Gear Drives & Actuators in Aircraft Dock Maintenance Platforms

Aircraft dock maintenance platforms require precise lifting, smooth motion control, and absolute reliability to ensure safe access to the fuselage, tail, and engine areas during inspection and servicing. These platforms must operate flawlessly in outdoor environments, often exposed to extreme temperatures, high humidity, and continuous mechanical load.

NUODUN supplied a customized system of high-reliability gear reducers and electromechanical actuators engineered specifically for aviation ground support equipment (GSE), including maintenance docks and engine test stands.

Application

The platform shown integrates multiple NUODUN worm-gear reducers and screw-jack actuators to control vertical lifting, leveling, and platform positioning. These motion units provide synchronized adjustment of multi-level access structures, ensuring stable alignment with the aircraft tail and fuselage.

Key Functions

• Precise height and position adjustment
  Ensures safe and accurate alignment of multi-level maintenance platforms around the aircraft structure.
• High load-bearing capability
  Designed to support the full weight of steel platform structures and dynamic loads from maintenance personnel and equipment.
• Reliable operation in extreme temperature environments
  Specialized lubrication and materials provide stable performance from –50°C to +120°C, suitable for harsh outdoor airport conditions.
• Smooth synchronized lifting
  Multi-actuator systems maintain platform levelness and structural stability during movement.
• Low maintenance, long service life
  Hardened gear surfaces, sealed housings, and corrosion-resistant coatings ensure durability even in coastal or high-humidity environments.
