حفارة مجنزرة Caterpillar 336D2

The Caterpillar 336D2L is a large excavator with powerful performance, a well-designed design, and high durability. Here's a detailed introduction:
Engine Performance
Powerful: Equipped with a Cat® C9 ACERT™ engine rated at 209 kW (ISO 14396 standard), it provides ample power for excavating tasks such as hard rock and heavy earthwork.
Emission Standards and Environmental Protection: This engine meets US EPA Tier 3, EU Stage IIIA, and China Off-Highway Stage III equivalent emission standards, providing excellent environmental performance.
Energy-Efficient and Reliable: The engine incorporates rugged components and precision manufacturing to ensure reliable and efficient operation. Furthermore, the automatic engine speed control function activates under no-load or light-load conditions, reducing engine speed and fuel consumption.
Hydraulic System
Suitable Flow and Pressure: The main pump's maximum flow rate reaches 281.0 L/min, ensuring quick response and efficient digging during excavation. The maximum pilot system pressure is 4000.0 kPa, providing strong support for precise operation. Regeneration Circuits: Boom and arm regeneration circuits save energy, improve efficiency, shorten cycle times, and reduce pressure loss.
Versatility: Independent pilot pumps provide smooth and precise control of the front linkage, swing, and travel operations. The control circuits can be used to operate a variety of medium- and high-pressure implements, such as hydraulic shears and grab buckets, enhancing the excavator's versatility.
Performance
Adjustable Bucket Capacity: Standard bucket capacities range from 1.88 to 2.41 m³, allowing for adjustments based on specific operational needs.
Extreme Digging Depth and Height: Maximum digging depth reaches 8,210 mm, maximum digging height reaches 10,730 mm, and maximum vertical digging depth reaches 6,290 mm, meeting the demands of large-scale construction operations.
Excellent Travel and Swing Performance: Travel speed is 4.6 km/h, swing speed is 8.98 rpm, maximum traction force is 300 kN, and gradeability reaches 70%, enabling stable operation in complex terrain. Operator Comfort
Comfortable Cab: The cab shell is secured to the frame with viscous rubber mounts, reducing vibration and noise. Thick steel tubing around the bottom perimeter enhances the cab's fatigue and vibration resistance. The suspension seat is multi-adjustable to accommodate operators of all sizes.
Easy Operation: The pilot-operated joystick controls are designed for low effort and maintain a natural wrist and arm posture, reducing fatigue. The operator can also adjust the left and right joystick consoles to suit their preferences.
Effective Climate Control: A pressurized cab with forced filtered ventilation is standard. A switch on the left console allows for selection between fresh and recirculated air to maintain a comfortable cabin temperature.
Easy Maintenance
Easy Serviceability: Routine service and maintenance are quick and easy. Easy-to-change filters and a user-friendly electronic diagnostic system make servicing quick and easy, increasing productivity and reducing maintenance costs.
