## The Takeuchi TB1140: A Compact Excavator with Unmatched Versatility

The Takeuchi TB1140 is a compact excavator designed to deliver exceptional performance and versatility in a wide range of applications. Its compact size and maneuverability make it ideal for confined spaces and urban environments, while its powerful engine and advanced hydraulic system ensure efficient operation and tackling demanding tasks.

Compact and Agile:



With an overall width of just 78.7 inches, the TB1140 is one of the most compact excavators in its class. This, combined with a short tail swing radius, allows it to navigate narrow passages and work close to obstacles with ease. The independent boom swing and offset boom design further enhance its agility, enabling it to reach over and work in tight corners.

Powerful Performance:



Despite its compact size, the TB1140 is equipped with a powerful 3.3-liter turbocharged diesel engine that delivers 12.8 kW (17.2 hp) of net output. This ensures ample power for digging, lifting, and other demanding applications. The advanced hydraulic system features a variable displacement pump and closed-center load-sensing system, providing smooth and precise control of the excavator's functions.

Operator Comfort and Control:



The TB1140 prioritizes operator comfort and control. The spacious and ergonomically designed cab features a comfortable suspension seat, adjustable controls, and an intuitive instrument panel. The low noise levels and vibration dampening contribute to a fatigue-reducing operating environment. The multi-function LCD monitor displays vital information and allows for easy adjustment of settings.

Versatility and Attachments:



The TB1140's versatility is further enhanced by a wide range of available attachments. These include buckets for digging and excavation, hammers for demolition, and augers for drilling. The hydraulic quick coupler allows for quick and easy attachment changes, maximizing productivity and efficiency.

Durable Construction and Reliability:



The TB1140 is built to withstand the demanding conditions of construction and excavation work. Its sturdy frame and heavy-duty components ensure durability and longevity. The hydraulic system features filters and coolers to protect against contamination and overheating. Regular maintenance and inspections are recommended to ensure optimal performance and reliability throughout the life of the excavator.
