FAQ
What is the typical fuel consumption for a Hitachi EX700 in South Africa?
Fuel consumption for the EX700 can vary significantly based on application, operator technique, and material density. Expect a range of 40-70 litres per hour under typical heavy-duty operation in South African mining or quarrying conditions. Modern engines aim for better efficiency.
Is the Hitachi EX700 suitable for road construction projects?
While capable of large-scale earthmoving for road construction, the EX700's size and capacity are generally overkill for typical road building tasks unless it involves very large cut-and-fill operations or quarrying aggregate for the road base. Smaller excavators are usually more agile and cost-effective for standard roadworks.
What are the main advantages of the EX700 over smaller excavators?
The primary advantages are significantly higher productivity due to larger bucket capacity and digging force, enabling faster cycle times and greater material movement per hour. This makes it ideal for projects where volume and speed are critical, such as large mining operations or dam construction.
How does the availability of parts and service for Hitachi excavators in South Africa compare to other brands?
Hitachi has a well-established dealer network across South Africa, particularly in key mining and industrial hubs. This generally translates to good availability of genuine parts and skilled technicians, which is a critical factor for maintaining uptime and reducing operational costs for heavy equipment.
