We offer a wide range of attachments to meet different construction needs. These most common attachments include: standard buckets for earthmoving, hydraulic breakers for rock or concrete demolition, hydraulic shears for dismantling structures, log grapples for handling timber or pipes, rippers for compacted soil or frozen ground, vibratory compactors for backfilling, augers for drilling and piling, dredging buckets for clearing silt, and quick couplers for fast tool changes. These options make our machines suitable for civil works, mining, municipal maintenance, and forestry.

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.

Hydraulic crawler excavators are built for strength and stability, especially in challenging terrain. Instead of wheels, they rely on wide, heavy-duty tracks that evenly distribute the machine’s weight, allowing for excellent traction and balance on uneven or sloped surfaces. Compared to wheeled models, they deliver superior grip and lifting capacity, making them more effective in rough or muddy ground conditions. Their low center of gravity and well-balanced structure also enhance lifting performance, enabling them to handle heavy loads with greater ease and stability.

These machines are versatile and ideal for municipal infrastructure, road construction, and earthmoving tasks at building sites. Their powerful digging ability and steady movement make them especially suitable for projects requiring smooth, coordinated actions across different job stages.
