履带式挖掘机 Caterpillar 315DL

The Cat 315D excavator offers the following advantages:
Powerful Performance
Advanced Engine Technology: The Cat® C4.2 engine features ACERT™ Technology, optimizing performance and meeting U.S. EPA Tier 3 and EU Stage IIIA emission standards. ACERT Technology reduces combustion emissions through advanced air and fuel system technology and integrated electronics.
Stable Power Output: The engine is rated at 86 kW, and three-level controls and one-touch command maximize fuel efficiency and reduce sound levels. Heat-resistant aluminum alloy pistons with a short compression height provide increased efficiency and long life.
Efficient Hydraulic System
High Digging Force: 2% higher hydraulic system pressure generates greater lifting, swing torque, and digging force, making it easy to tackle a wide range of construction challenges.
Precise Control: The hydraulic cross-sensing system allows both hydraulic pumps to utilize 100% of the engine's power, boosting productivity with faster implement speeds and quicker, more powerful pivot turns. Auxiliary hydraulics and electrical lines are routed to the boom mount, making hydraulic circuit installation easier. The new compact design utilizes shorter tubes and lines, reducing friction and pressure drop for more efficient power use.

Comfortable and Convenient Operation

Comfortable Cab Environment: The cab is spacious, quiet, and comfortable, pressurized to 50 Pa to reduce dust intrusion. The comfortable seat adjusts to the operator's size and weight, with an optional air suspension seat. Standard air conditioning with automatic climate control adjusts temperature and airflow, and low-effort joystick controls maintain a natural wrist and arm posture, reducing fatigue.

User-Friendly Operator Interface: The LCD monitor displays important operating and performance information in 27 different languages ​​for easy viewing. The travel motors feature an automatic speed select function, allowing the 315D to automatically switch between high and low speeds in a smooth and controlled manner. Rugged and Durable Structure
Reliable Working Attachments: Cat booms and sticks are designed for high performance and long service life. They feature welded box-section construction constructed from multiple high-strength steel plates. The 315D also offers four different stick options for each boom model to meet diverse operating requirements.
Excellent Machine Stability: 6% additional counterweight improves balance and lifting capacity, making the machine more stable during operation.
Easy Maintenance
Easy Daily Maintenance: All routine maintenance points are accessible from ground level, making them easier for service technicians and reducing maintenance effort and costs.
Long Filter Life: The hydraulic oil filter provides improved filtration performance and features an anti-drain valve to keep the oil clean between filter changes. The change interval is 3,000 hours, 50% longer than previous filter design life. Furthermore, the longer filter life can save up to 10% on maintenance component costs.
