Counteract arm load
The device applies balancing force in opposition to the arm load, reducing the net torque the drive axis must provide at supported positions.

ABB 3HAC024779-001 Balancing Device
A configuration-specific balancing device that counteracts manipulator arm load in its documented ABB robot assembly.
01
Product Information
ABB 3HAC024779-001 is a balancing device used in a documented ABB robot manipulator assembly. Installed between the robot structure and the moving arm linkage, it supplies the counterbalancing force that reduces the net load carried by the associated drive axis as the arm changes position.
The mounting points of ABB 3HAC024779-001 define how balancing force is transferred into the manipulator. Pivot joints must remain aligned and free to articulate; the device is therefore selected from the exact robot serial configuration rather than from length or appearance alone.
Before ABB 3HAC024779-001 is disconnected, the arm is moved to the specified service position and mechanically secured because stored force and gravity can move the linkage. After replacement, joint seating, fasteners and covers are checked before the axis is moved slowly through its permitted range.

03
Product Functions
ABB 3HAC024779-001 works with the manipulator linkage to manage the load seen by the connected robot axis.
Follow joint movement
Pivot connections allow the balancing mechanism to change geometry as the arm moves without becoming a rigid restraint.
Transfer force to structure
Its mounting points return balancing force to the manipulator structure, keeping the load path separate from electrical cabling and controller hardware.
04
Installation Highlights
Stored force and gravity are controlled before fasteners are released; alignment is verified before powered movement.
Secure the manipulator
Move the arm to the specified service position, isolate power and install the required mechanical support so the linkage cannot shift.
Exchange the device
Release force in the documented sequence, preserve pivot hardware and spacers, then seat ABB 3HAC024779-001 without side-loading the joints.
Check the complete range
Inspect fasteners and covers, then move the axis at controlled speed while observing joint articulation, clearance and abnormal mechanical resistance.

Questions & Answers
What does ABB 3HAC024779-001 do in the manipulator?
ABB 3HAC024779-001 provides counterbalancing force to reduce the net arm load carried by the associated robot axis.
Why must the arm be secured before removing ABB 3HAC024779-001?
ABB 3HAC024779-001 acts in a gravity-loaded linkage, so the arm and stored force must be controlled before its mounting points are released.
Can ABB 3HAC024779-001 be selected by physical length?
No. ABB 3HAC024779-001 must be matched to the exact robot type and serial configuration because mounting and force characteristics are configuration-specific.
Which connections should be inspected on ABB 3HAC024779-001?
Inspect the pivot joints, mounting fasteners, spacers and surrounding clearance of ABB 3HAC024779-001 before powered movement.
How should ABB 3HAC024779-001 be tested after replacement?
After installing ABB 3HAC024779-001, move the affected axis at controlled speed and observe articulation, clearance and abnormal resistance through the permitted range.
Does ABB 3HAC024779-001 replace the robot brake?
No. ABB 3HAC024779-001 is a mechanical balancing device; the motor brake remains a separate part of the robot drive system.
