Crane Solutions for Hydrogen Equipment Manufacturing
Hydrogen equipment manufacturing spans four key stages: electrolytic hydrogen production, hydrogen storage, fuel cells, and hydrogen refueling stations. Recommended configurations include the QD Type double-girder crane (16–50t for storage tanks), LD Type overhead crane (5–20t for electrolytic cells/fuel cells), and BZD jib crane (1–5t for precision assembly). Kelude's hydrogen equipment solutions are engineered to meet the special requirements of hydrogen embrittlement resistance, explosion protection, and cleanroom operation.
Cranes for Electrolytic Cell Manufacturing: Stacking & Press Fitting
The core of water electrolysis equipment (alkaline, PEM, and SOEC electrolytic cells) is the cell stack—comprising hundreds of bipolar plates, diaphragms, and gaskets stacked to a height of 1–3 m with a total weight of 5–20 t. Stacking is performed on a dedicated assembly station where plates and diaphragms are layered sequentially and compressed using hydraulic cylinders. The crane is responsible for transporting plates, diaphragms, end plates, and insulation boards from storage to the stacking station.
Recommended Model: LD Type overhead crane (5–16t, span 15–24 m) + BZD jib crane (1–3t). The LD overhead crane handles the transfer of complete cell stacks (5–20t), while the BZD jib crane covers the high-frequency, piece-by-piece handling of bipolar plates (10–50 kg each).
Price Reference: LD overhead crane, 10t/18 m: approximately $12,000–$22,000 per unit. Kelude's electrolytic cell assembly solution uses a vacuum lifter for plate handling—the suction cup never contacts the plate surface, preventing coating scratches.
Cranes for Hydrogen Storage Tank Manufacturing: Plate Bending & Welding
Hydrogen storage tanks (Type I all-steel, Type II steel hoop-wrapped, Type III aluminum liner with carbon fiber, Type IV plastic liner with carbon fiber) are manufactured as follows: ① Types I/II—steel plate bending and welding, with shell diameters of 0.5–3 m, lengths of 3–15 m, wall thicknesses of 10–100 mm, and weights of 5–50t; ② Types III/IV—liner fabrication and carbon fiber wrapping, with liner weights of 200–2,000 kg.
Recommended Model: QD Type double-girder bridge crane (20–50t, span 20–28 m) for Types I/II tank bending/welding + LD Type overhead crane (3–10t) for Types III/IV liner/wrapping. Types III/IV tanks demand stringent liner surface protection—the thin-wall aluminum or plastic liner (2–5 mm wall thickness) is highly susceptible to scratches, and any surface defect becomes a stress concentration point after carbon fiber wrapping.
Price Reference: QD double-girder crane, 32t/22 m: approximately $59,000–$104,000 per unit. Kelude's hydrogen storage tank solution includes a dedicated liner protection lifting spreader with nylon padding and vacuum suction cups.
Cranes for Fuel Cell Manufacturing: Precision Assembly of Bipolar Plates & MEAs
Fuel cells (PEMFC, SOFC, MCFC) are assembled from bipolar plates (500–2,000 g each), membrane electrode assemblies (300–1,000 g each), and gaskets. A single fuel cell stack weighs 20–300 kg. The assembly process requires ISO Class 7 cleanliness—the microchannels on bipolar plates and the catalyst layers on MEAs are highly sensitive to particulate contamination.
Recommended Model: KBK system (0.25–0.5t) + BZD jib crane (0.25–0.5t). The KBK system covers the full fuel cell assembly line—from plate loading, stacking, press fitting, and testing to packaging—with an independent trolley at each workstation. All KBK rails and hoists must feature anti-static configuration (fuel cells contain electronic components and precision coatings; electrostatic discharge can damage the MEA). Cleanroom configuration: stainless steel hoist + HEPA filter breather + PFPE grease.
Price Reference: KBK system, 0.25t cleanroom/anti-static type: approximately $4,500–$9,000 per set. Kelude's fuel cell assembly solution supplies cleanroom cranes configured to ISO Class 7 requirements.
Cranes for Hydrogen Refueling Station Equipment: Compressor, Cylinder Bank & Dispenser Assembly
Core refueling station equipment includes hydrogen compressors (piston or diaphragm type, 500–5,000 kg), hydrogen cylinder banks (multiple cylinders grouped, 1,000–5,000 kg), and hydrogen dispensers (with flow meters, heat exchangers, and control panels, 200–800 kg). Manufacturing these components presents two distinct challenges: ① Hydrogen medium requirements—all hydrogen-contact components must undergo degreasing, and lifting tools must be completely free of grease contamination; ② Explosion protection—hydrogen is a flammable and explosive gas (explosion limit 4–75%), placing the workshop in an explosion-proof zone.
