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.

With proper care, most excavators used in mining can operate between 7,000 and 10,000 hours. Actual lifespan depends on usage intensity, maintenance frequency, and machine quality. Some units may last even longer if handled correctly and serviced regularly.

For trenching in tight or confined areas, compact excavators with a smaller footprint are usually the best fit. Models under 1 ton are particularly suitable for narrow trenching tasks, as they offer the maneuverability needed to operate in limited spaces while still delivering enough digging power. These machines can typically reach depths of around 9 feet, making them a practical solution for small-scale excavation in tight work zones.

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.
