Home / Excavators / TB257FR 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 FlowAir conditioning, heater and Bluetooth radio for optimal driver comfort5 LED worklights for optimum illumination of working areaTiltable cabin for easy maintenance and convenient access to hydraulic components and engine buy or rent compare Technical data Huppenkothen added-value equipment Dimensions Lifting load Quick hitch systems Optional equipment General Data ModelTB257FR Fueldiesel CategoryMidi-excavator (5 – 11 t), zero tail excavator Typecabin Boommono boom Designzero tail Side offsetyes hydraulically adjustable track width– Weights and Measures Operative weight6.160 kg Overall width– Overall height2.575 mm Tail swing radius1.180 mm Shipping length (dozer blade in the back)5.905 mm Work performance Excavation depth3.895 mm Discharge height3.890 mm Driving speed4,8 km/h Climbing power30 | 58 Grade | % Boom swing left | right30 | 16 ° Maximum tractive force66,9 kN Digging force bucket36,6 kN Digging force arm23,1 kN Digging force boomN/A Motorization TypeKubota V2607-CR-TE5B Construction type4 cylinder, Common Rail, water cooled Exhaust emissions standardStage V Rated output (ISO 14396)39 kw Torque196 Nm DPFyes SCR (AdBlue)– DOCyes Hydraulic System Hydraulic pumps2 axial piston pumps + 2 gear pumps P1 – TypeAdjustable axial piston pump P1 – Liter60,5 l/min P1 – Pressure240 bar P2 – TypeAdjustable axial piston pump P2 – Liter60,5 l/min P2 – Pressure240 bar P3 – TypeGear pump P3 – Liter9,9 l/min P3 – Pressure206 bar P4 – Type– P4 – Liter– P4 – Pressure– P5 – Type– P5 – Liter– P5 – Pressure– P6 – Type– P6 – Liter– P6 – Pressure– P7 – Type– P7 – Liter– P7 – Pressure– Automatic pressure releaseyes auto-tankyes (return without pressure) Auxiliary circuits1. + 2. + 3. + 4.