Recommended Model: LD Type overhead crane (5–16t) + KBK system (0.5–1t). All cranes must be explosion-proof type (Ex ⅡC T4/H2 explosion protection class), and lifting spreaders that contact hydrogen piping or valves must be degreased—any grease residue can introduce impurities into the refueling station equipment.
Price Reference: LD overhead crane, 10t explosion-proof type: approximately $27,000–$45,000 per unit. Kelude's hydrogen refueling station solution includes degreasing services for all lifting spreaders plus a factory grease inspection report.

Frequently Asked Questions (FAQ)
Q: What special anti-corrosion requirements do hydrogen equipment manufacturing facilities impose on cranes?
A: Hydrogen in the manufacturing environment is highly permeable and can penetrate steel, causing hydrogen embrittlement. Therefore: ① Coating — the crane steel structure must use an epoxy zinc-rich + epoxy micaceous iron oxide + polyurethane coating system with a total thickness of ≥200 μm to prevent hydrogen from reaching the steel surface; ② Stainless steel substitution — in hydrogen compressor, hydrogen storage tank, and hydrogen dispenser assembly areas, SUS304 stainless steel hoists are recommended (carbon steel exposed to hydrogen over time will embrittle and crack); ③ Galvanizing — hot-dip galvanized components are not recommended (zinc has poor corrosion resistance in hydrogen environments, and micropores in the zinc layer can become hydrogen accumulation points). Kelude's hydrogen equipment crane solutions use an epoxy zinc-rich coating system with an optional stainless steel hoist.
Q: What configuration is required for a cleanroom crane used in fuel cell assembly?
A: Fuel cell bipolar plates and membrane electrode assemblies are extremely sensitive to particulate contamination — a 10 μm particle landing on a membrane surface can penetrate the proton exchange membrane (which is only 15–50 μm thick), causing hydrogen and oxygen to mix inside the membrane (a safety hazard). The cleanroom-grade configuration includes: ① SUS304 stainless steel construction (no rust particles); ② TEFC totally enclosed fan-cooled motor (zero cooling-air particle emission); ③ PFPE perfluoropolyether grease (non-volatile, non-shedding); ④ HEPA H14 filtered breather (positive pressure inside the hoist keeps external particles out); ⑤ Total machine particle emission ≤0.1 μg/cm² (verified per ISO 14644-14). Kelude's fuel cell cleanroom cranes are already in operation at multiple hydrogen energy companies.
Q: What lifting and transport protection options are available for hydrogen tank liners?
A: Type III/IV hydrogen tank liners are made of aluminum alloy (2–5 mm wall thickness) or plastic (3–8 mm wall thickness) and are extremely thin. Lifting damage (scratches, dents, punctures) is unacceptable — the high tension during carbon fiber winding (400–800 MPa) can cause surface scratches to propagate into cracks, leading to liner leakage in service. Protection options: ① Vacuum lifters — suction cups 60–80 mm in diameter with 50–100 kg lifting force each, evenly distributed to lift the liner (suitable for flat surfaces); ② Nylon lifting nets — a flexible net that fully wraps the liner with mesh openings ≤20 mm × 20 mm (suitable for irregularly shaped liners). Kelude provides custom liner lifting solutions selected based on the customer's liner material (aluminum alloy or plastic) and shape (cylindrical or spherical).
Q: What is the typical investment for cranes in the hydrogen equipment industry?
A: The investment depends on the crane type, capacity, and configuration. A standard explosion-proof crane for hydrogen refueling stations typically ranges from $15,000 to $45,000, while a cleanroom crane for fuel cell assembly with stainless steel construction and HEPA filtration typically ranges from $30,000 to $104,000. Kelude provides tailored proposals based on your specific lifting requirements, cleanliness level, and explosion protection class.
A: Using an annual production of 100 electrolytic cells + 50 fuel cells as an example: ① Electrolytic cell assembly area: 1 LD 10t + 2 BZD hoists (approx. $16,600); ② Hydrogen storage tank plate bending area: 1 QD 32t + liner assembly area: 1 LD 5t (approx. $77,100); ③ Fuel cell assembly area: 3 KBK cleanroom systems (approx. $17,800); ④ Hydrogen refueling station equipment area: 1 explosion-proof LD 10t (approx. $37,100). Total investment: approximately $155,700. Benefits: Electrolytic cell stacking efficiency improved by 40% (vacuum lifter enables rapid piece-by-piece lifting and transport); fuel cell assembly cleanliness compliance rate increased from 70% to 100% (cleanroom crane + ISO Class 7). Payback period: approximately 14–18 months.
