In this era of diverse excavator options, we have conducted specialized improvements and designs based on extensive research and customer feedback. Addressing the challenges faced by excavators in high-temperature environments, we have developed the 50-ton crawler excavator ZT550-9 after numerous tests and comparisons. Equipped with a Cummins QSM11 engine rated at 298kw, our hydraulic system utilizes a K5V230 main pump and comes with a Korean-imported main control valve MO400EX. The reinforced boom and stick are paired with a 3.2 cubic meter rock bucket, and an optional 200-type breaker hammer is available. The increased counterweight enhances the stability of the excavator during excavation and crushing operations. The specialized cab for mining is dustproof, soundproof, and offers excellent airtightness. The anti-vibration suspended seat allows for height adjustment based on body weight. The ZT550-9 is our flagship model, renowned as the king of mountain excavation. Guided by our business philosophy of "Innovation Drives Development, Quality Ensures Survival," our company remains committed to perseverance. Staying true to our original aspirations, we forge ahead, ensuring that our customers can purchase with comfort and use with confidence.
