The Caterpillar 345BL hydraulic excavator, introduced in the late 1990s, stands as a testament to Caterpillar's commitment to engineering excellence. Designed for heavy-duty applications, this machine has become a staple in various industries, including construction, mining, and demolition.
Engine and Performance Specifications
At the heart of the 345BL lies the Cat 3176C ATAAC engine, delivering a net flywheel power of 321 horsepower (239 kW). This powertrain enables the excavator to tackle demanding tasks with ease. The machine's maximum travel speed is approximately 2.73 mph (4.4 km/h), allowing for efficient movement across job sites.
Hydraulic System and Operational Capacity
The 345BL is equipped with a hydraulic system that boasts a pump flow capacity of 169 gallons per minute (640 liters per minute) and a system relief valve pressure of 4,980 psi. These specifications ensure robust lifting and digging capabilities. The machine's operating weight varies based on configuration, with a standard setup weighing around 97,000 lbs (44,000 kg) .
Undercarriage and Dimensions
The undercarriage of the 345BL features a track width of 600 mm, providing stability on uneven terrains. The machine's transport dimensions include a length of 14.1 meters, a width of 3.85 meters, and a height of 4.6 meters .
Common Issues and Troubleshooting
While the 345BL is renowned for its durability, operators may encounter certain issues over time. One common problem is slow stick motion, often attributed to internal seal leaks causing pressure loss. Regular inspection of the cylinder's rod and piston seals, along with maintaining proper hydraulic fluid levels and cleanliness, can mitigate this issue .
Another area of concern is the undercarriage. Over time, wear and tear can lead to reduced performance. Regular maintenance, including track tension adjustments and replacing worn components, is essential to prolong the life of the undercarriage.
Maintenance Tips
To ensure the longevity and optimal performance of the 345BL, adhere to the following maintenance practices:
The Caterpillar 345BL excavator remains a reliable and powerful machine for heavy-duty applications. By adhering to recommended maintenance practices and promptly addressing common issues, operators can ensure the machine's longevity and optimal performance on the job site.
