حفارة صغيرة مستعملة من نوع كاتربيلر CAT302 مجنزرة هيدروليكية سعة 2 طن للبيع

The Cat 302 CR is powered by a C1.1 engine, boasting a net power of 14.3 kW (ISO standard). Through the precise combination of intelligent features including automatic idle, engine auto-shutdown, and a variable displacement piston pump, along with its load-sensing hydraulic system, it can remarkably cut down on fuel consumption—achieving a medium working condition fuel usage of 0.84 gal/hr (approximately 3.18 L/hr). Its main system can reach a maximum flow of 66 l/min at 2400 rpm, and the advanced load-sensing hydraulic system maintains 245 bar working pressure for equipment and travel operations, achieving an excellent balance between power and efficiency. This, paired with 19.6 kN bucket digging force and adjustable control response, provides the precise control required for various narrow-space excavation operations such as urban construction and indoor renovation.
