Rich Reach RQ500 Crawler Excavator – 50.5t Mining Machine

Key Features of Rich Reach RQ500 Excavator

1. Powerful & Clean Isuzu Engine

The RQ500 is equipped with an original imported Isuzu 6WG1 diesel engine (296 kW / 1800 rpm). Its advanced “DOC+DPF+EGR+VGS” after-treatment system ensures full compliance with China Stage IV emission regulations — no urea (AdBlue) required, making operation simpler and more economical. The engine control logic has been optimized for lower fuel consumption without sacrificing lugging force.

2. High‑Efficiency Kawasaki Hydraulic System

Featuring a genuine Kawasaki main pump and main valve with positive flow control, the hydraulic system provides ultra-fast response and precise metering. Double-pump confluence delivers a large flow rate (2×360 L/min) and high reliability. The large-diameter main valve core minimizes pressure loss, reduces energy waste, and boosts overall working efficiency — ideal for continuous heavy digging and hard rock operations.

3. Mining‑Grade Reinforced Cab

A skeleton‑reinforced cabin with high‑strength tempered glass comes standard with top and front protective guards, significantly improving operator safety in falling rock environments. The upgraded sealing structure reduces dust ingress, water leakage, and noise, providing a comfortable working environment even in extreme mining sites.

4. Heavy‑Duty Rock Bucket & Multi‑Attachments

Standard equipment includes a 2.6 m³ reinforced rock bucket made of high‑abrasion resistant steel, extending service life in gravel, blasted rock, and overburden stripping. The RQ500 is also ready for hydraulic breaker, pile driver, and other attachments — solving diverse mining and construction challenges and maximizing your return on investment.

5. Intelligent Cooling & Low Noise

The independent hydraulic oil cooling system automatically adjusts fan speed based on oil temperature, keeping the machine thermally stable while reducing parasitic power loss and noise. A anti‑clogging protective net is added for easy daily cleaning and maintenance.

6. Four Working Modes for Versatile Applications

Operators can choose from four power modes via the cab switch: H‑mode (heavy-duty) for digging in rock, S‑mode (economy) for general earthmoving, L‑mode (light/ fine) for precision tasks, and B‑mode (breaker) specifically optimized for hammer attachment work. This flexibility lowers fuel costs and improves productivity across varied job sites.

Frequently Asked Questions (FAQ)

Q1: What is the actual operating weight of the RQ500?

A: The Rich Reach RQ500 has an operating weight of 50,500 kg (50.5 metric tons) including the standard 2.6 m³ rock bucket, full fuel and hydraulic oil, and operator. This provides excellent stability for heavy digging and breaking.

Q2: Does the RQ500 need AdBlue or DEF to meet emission standards?

A: No. The advanced “DOC+DPF+EGR+VGS” after-treatment system allows the RQ500 to comply with China National IV emission standards without diesel exhaust fluid (DEF/AdBlue). This simplifies daily operation, reduces ongoing costs, and eliminates the risk of crystallization in the system.

Q3: What attachments can be used with the RQ500?

A: The RQ500 is ready for multiple attachments including a hydraulic breaker (up to 190 mm breaker class), pile driver, compaction wheel, demolition grapple, and auger. The auxiliary hydraulic circuit is pre-installed as standard. For heavy breaking applications, we recommend using B-mode to optimize hydraulic flow and reduce shock on the boom.

Q4: What is the fuel consumption of the RQ500 in typical mining conditions?

A: Under heavy digging (H-mode), average fuel consumption is around 28–32 L/hour depending on material density and operator skill. In S-mode (economy earthmoving), it can drop below 26 L/hour. The optimized Isuzu engine and hydraulic matching deliver 5–8% better fuel economy compared to previous models.

Q5: How durable is the undercarriage and working equipment?

A: The RQ500 features a reinforced track frame with double grousers, heavy-duty track links, and strengthened boom/arm welding processes (high-stress areas reinforced). The 2.6 m³ rock bucket uses hardox‑style wear plates for severe abrasion resistance – proven in granite and basalt quarries.

Q6: What is the lead time for a new RQ500 excavator?

A: Standard lead time is 20–30 working days after order confirmation and deposit. For urgent requirements, we may have stock machines available. Please contact our sales team for current availability.
