TB257FR

The Takeuchi mini excavator TB257FR is specifically designed for unrestricted working on very confined construction sites. The patented side-to-side (STS) offset boom makes this zero tail excavator more compact and the best alternative to a short tail excavator. The upperstructure rotates 360° nearly within the width of the track. With a surrounding diameter of just 2870 mm, the TB257FR is also ideal for working in narrow streets where space is confined.

  • 1st hydraulic circuit, with proportional control with 105 l/min High Flow
  • Air conditioning, heater and Bluetooth radio for optimal driver comfort
  • 5 LED worklights for optimum illumination of working area
  • Tiltable cabin for easy maintenance and convenient access to hydraulic components and engine
