Overhead Crane Solutions for Aerospace Manufacturing
At a Glance: Kelude Heavy Industry provides crane configuration solutions for aerospace manufacturers across four key production stages—airframe structure, engine manufacturing, landing gear assembly, and final assembly. With lifting capacities from 1 to 80 t and spans from 8 to 42 m, the total investment for plant-wide lifting equipment typically ranges from approximately $60,000 to $890,000. The airframe structure workshop is equipped with large-span overhead cranes (20–50 t), the engine manufacturing area uses precision overhead cranes with creep speed control (5–20 t), the landing gear assembly zone features heavy-load overhead cranes (32–80 t), and the final assembly line utilizes KBK multi-point suspension systems with custom lifting spreaders (1–5 t)—all engineered to meet aerospace requirements for cleanliness, precise positioning, and oversized component hoisting.

Lifting Challenges Across Aerospace Manufacturing Stages
Aerospace manufacturing demands far greater precision and safety from lifting equipment than general industry applications. Each of the four core production stages presents its own unique operating conditions. In airframe fabrication—machining of wings, fuselage sections, and tail assemblies—single-piece lifting loads range from 5 to 30 t with spans of 18 to 30 m. The critical requirement here is flip-and-align accuracy: cranes must be equipped with electronic anti-sway systems (swing ≤ ±30 mm) and two-speed hoisting (high speed at 6 m/min, micro-motion at ≤ 0.5 m/min). Lifting spreaders use vacuum lifters combined with mechanical locks as a dual safeguard against surface damage to large components. Engine manufacturing (turbine discs, casings, blades) involves loads of 3 to 20 t, with assembly areas requiring controlled temperature and humidity (20 ± 2 °C / RH ≤ 45%). The recommended solution is a KBK suspension system with pneumatic balancers (positioning accuracy ≤ ±1 mm), and the electrical control system must be anti-static by design (grounding resistance ≤ 4 Ω). Landing gear production—covering forging, heat treatment, and finish machining—handles loads of 10 to 50 t, with individual struts weighing 3 to 8 t. This calls for heavy-duty underslung cranes or jib cranes, plus high-temperature-resistant (≤ 500 °C) electric hoists at heat-treatment stations. Avionics and weapons mounting require electromagnetic compatibility (EMC), making manual KBK systems the preferred choice—no motors, no electromagnetic radiation—with mounting accuracy of ±0.5 mm aided by laser guidance. Kelude delivers differentiated lifting solutions tailored to each of these four aerospace manufacturing stages, featuring imported key components (SEW-Eurodrive/ABB drives, KUKA anti-sway algorithms) and full AS9100D aerospace quality management system certification.
Kelude has specialized in aerospace manufacturing lifting systems for years, supplying extra-wide-span, ultra-high-precision, and cleanroom-compatible crane solutions to Airbus and Boeing subcontractors as well as COMAC suppliers. All products are certified to the AS9100 aerospace quality management system.
