Hitachi Mining Excavators

Hitachi EX Series Mining Excavators: 115 to 837 Tonnes for Open-Pit Mining

Reliability of operation is paramount during mining in continuous 24-hour mode. Hitachi giant excavators are trusted worldwide. Modern EX-7 series models from 120 tonnes operating weight combine long service life with the ability to handle the most demanding mining tasks. The technical excellence of Hitachi excavators, backed by authorised dealer support, significantly raises productivity at any mine or quarry.

Solutions for mining operations

• Electric excavators: environmentally safe machines that eliminate the need for consumables — from fuel and engine oils to replacement oil filters — and help reduce CO2 emissions without any loss of productivity
• Wenco: mine management system provides real-time visualisation of fleet operating status, collects and analyses data on excavator and truck performance, and is used by dispatchers to issue instructions to operators
• Aerial Angle: peripheral monitoring system provides continuous control of the space around the working excavator, detects objects around the machine and delivers warning signals to the operator
• ConSite: service delivers operation reports by email promptly — improving efficiency, reducing downtime and maximising return from your fleet

Global operating experience

Hitachi EX-series mining excavators are the choice of the world's largest mining companies. EX machines operate at copper, molybdenum and gold mines in Australia, Zambia, Chile, Canada, Indonesia and dozens of other countries. Among Hitachi's mining partners is First Quantum Minerals, whose operations span four continents. High-altitude conditions, round-the-clock production cycles and heavy abrasive material — exactly the environment these machines were built for. Armenia's mining industry, with its copper, molybdenum and gold deposits, belongs to exactly this class of operation.

On-site service support

Wayland Armenia is the authorised Hitachi dealer in Armenia. Our engineers travel to customer sites, are cleared for mining zone access and carry full Hitachi diagnostic equipment. Genuine spare parts and consumables are stocked in Yerevan.

Total Cost of Ownership (TCO) and resale value

Professional buyers look beyond the purchase price to the Total Cost of Ownership over a 5–10 year horizon. Hitachi consistently scores well across all key TCO categories:

• Fuel consumption: the HIOS system and ECO mode deliver up to 14% savings — at 2,000 operating hours per year, the difference amounts to tens of thousands of dollars over the machine's life
• Service intervals: up to 500 hours on selected models with a centralised lubrication system — directly reducing maintenance costs and downtime
• Service life: high service life to first major overhaul when the manufacturer's service schedule is followed — one of the best figures in the construction and mining equipment class
• Spare parts: genuine Hitachi components in stock at the authorised dealer in Yerevan — no waiting for delivery, no associated downtime
• Resale value: Hitachi machines hold their value reliably on the secondary market. ZX-series machines with a documented authorised dealer service history sell faster and at higher prices than comparable alternatives — significantly shorter time on market compared to brands with less developed service networks
