CAT CAT323

The CAT323GC is a 22.5-ton mid-sized hydraulic excavator from Caterpillar, emphasizing high fuel efficiency, low operating costs, and reliable performance. It is suitable for various mid-sized construction scenarios, including earthmoving, foundation work, and road construction, and is particularly ideal for users who prioritize both economy and durability. The machine's operating weight is 22,500 kg, maximum digging depth is 6,730 mm, maximum digging height is 9,450 mm, ground clearance is 470 mm, and climbing ability is 35°. Power System: Equipped with a Cat C4.4 engine, net power is 128.5 kW (ISO 9249), can use up to B20 biodiesel, and meets China's non-road National IV emission standards. Working Equipment: Bucket capacity 1.30 m³, bucket digging force 140 kN, stick digging force 107 kN, maximum traction force 205 kN. Travel and Slewing: Maximum travel speed 5.7 km/h, slewing speed 11.25 r/min, maximum slewing torque... 82kN·m The machine features a new electro-hydraulic main valve and pump, intelligent mode, and high-efficiency cooling fan. Combined with a positive flow control pump, it automatically adjusts flow rate to reduce energy loss. Equipped with intelligent power mode, it automatically matches engine and hydraulic power according to digging conditions, resulting in shorter cycle times under medium and low loads, achieving "low fuel consumption and high output" in earthmoving, foundation excavation, and other operations. Swing torque is increased by approximately 10%, and a rear camera improves operator visibility, allowing for more flexible and precise swinging operations in confined spaces. The Advansys™ bucket teeth enhance soil penetration and can be replaced without special tools, reducing downtime for parts replacement. The equipment can operate stably at altitudes of 3000m and temperatures ranging from 52℃ to -18℃. Dual fuel filtration and sealed track pin bushings effectively extend the service life of the chassis and engine. The cab features an adjustable, spacious seat, automatic temperature control, and low-vibration mounting base. It also provides USB ports and Bluetooth connectivity, significantly reducing operator fatigue. It supports starting the engine via button, Bluetooth key card, or operator ID. The 8-inch touchscreen monitor allows for intuitive viewing of equipment data and access to operation tutorials via QR code. The automatic stop function of the hydraulic hammer also protects the machine from damage caused by air impacts.
