TB257FR Compact Excavator

The newest excavator in the FR series, the TB257FR features a side-to-side (STS) offset boom coupled with the tight tail swing for unmatched visibility to the work equipment and enables it to rotate fully with very little overhang.  With an operating weight of 12,930 lb, a bucket breakout force of 10,431 lb and multiple hydraulic auxiliary circuits makes the TB257FR an outstanding attachment platform and perfect for limited space job sites. Its low center of gravity and optimized counterweight placement creates an extremely stable platform with lifting capabilities similar to that of a conventional machine.
