    Before starting the engine, check fuel, hydraulic oil, lubricant, and coolant levels. Inspect all hydraulic cylinders and lines for leaks, and ensure bolts and connections, especially on the boom and undercarriage, are tight. Lastly, scan the worksite to make sure the area is clear of obstacles and safe for operation.

    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.

    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.
