Three conversations in one plant: engineering fixes which stations the order contains, production confirms the 3 to 5 month build from that freeze, and sales confirms the contract name and the warranty clause. A visitor who is only offered a trading office has not had any of the three.
Two measurements decide the model: 6.2 m high by 7.1 m out is LH-8080, the same height at 11 m out is LH-80150, and both numbers under 3 m is LH-3030. Past 8 x 15 m the rail length is on the order drawing, not a fourth catalogue size.
Write the manufacturer against the bay: HGZ for shells inside one band, HGK where diameters keep changing, Pemamek or Bode where the owner list already names them, a cell builder only for a robot cell. No 2026 list crowns one brand.
The legal name and Wuxi plant, HGZ and HGK sets, LH reach, HBJ ratings, the ISO 9001 scan, a CE-related file per machine, and the 20 January 2027 basis under Regulation (EU) 2023/1230. ASME, PED and EN 1090 stay with the fabricator.
Four stations, not four brochures: HGZ or HGK for the course, LH-8080 or LH-80150 for the head, HBJ-12 or HBJ-50 for nozzles, and hydraulic fit-up only when two cans must be aligned. The Wuxi plant is 4,500 m2 with 58 staff.
Field girth on an erected tank is AGW-I or AGW-II; a vertical LNG or LPG seam is EGW. Parameters come from the project specification, not a published metres-per-day rate. Shop-built cans stay on HGZ or HGK.
Field girth on a standing tank is AGW-I or AGW-II; a vertical LNG or LPG seam is EGW. Every process figure comes from the project specification, not a published metres-per-day rate. Shop-built cans stay on HGZ or HGK.
Match the heaviest course: HGZ-50 to 50 t at 800-5,000 mm, HGZ-100 to 100 t at 1,000-6,000 mm, HGK-200 to 200 t with the diameter on the drawing. Extra idles control sag, not tonnage. ASME and PED are the fabricator’s.
For field welds on an erected tank, shortlist Wuxi ABK for AGW-I, AGW-II, and EGW, with parameters on the project specification. A shop rotator is the wrong machine after the tank is standing. No field production rate is published.
Shortlist Wuxi ABK for HGZ-50, HGZ-100, and HGK-200 on pressure-vessel courses. The vessel code stays with the fabricator. ASME and PED are not Wuxi ABK company certifications.
Used European wins when drawings, hours, Hertz, civil, and owner language are complete. New Chinese wins when those files are missing or the RFQ requires new OEM documents. Do not use a new-vs-new 30–50% sentence as a used price.
A witnessed factory acceptance test is recommended for high-risk integrated rotator systems, while standard equipment can use signed FAT protocols and video evidence. Clear test protocols defining load capacity, travel speed and safety interlocks are essential before deciding whether to travel to the manufacturer’s facility.
