IRB 8700

In designing the IRB 8700 the
focus was on delivering a very
reliable robot with a low total
cost of ownership. Through a
combination of robust design
elements, including simpler parts
configurations where possible,
ABB Robotics applied decades
of engineering experience to
combine the high performance
customers require with low
overall maintenance needs.
In addition, the IRB 8700 delivers 25% faster speeds than any
other robot in this class size.
Two configurations
The IRB 8700 comes in two configurations, one with a reach
of 4.2 meters and a payload of 550 kg (620 kg with the wrist
down; 475 kg with LeanID) and another with a reach of 3.5
meters and a payload of 800 kg (1000 kg with the wrist down;
630 kg with LeanID). Both configurations have an incredibly
high moment of inertia at 725 kgm2.
Outstanding reliability
With a straightforward and uncomplicated design that uses
world-class components, LeanID for the best cost-toendurance ratio in a dress pack, and ABB’s Foundry Plus 2
as standard protection, the IRB 8700 will run with very high
uptime—a key feature in production lines that operate around
the clock.
Simplified design
The IRB 8700 has only one motor and one gear per robot
axis, while most other robots in this size class use dual
motors and/or gears. In addition, there are no gas springs
that can leak and cause safety problems, only a reliable

counterweight and mechanical springs for counter balancing.
Together these design elements mean the IRB 8700 has fewer
components to fail while delivering shorter cycle times and
higher accuracy.
Built around LeanID
With LeanID, ABB has developed a concept that is less
expensive than completely integrated dress packs but still delivers most of the benefits for a fraction of the cost. LeanID results in a robot that is easy to simulate in offline programming,
has a long dress pack lifetime, supports flexible production
with a large working range, and can easily enter tight spaces.
Fast
High payload robots are typically known as being very slow,
but the IRB 8700 turns these assumptions on their head. With
a compact footprint, optimized counterweight, parallel linkages,
stiff axes, and fewer drive motors, the IRB 8700 keeps its momentum down and speed up. In fact, all of these improvements
add up to a robot that is 25 % faster than any other robot in its
size class. In addition, thanks to superior motion control at high
moments of inertia (725 kgm2) the robot can adapt, or slow its
speed, to accommodate heavy and wide parts.
