Introduction
The Takeuchi TB135 mini excavator, introduced in the mid-2000s, has established itself as a reliable and efficient machine in the compact excavator market. Designed for versatility and performance, the TB135 is suitable for various applications, including landscaping, utility work, and general construction tasks. Its compact size and robust capabilities make it a valuable asset for both urban and rural job sites.
Engine and Powertrain
At the heart of the TB135 is the Yanmar 3TNV88-QTB engine, a three-cylinder, naturally aspirated diesel engine renowned for its durability and fuel efficiency. This engine delivers a net power output of 27.8 horsepower at 2,300 RPM, with a maximum torque of 79 lb-ft at 1,400 RPM. The engine's design emphasizes low emissions and compliance with environmental standards, making it suitable for various regulatory environments.
Hydraulic System
The TB135 is equipped with a hydraulic system that operates at a relief valve pressure of 3,000 psi, ensuring sufficient force for demanding tasks. The hydraulic pump delivers a flow rate of 19.8 gallons per minute, providing ample capacity for simultaneous operations. The system's design includes variable displacement axial piston pumps combined with gear pumps, optimizing efficiency and responsiveness. Additionally, the auxiliary hydraulic flow is 15.6 gallons per minute, allowing for the operation of various attachments.
Performance and Lifting Capacities
The TB135's performance is characterized by its impressive digging and lifting capabilities. The maximum digging depth reaches 11.2 feet, enabling operators to tackle deep excavation tasks. The machine's lifting capacities vary depending on the configuration:
Undercarriage and Mobility
The TB135 features a rubber crawler undercarriage with a track width of 14 inches, providing stability and minimizing ground disturbance. The machine's ground pressure is approximately 3.9 psi, allowing it to operate on soft or sensitive surfaces without causing significant compaction. The travel speed ranges from 1.5 mph in low gear to 2.9 mph in high gear, offering flexibility for various job site conditions.
Dimensions and Transportability
With a transport length of 16.6 feet, width of 5.4 feet, and height of 8 feet, the TB135 is compact enough to navigate confined spaces while providing ample workspace for operators. Its operating weight is approximately 7,831 lbs, making it manageable for transportation and suitable for urban environments where space is limited.
Maintenance and Operational Considerations
Regular maintenance is crucial to ensure the TB135's longevity and optimal performance. Operators should monitor hydraulic fluid levels, check for leaks, and replace filters as needed. Additionally, keeping the machine clean and inspecting it for wear and tear can prevent potential issues. The TB135's design facilitates ease of maintenance, with accessible components and service points.
Conclusion
The Takeuchi TB135 mini excavator stands out in the compact excavator market for its blend of power, efficiency, and versatility. Its robust hydraulic system, impressive lifting capacities, and compact dimensions make it an excellent choice for a wide range of applications. Whether working in tight urban spaces or on expansive rural sites, the TB135 delivers reliable performance, contributing to increased productivity and reduced operational costs.
