performance. Max hydraulic flow reaches 156 L/min, working pressure up to 28 MPa, ensuring excellent multifunction coordination and cycle times.
The RQ75 features a reinforced frame-type cabin with increased rigidity and post-style protective design. Standard equipment includes a suspension seat, emergency hammer, fire extinguisher, and upgraded multi-function control panel for fatigue-free operation. The spacious interior and excellent all-around visibility boost operator confidence in tight job sites.
Adaptable to diverse applications, the RQ75 supports quick-change attachments including hydraulic breakers, narrow buckets, rippers, and tilt rotators. The reinforced high-wear-resistant steel bucket features an optimized shape to reduce digging resistance, improving productivity while lowering fuel burn.
Daily checks and servicing are effortless thanks to the three-door rear cover design offering spacious access to engine, filters, and cooling components. Routine maintenance points are grouped conveniently, reducing downtime and maximizing machine availability.
