Hitachi Heavy Excavators 50–90t in Armenia

Hitachi Heavy Tracked Excavators: 50–90 Tonne Class

Tracked excavators with an operating weight of 46 to 83 tonnes — equipment for tasks where productivity and service life matter above all else. The three ZAXIS-5A models in this section cover the range from heavy construction to intensive quarry mining: ZX470LC-5A (≈46 t), ZX670LC-5A (≈67 t) and ZX870LC-5A (≈83 t). To purchase a heavy Hitachi excavator in Armenia, contact the authorised dealer — Wayland Armenia.

Model Range: ZX470, ZX670 and ZX870

All three machines are built on the ZAXIS-5A platform and designed for the most demanding conditions, covering different scales of operation:

• Hitachi ZX470LC-5A — approx. 46 tonnes, 345 hp, 3.0 m³ bucket. A powerful excavator for large construction sites, small-to-medium quarries, stripping works and loading of trucks up to 40–50 t. Combines high productivity with relatively lower quarry infrastructure requirements.
• Hitachi ZX670LC-5A — approx. 67 tonnes, 418 hp, 3.8 m³ rock bucket. An excavator for intensive mining: loading of blasted rock, stripping works at medium-scale deposits. Designed for use with trucks from 55–90 t capacity.
• Hitachi ZX870LC-5A — approx. 83 tonnes, 483 hp, 5.0 m³ rock bucket. Flagship of the series for large mining operations. Delivers maximum productivity for ore body extraction and stripping in combination with trucks from 90–130 t capacity.

For the most demanding quarry conditions, all three models are available in the reinforced R configuration — with additional protection of the undercarriage, working equipment and hydraulic system.

How to Choose a Heavy Excavator for a Quarry

Model selection is determined by a combination of site parameters:

• Productivity and mining volume: daily rock-moving requirements determine the minimum bucket size and number of machines needed.
• Truck payload in the loading combination: optimal ratio is 3 to 5 excavator passes per truck cycle. ZX470 suits 40–55 t trucks; ZX670 suits 55–90 t trucks; ZX870 suits 90–130 t trucks.
• Rock category: for blasted rock with high abrasiveness, the R configuration with reinforced components is recommended.
• Operating conditions: site altitude, climate, shift patterns and service accessibility all influence the choice of specification.

Wayland Armenia specialists will help select the optimal model and specification for your specific mining or construction project.

Application in Armenia

Armenia has significant reserves of copper, molybdenum and gold-polymetallic ores, predominantly mined by open-pit methods. Quarry excavators in the 50–90 tonne class are in demand at mining enterprises located in the country's high-altitude regions. The ZAXIS-5A series operates across a wide range of altitudes and climatic conditions, as confirmed by experience at similar sites in mountainous regions worldwide.

In addition to mining, heavy excavators are used on large infrastructure and road construction projects in Armenia: tunnel construction, rock excavation, preparation of industrial-scale construction sites. The ZX470LC-5A is the most versatile machine in this group for such tasks.

Why Hitachi

The HIOS IIIB hydraulic system provides precise arm control during bucket movement, stable lift height when the boom tilts and coordinated hydraulic cylinder operation during arm rotation. This reduces cycle time and improves bucket positioning accuracy during loading — key performance parameters in intensive quarry work.

Cummins engines used in the ZX470–ZX870 series combine high power with compliance with current environmental standards and relatively economical fuel consumption for the class. The cab is designed for multi-hour shifts: good visibility of the working area, an ergonomic control system and an LCD monitor with diagnostics. The undercarriage and working equipment design is built for long-term operation with minimal unplanned downtime.

Hitachi Construction Machinery has extensive experience supplying heavy quarry equipment to the world's largest mining operations — in Australia, Chile, Canada, Indonesia and South Africa. The accumulated operational data is translated into engineering improvements in each successive generation.

Hitachi Service in Armenia

Wayland Armenia is the authorised official dealer of Hitachi Construction Machinery in Armenia. For heavy quarry equipment, the availability of quality after-sales service in-market is especially important:

• Warranty service to manufacturer standards
• Certified engineers trained by Hitachi Construction Machinery
• Original spare parts, oils and filters — from stock in Yerevan, without long lead times
• Field service at your site — critical for quarries with limited transport distance
• Scheduled maintenance and warranty repair
• Post-warranty service and overhaul
• Operator training for heavy quarry equipment
• Minimising unplanned downtime — a priority when servicing mining operations

For quarry equipment, one machine's downtime means direct productivity losses across the entire process chain. Having authorised service and spare parts stock in Armenia is a significant factor when selecting equipment for in-country projects.

Total Cost of Ownership (TCO)

For mining equipment, TCO analysis is especially important: at 5,000–6,000 engine hours per year in two-shift operation, cost differences between machine classes accumulate significantly faster than in construction.

• Fuel consumption: the HIOS system and ECO mode reduce fuel consumption compared to previous generations — specific figures depend on model, load and operating conditions.
• Maintenance: ZAXIS-5A service intervals and the centralised lubrication system reduce planned downtime. At intensive quarry utilisation, this directly affects the machine utilisation rate.
• Original spare parts: stock at the authorised dealer in Yerevan means minimal downtime for unplanned repairs — a key factor for continuously operating sites.
• Service life: with adherence to maintenance schedules, Hitachi ZX-series excavators demonstrate high service life before first overhaul — important for long-term deposit operation planning.
• Residual value: heavy Hitachi quarry equipment with documented service history from an authorised dealer holds its value reliably on the secondary market.

Financing Options

Wayland Armenia offers equipment acquisition through leasing. For mining and construction companies, leasing preserves working capital and spreads capital expenditure over the operating period. Contact us to calculate the terms for your specific project.
