FAQ
What is the typical fuel consumption of a Hitachi ZX870LC-6 in South Africa?
Fuel consumption can vary significantly based on application, operator technique, and material density. However, for heavy-duty work in mining or quarrying, expect consumption to range from 60 to 90 litres per hour. Hitachi's engine and hydraulic optimisation aim to keep this as efficient as possible for its class.
Is the Hitachi ZX870LC-6 suitable for hard rock excavation?
Yes, the ZX870LC-6 is specifically designed for hard rock applications. Its robust construction, high breakout forces, and ability to be fitted with heavy-duty rock buckets and hydraulic hammers make it highly effective in challenging geological conditions common in South African mines and quarries.
What kind of transport is required for an 85-tonne excavator like the ZX870LC-6?
Transporting an 85-tonne excavator requires a specialised heavy-haul lowbed trailer and a powerful prime mover. Due to its size and weight, permits for abnormal loads will be necessary, and route planning must account for bridge capacities, road widths, and potential escorts, which are standard procedures for large equipment moves in South Africa.
What are the main advantages of the 'LC' undercarriage on the ZX870LC-6?
The 'LC' (Long Crawler) undercarriage provides increased stability and a larger footprint, distributing the machine's weight over a greater area. This is particularly beneficial in soft ground conditions, improving flotation and reducing ground pressure, while also enhancing overall stability during heavy lifting and digging operations, crucial for safety and productivity on uneven South African terrain.
