Direct answer. Use the workpiece type and the weld to be made—not the catalogue name—to choose a WUXI ABK starting family. Cylindrical shells and pipe that must rotate for girth welding start with an HGK adjustable or HGZ self-aligning welding rotator. Longitudinal seams start with an LH column-and-boom manipulator. Heads, nozzles, flanges and short fixtures that need tilt plus rotation start with an HBJ positioner or HB turntable. Published HGK/HGZ ratings are for one standard set (one drive unit + one idler unit) under an evenly distributed concentric load. Final model, support arrangement and options are confirmed in the signed technical specification.
Read the row that matches the workpiece and the joint. Then open the linked series page and send the RFQ inputs at the end of this page.
| Workpiece | Process / joint | Start with | Confirmed public models | Leave the table if |
|---|---|---|---|---|
| Cylindrical vessel / tank shell | Circumferential / girth | HGK or HGZ rotator | HGK-10 / 50 / 200; HGZ-10 / 50 / 100 | Fit-up travel, extra idlers or rating above the published set is required |
| Cylindrical vessel / tank shell | Longitudinal seam | LH manipulator | LH-3030, LH-8080, LH-80150 | Torch, seam tracking and power source are buyer-supplied unless listed |
| Cylindrical vessel / tank | Head, nozzle or flange orientation | HBJ positioner or HB turntable | HBJ-06 / 12 / 50; HB-10 / 30 / 50 | Workpiece needs continuous rotation of a long cylinder — use a rotator |
| Cylindrical vessel / tank | Shell-to-shell fit-up | Hydraulic fit-up rotator system | Project-specific | Do not pick a catalogue tonnage from HGK/HGZ alone |
| Wind tower section | Circumferential / girth | HGK or HGZ rotator | Same rotator table | Complete growing line, canter or lifting arrangement is project-specific |
| Wind tower section | Longitudinal SAW | LH manipulator | LH-3030, LH-8080, LH-80150 | Envelope, foundation and welding head must be stated |
| Wind tower section | Complete section / growing line | Engineered wind-tower package | Project-specific; see the wind-tower page | Do not infer a standard maximum from a marketing line page |
| Pipe spool / pipe section | Circumferential | Rotator if long/heavy; HBJ/HB if short and ≤5 t | HGK/HGZ table or HBJ/HB table | Eccentric fittings change both support load and traction |
| Pipe spool / pipe section | Longitudinal | LH manipulator | LH-3030, LH-8080, LH-80150 | Same interface rule as vessel long seams |
| H-beam / structural steel | Long-seam SAW head positioning | LH manipulator | LH-3030, LH-8080, LH-80150 | A full cut–assemble–weld–straighten–blast line is project-specific |
| H-beam / structural steel | Small assembly / fixture | HBJ or HB | HBJ-06 / 12 / 50; HB-10 / 30 / 50 | Do not treat a positioner as a beam line |
| General part / fixture | Tilt and rotate | HBJ or HB | Same positioner / turntable table | Cylindrical production welding still belongs on a rotator |
HGK versus HGZ. Choose HGK when roller spacing must be set for changing diameters. Choose HGZ when the self-aligning cradle should follow diameter inside the approved range. Both families use the same published rating convention.
Select from the maximum complete rotating or positioned weight, including flanges, internals, fixtures and temporary attachments. Do not select from empty-shell weight.
| Complete weight | Geometry | First public models to discuss | Rating note |
|---|---|---|---|
| ≤ 0.6 t | Needs tilt / table | HBJ-06 (table 800 mm) | Positioner rating is the table load in the approved attitude, not a rotator set |
| ≤ 1 t | Needs tilt / table | HBJ-12 (1.2 t, table 1,000 mm) or HB-10 (table 800 mm) | Confirm eccentricity and fixture mass |
| ≤ 3 t | Needs rotate, limited tilt | HB-30 (table 1,200 mm) | Confirm duty and table size |
| ≤ 5 t | Needs tilt / table | HBJ-50 (table 1,500 mm) or HB-50 (table 1,500 mm) | If the part is a long cylinder, prefer a rotator |
| ≤ 10 t | Long cylinder | HGK-10 or HGZ-10 | Standard set = 1 drive + 1 idler, concentric, even load |
| ≤ 50 t | Long cylinder | HGK-50 or HGZ-50 | Same set definition |
| ≤ 100 t | Long cylinder | HGZ-100 | Same set definition |
| ≤ 200 t | Long cylinder | HGK-200 | Same set definition |
| Above the published set, or HGK-500 class | Heavy cylinder | Engineering review. HGK-500 is a documented reference configuration only | Re-check load, diameter, speed and wheel data before quoting |
| Model | Rated set capacity* | Surface speed | Workpiece diameter |
|---|---|---|---|
| HGK-10 | 10 t | 100–1,000 mm/min | 400–4,000 mm |
| HGK-50 | 50 t | 100–1,000 mm/min | 400–6,000 mm |
| HGK-200 | 200 t | 100–1,000 mm/min | 800–8,000 mm |
| HGZ-10 | 10 t | 100–1,000 mm/min | 400–3,500 mm |
| HGZ-50 | 50 t | 100–1,000 mm/min | 800–5,000 mm |
| HGZ-100 | 100 t | 100–1,000 mm/min | 1,000–6,000 mm |
*Rated capacity refers to one standard set comprising one drive unit and one idler unit under an evenly distributed concentric load. Individual-unit support load, tractive capacity, eccentric load, extra idlers and safety margin must be defined in the signed technical specification.

Does the published rotator capacity refer to one roller stand?
No. For public HGK and HGZ tables it refers to one standard set: one drive unit plus one idler unit, under an evenly distributed concentric load.
Can I select only by tonnage?
No. Diameter, support spacing, eccentricity, traction, wheel material and duty can rule out a catalogue size that looks large enough by weight.
Which model for a wind-tower can section?
Start with the rotator table for girth rotation and an LH manipulator for longitudinal SAW. A full growing line is engineered after section weight, diameter, length, process and shop layout are known.
Do you hold ASME or PED as company certificates?
No. WUXI ABK holds ISO 9001 as a quality-management-system certification. ASME, PED, API and EN 1090 are treated as purchaser/project standards. CE documents and third-party inspection are order-specific.
