Position-dependent force
The device's geometry changes as the upper arm moves. That force relationship assists the axis drive without replacing the motor, brake or controller's position regulation.

ABB 3HAC043477-002Balancing Device
01
Product Overview
ABB 3HAC043477-002 is the Graphite White balancing device used on applicable ABB IRB 6700 manipulators. It counterbalances the upper-arm load so the axis drive works against a controlled spring or gas-force relationship instead of carrying the entire gravitational moment alone.
Mounted between the robot structure and the moving arm, ABB 3HAC043477-002 changes force as the arm travels through its range. Its attachment points, pressure or spring condition and mechanical alignment work with the axis motor and gearbox; the device does not issue an electrical control signal.
Service on ABB 3HAC043477-002 starts with positioning and supporting the robot so stored mechanical energy is controlled. The exact IRB 6700 reach and payload execution is confirmed, attachment hardware is transferred in the documented sequence, and the arm is moved slowly to verify clearance and balanced behavior.

Operating Characteristics
ABB 3HAC043477-002 changes its balancing force with arm position so the robot drive sees a moderated gravitational load throughout the working range.
Stored mechanical energy
Balancing force remains present even when electrical power is removed. The arm and device must therefore be supported and released only through the documented mechanical sequence.
Drive-load interaction
A healthy balance device reduces the gravitational component seen by the axis drive. Binding, incorrect attachment or lost force can appear as uneven current or motion across the arm range.

Installation Highlights
Install ABB 3HAC043477-002 by controlling the arm position, stored energy and exact attachment geometry from removal through functional verification.
Stabilize the robot
Move to the specified service position, remove payload influence where required, isolate energy and mechanically support the upper arm before loosening either attachment.
Transfer the device
Use the prescribed lifting and release points, keep body and tools outside the force line, and fit the replacement to the correct IRB 6700 mounting locations without forcing the joints.
Check the full range
Restore guards and hardware, then move the arm slowly through the permitted range while checking clearance, balance behavior, drive current and absence of binding.
