FAQ
What is the typical fuel consumption of a Hitachi EX3600-7 in South African mining conditions?
Fuel consumption for the EX3600-7 can vary significantly based on application, operator technique, and material density. However, expect consumption to be in the range of 300-500 litres per hour under heavy load. Hitachi has focused on optimising efficiency in the -7 series to reduce this operational cost.
How does the EX3600-7 compare to its predecessor, the EX3600-6?
The EX3600-7 offers improved fuel efficiency through advanced engine and hydraulic control systems, enhanced operator comfort with a redesigned cab, and increased reliability. While the core digging performance remains similar, the -7 series focuses on lower operating costs and better overall uptime.
What kind of haul trucks is the EX3600-7 designed to load?
The EX3600-7 is optimally matched for loading ultra-class rigid dump trucks with capacities ranging from 150 to 240 tonnes, such as the Hitachi EH3500AC-3, EH4000AC-3, or similar models from other manufacturers. Its bucket capacity allows for efficient 3-5 pass loading.
Is it difficult to transport a machine of this size within South Africa?
Transporting an EX3600-7 is a major logistical undertaking. It requires significant dismantling into multiple components (e.g., boom, stick, counterweight, tracks, main frame) and specialised heavy-haul transport.
