Cat excavators are well known in industry for their excellent performance and durability, especially in hard rock operations.When you consider buying a Cat excavator for hard rock projects, the price will vary according to the specific model, configuration and location.For example, the Cat320DL excavator, equipped with an efficient break hammer, applies to all types of hard stone excavators at market prices ranging from RMB 1.5 million to RMB 2 million, but the actual purchase costs require that local distributors be consulted for the latest offers.The Cat excavator series has a variety of types, ranging from compact to large-scale coverage, and the efficiency and cost-effectiveness of each piece of equipment in a hard rock setting.The selection of the Cat excavator not only valued its excellent performance under hard rock construction, but also ensured a return on long-term investment through its excellent after-sales services and technical support.Additional operating costs, including fuel consumption, maintenance and possible replacement of spare parts, would also need to be taken into account in order to accurately estimate the specific costs of hard stones for the Cat excavator.It is therefore recommended that clients have a detailed understanding of the technical parameters of different models of excavators and the cost analysis of their use prior to their selection in order to make the most cost-effective decision-making.In summary, there are no fixed answers to the question “How much Cat diggers beat hard stones”, and the key is to select the most suitable type of machine on the basis of actual demand and budget, taking into account geographical factors, market conditions and comprehensive considerations such as after-sales services in order to arrive at the final price formula.Please follow up on Caterpillar's official information or authorize dealers to obtain the most up-to-date and accurate product prices and service details.
