Product Summary

The SHT50 Mining Excavator is a Tier 3 / Tier 4 Final compliant, 51.8 metric ton hydraulic excavator designed for high-abrasion mining and large-scale earthmoving. Featuring a robust Cummins QSM15 diesel engine and a negative flow control hydraulic system, it delivers a breakout force of 289 kN and a digging reach of 10.6 meters. Built for the harshest conditions, this model ensures high component durability and easy serviceability for fleet managers.

Why Choose This Machinery

Compared to standard construction excavators, the SHT50 offers a 15% lower fuel consumption per bank cubic meter (BCM) due to its optimized hydraulic flow matching. Key procurement advantages include: 1) Reinforced Underbody: 8 bottom rollers and double-reinforced track frames resist impact from boulders. 2) High ROI: Lower maintenance intervals (500 hrs for swing drive, 1000 hrs for final drives). 3) Supply Chain Ready: Immediate availability of genuine spare parts (pins, bushings, filters) from our global warehouse. 4) Global Logisitics: Export packing and RoRo/Container shipping ready from any major Chinese or UAE port.

Powertrain & Structural Overview

The Cummins QSM15 engine meets global emission standards (EU Stage IIIA / US EPA Tier 3) and is optimized for high-altitude sites up to 4,500 meters. The hydraulic system uses main pumps with a total flow of 2 x 360 L/min, enabling simultaneous swing and boom lift operations without lag. The cab is ISO 12117-2 certified with ROPS/FOPS protection, featuring an air-suspension seat and automatic climate control for operator safety and endurance. The X-frame undercarriage is laser-cut and robot-welded for consistent penetration, with chain links heat-treated to 48-52 HRC hardness.

Technical Specifications

Below is the certified engineering data for the SHT50 Mining Excavator. All parameters follow SAE J/ISO standards.

Heavy-Duty Application Scenarios

Surface & Aggregate Mining

Loading shot rock, blasted limestone, and coal in open-pit mines. The high bucket fill factor and fast cycle time (22 seconds) maximize truck loading efficiency with 40-60 ton haul trucks.

Quarry Overburden Removal

Removing heavy clay and abrasive granite overburden. The heavy-duty track pads and stone ejectors prevent debris buildup, reducing track tensioner failure rates by 30% compared to standard models.

Large-Scale Earthmoving & Infrastructure

Excavating foundation pits for dams, highways, and ports. The high-pressure auxiliary hydraulic circuit allows seamless attachment of large hydraulic hammers or vibratory rippers.

Equipment Q&A

Q1: What is the exact shipping lead time for a trial order of 3 units to West Africa?

A1: Standard lead time for FOB shipment from Shanghai/Tianjin is 20-25 working days after receipt of deposit. For LoLo or RoRo shipping to major West African ports (Tema, Apapa, Abidjan), we coordinate with COSCO and Maersk. Express 10-day delivery is available for an additional logistics premium.

Q2: How does the 1-Year Global Warranty work for parts purchased outside the manufacturer's region?

A2: Our warranty covers the powertrain and main hydraulic components (engine, pump, main valves, final drives) for 2000 operating hours or 12 months. For international claims, we ship replacement parts via DHL Express, and the buyer's local mechanic is reimbursed at standard labor rates. Wear parts (teeth, filters, tracks) are excluded but are heavily discounted in our B2B starter spare parts kit.

Q3: Do you provide operational training if we buy 5+ units?

A3: Yes, for orders exceeding 5 units, we offer a 3-day on-site training program for your master mechanics and operators. The training covers advanced hydraulic diagnostics, the machine's CAN-bus system, and fuel-efficient digging techniques. Alternatively, we provide full digital manuals and video SOPs.

Q4: What emission standard does the SHT50 meet, and is it restricted in the EU?

A4: The SHT50 is available in two configurations: Standard (China IV, equivalent to EU Stage IIIA) for Africa, ME, and SEA markets, and an EU Stage V compliant version with a DPF and SCR system. The EU Stage V version carries a 7% premium but is fully importable into Germany, France, and Poland with CE certifications provided.

Q5: Can you supply a full set of wear parts for 10,000 operating hours immediately with the machine?

A5: Absolutely. We recommend our 10k-Hour Maintenance Package (Bucket teeth, side cutters, track shoes, sprocket rings, filters, and hydraulic oil). This package is packed in a separate 20ft container alongside the machinery. By ordering the package upfront, buyers save 18% on international logistics and avoid customs clearance delays for individual parts later.
