        More Information

        Overview Manuals Energy Control Shaft Matching Lift & Closure Product Applications

        Features:

        • Rear-frame assembly: ABB locates the balancing device behind the IRB 6700 arm structure
        • Stored-energy control: a dedicated hydraulic press unloads the spring unit
        • Variant-sensitive hardware: the front link-ear shaft determines its matching cover or plug
        3HAC043477-002 is the complete IRB 6700 balancing device, distinct from the link-ear bearing kits and shaft components used during overhaul.

        Its removal is a lifting and stored-energy operation that requires dedicated ABB press tooling before any load-bearing shaft is released.

        Receiving and maintenance teams should align the exact robot variant with the installed shaft version and cradle hardware before scheduling work.
        Apter Power can review 3HAC043477-002 article evidence, robot variant, external condition, lifting scope, and documented service requirements.

        Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
        • Spring unloading: use hydraulic press equipment 3HAC074411-001
        • Tool instructions: follow the user document enclosed with the press
        • Cover restriction: remove only the rear-cover attachment screws
        • Arm restraint: secure the lower arm with the specified lock screw before shaft work
        • Earlier shaft: 3HAC044036-001 uses VK cover 3HAA2166-12
        • Later shaft: 3HAC072597-001 uses protection plug 3HAC4836-26
        • Cradle covers: two 90x12 VK covers are documented
        • Selection rule: identify the installed link-ear shaft before ordering consumables
        • Lifting point: attach the shackle and ABB chain to the supported device
        • Seal service: inspect link-ear seals, O-rings, and cradle covers
        • Fastener retention: use the specified locking liquid where the procedure calls for it
        • Corrosion protection: allow the documented Waxcoat drying interval before release
        • IRB 6700 counterbalance replacement: exchange the complete rear-frame balancing assembly
        • Stored-energy maintenance: unload and restrain the spring unit with ABB equipment
        • Link-ear overhaul planning: match the shaft, cover, seals, and bearing hardware
        • Heavy component sourcing: verify lifting, access, condition, and variant records before dispatch
        Description
        Mounted at the rear of the IRB 6700 frame, 3HAC043477-002 is ABB's balancing device for the manipulator arm system. The exact article identifies a large mechanical assembly rather than a bearing, shaft, maintenance kit, or unloading tool.

        Replacement of 3HAC043477-002 begins by unloading its stored spring force with ABB's dedicated hydraulic press equipment. The lower arm is then secured, lifting accessories are attached, the front and rear shafts are removed, and the device is lifted clear under controlled support.

        Planning for 3HAC043477-002 must preserve the IRB 6700 variant, shaft-link-ear version, cradle condition, seal and cover arrangement, available clearance, and lifting plan. These details determine the correct consumables and safe mechanical sequence.
        Alternative Names
        3HAC043477002 ABB IRB 6700 balancing device IRB 6700 counterbalance assembly ABB robot arm balancing unit
        Technical notes
        3HAC043477-002 contains stored mechanical energy and must be unloaded only with ABB hydraulic press equipment 3HAC074411-001 and its enclosed instructions. Never remove screws other than the rear-cover fasteners during unloading. Secure the lower arm before shaft work, and size lifting accessories for the documented robot variant.

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Why must 3HAC043477-002 be unloaded before either support shaft is removed?
        The assembly contains stored spring energy. ABB requires the hydraulic press equipment to unload and lock the device before the front or rear support is released.
        Which press system is specified for service on 3HAC043477-002?
        Use ABB hydraulic press equipment 3HAC074411-001 with its enclosed instructions; the related hydraulic pump is rated at 70 MPa.
        How is the lower arm protected during removal of 3HAC043477-002?
        Fit the M16x120 lock screw through the frame into the lower arm, or use an equivalent documented restraint, before removing the load-bearing shaft.
        What decides the front link-ear cover used with 3HAC043477-002?
        Identify the shaft first: 3HAC044036-001 uses VK cover 3HAA2166-12, while 3HAC072597-001 uses protection plug 3HAC4836-26.
        Why should the work area around 3HAC043477-002 be cleared before movement tests?
        ABB requires the space inside the frame to remain free of tools or other objects that could obstruct balancing-device travel.
        What evidence should procurement provide when sourcing 3HAC043477-002?
        Send the full article label, IRB 6700 variant and serial number, installed shaft and cradle photos, leak or damage findings, quantity, destination, and lifting restrictions.
