The hydraulic system is the core of an excavator. It converts engine power into hydraulic energy, which drives the boom, arm, bucket, and tracks. Key components include the hydraulic pump, cylinders, motors, control valves, and fluid. This system enables the machine to lift, dig, swing, and travel with precision.

Yes. Our excavators meet CE certification requirements, which ensure compliance with European health, safety, and environmental standards, making them ready for export and operation across the EU market.

Selecting the right excavator for open-pit mining requires a clear understanding of the project's scale and demands. It's essential to match the equipment specifications, such as digging force, structural strength, and hydraulic efficiency, to the specific conditions of the mine site. Factors like ease of maintenance, operator comfort, and the right type of track system also play a major role. In addition, consider the total cost of ownership, which includes not only the initial investment but also fuel efficiency, routine maintenance, and repair costs. Modern features like GPS tracking, remote monitoring, and semi-automation can significantly enhance productivity. Lastly, strong after-sales support and readily available spare parts are crucial when choosing a reliable brand.

Several key elements determine how long an excavator will remain in good working condition. First, the intensity and frequency of use have a direct impact, heavy workloads or continuous operation can wear components out more quickly. Regular maintenance is also essential; timely servicing helps prevent minor issues from becoming serious problems. Operator behavior plays a major role too, well-trained operators who follow proper procedures and safety guidelines are more likely to keep the equipment in better shape over time. Lastly, the working environment matters: harsh conditions like extreme temperatures, high humidity, or dusty terrain can all contribute to faster wear and tear.

When selecting an excavator for orchard use, it’s essential to consider the layout and spacing between trees. Choose a model that fits comfortably within the row width so it can move freely without damaging the plants. The digging depth should meet typical orchard tasks like soil preparation or fertilizer application, usually up to 1.5 meters. Trench width depends on the bucket and can be customized if needed. Also evaluate how much lifting capacity the boom requires for your daily operations. In general, machines between 0.8 and 1.5 tons offer the right balance of size, maneuverability, and power for orchard environments.
