What Are Boeing 737 Jacks?
Boeing 737 jacks are specialized lifting devices used to support and position the aircraft during maintenance, inspections, and ground handling. They are designed to fit specific jack points on the fuselage, wings, and nose to ensure stable, level lifting. Using the correct jack type prevents structural damage and improves safety during ground operations.
Types of Jacks Used on the 737
Common jack types include hydraulic bottle jacks, tripod jacks, and knee jacks. Hydraulic bottle jacks are often used at main landing gear and fuselage lift points. Tripod jacks provide stability at wing and body stations, while knee jacks support the nose area. Each jack must match the aircraft's weight rating and be used at designated hard points only.
Safety and Operational Guidelines
Operators must follow Boeing technical documentation and use certified jacks with proper load ratings. Before lifting, the aircraft should be on a level surface, and jacks should be secured with safety stands. Regular inspections, proper training, and adherence to load limits help prevent accidents.
