Product Summary
The HD 500 Mining Digger is a class-leading 52-metric-ton hydraulic excavator built for sustained high-output mining and heavy construction. Powered by a EU Stage V / EPA Tier 4 Final compliant Cummins QSM15 diesel engine delivering 350 kW (469 HP) net power, it combines brute digging force with advanced fuel management. A reinforced box-section undercarriage and 1.8m triple-grouser track shoes ensure superior stability in fractured rock. Each unit comes with a 1-Year Global Warranty and a comprehensive initial spare parts kit, ready for container or RoRo shipment from our centralized export hub.
Why Choose This Machinery
Compared to standard 45-ton class excavators, the HD 500 delivers 18% higher breakout force (312 kN) while consuming up to 9% less fuel via intelligent auto-idle and variable displacement axial piston pumps. The heavy-duty bogie undercarriage with sealed and lubricated track chain extends undercarriage life by 2,500 hours in abrasive conditions. Our direct-to-exporter pricing and consolidated sea freight (40' OT or flat rack, or RoRo) reduce landed costs by 12-15% against major brands. Genuine wear parts (bucket teeth, track pads, hydraulic filters) are stocked in our regional warehouses for 48-hour dispatch.
Powertrain & Structural Overview
The heart of the HD 500 is its Cummins QSM15 heavy-duty diesel, featuring selective catalytic reduction (SCR) and a diesel particulate filter (DPF) for global emissions compliance. Cooling is managed by a dual-plane fin-and-tube radiator with automatic reversing fan, preventing clogging in dusty mines. The main hydraulic system operates at 34.3 MPa (4,980 psi), feeding two independent variable-displacement pumps with a total oil flow of 2 x 350 L/min. Boom and arm cylinders are induction-hardened chrome-plated steel with sacrificial zinc anodes. The cab is FOPS/ROPS certified, with a 7' high-resolution monitor displaying real-time payload, fuel consumption, and maintenance intervals.
Technical Specifications
Below is the primary data for the HD 500 Mining Digger. All parameters are tested under ISO 9249 and SAE J1349 standards.
Heavy-Duty Application Scenarios
Hard Rock Quarrying
Equipped with a 4.2 m³ heavy-duty rock bucket and advance wear-resistant AR400 liner, the HD 500 loads shot rock, granite, and basalt efficiently. The heavy-duty lower frame and rock ejection kit reduce belt and undercarriage damage.
Large Scale Earthmoving
For overburden removal and site development, pair the digger with a 50-70 ton dump truck. The high arm crowd force and 6.1m maximum digging depth allow 3-pass loading of 30m³ trucks, achieving cycle times under 22 seconds.
Mountain & Highway Construction
With optional long reach arm (8.2m) and modified counterweight (8.5t), the HD 500 handles slope protection, drainage trenching, and bench excavation in mountainous terrains, while maintaining 35° gradeability.
Equipment Q&A
Q1: What is the current FOB or CIF export price for the HD 500 mining digger?
Our base FOB (major Chinese port) price for a standard HD 500 is USD 189,500 including one set of heavy-duty bucket, 500-hour initial spare parts kit, and operation manual. CIF/CIP to global main ports (Houston, Rotterdam, Durban, Chittagong, Melbourne) is available upon request with real-time freight quotes. Volume orders (≥ 3 units) receive a 4% discount.
Q2: What is the typical lead time for manufacturing and shipping?
Standard manufacturing lead time is 25-35 working days after deposit confirmation. Container shipping (knocked-down cabin and counterweight) takes 30-45 days; RoRo vessel shipping (fully assembled) takes 35-50 days, depending on destination. Express courier for documents: 3-5 days.
Q3: How does your global warranty and parts support work?
We provide a 1-year or 2,000 operational hour warranty (whichever occurs first) covering structural defects, hydraulic system, powertrain, and electronics. A 'wearing parts package' (teeth, filters, cutting edges, track pads) is available at 15% below list price for first-time buyers. We ship emergency parts via DHL/FedEx within 24 hours of order confirmation.
Q4: Can the mining digger be customized for specific emission standards?
Yes. Standard units meet EU Stage V and US EPA Tier 4 Final. For markets with less stringent requirements (e.g., many African, CIS, and Southeast Asian countries), we can supply Stage IIIA / Tier 3 equivalent engines (Cummins QSM11 or Weichai WP12) with mechanical fuel injection, reducing upfront cost by approximately 8-10%.
Q5: Does the HD 500 come with operator training and documentation?
Each machine includes a complete set of English-language technical manuals (operation, maintenance, parts catalog) and a digital training video on USB. On-site training can be arranged for fleet orders (≥ 5 units) at cost-plus basis. We also provide free remote technical support via WhatsApp/WeChat/Skype for the first 6 months.
