ABB IRB 7720-400/3.3
The ABB IRB 7720-400/3.3 is a heavy-duty 6-axis industrial robotic arm developed by ABB for high-payload material handling, press tending, machining and large-scale assembly applications.
It features a 400kg payload, 3300mm reach and 0.05mm position repeatability, enabling precise and reliable handling of very heavy components across large industrial workspaces.
