Refurbished ABB IRB 8700-550/4.20 Heavy-Duty 6-Axis Robot | 550kg Rated Payload, 4.2m Long Reach for Large Sheet & LFAM 3D Printing

The IRB8700-550/4.20 prioritizes an extended reach to satisfy applications requiring both heavy payload and wide working coverage. It provides a rated payload of 550 kg, a peak payload of 620 kg with the wrist vertically downward, and a maximum reach of 4.2 m.
Breaking the stereotype of slow ultra-heavy-duty robots, this model utilizes optimized counterweights and a parallel link structure, achieving 25% higher operating speed compared with equivalent heavy-duty robots for superior cycle time performance. With a maximum allowable inertia of 725 kg·m², it reliably operates large-volume, wide-span tooling and fixtures. It is well suited for long-distance transportation of large aluminum sheets, wide-range LFAM construction 3D printing, machine tending of large workpieces, and long-distance transfer of castings. It delivers distinct advantages on production lines requiring cross-area operation where robot relocation is impractical.
It inherits the proven mechanical architecture of the IRB 8700 series: single-drive joints paired with purely mechanical counterbalancing, eliminating risks of gas spring leakage and enabling sustained three-shift continuous production. Extended maintenance intervals minimize downtime losses, and spare part costs are lower compared with heavy-duty robots equipped with dual gearboxes.
The robot is factory equipped with the full Foundry Plus 2 protection package with an IP67 rating for dust and corrosion resistance. It supports optional LeanID dress packs to reduce cable abrasion, with full compatibility for offline simulation in RobotStudio. Boasting exceptional structural rigidity, the unit can be expanded with a comprehensive range of advanced motion functions when paired with an OmniCore controller.
