Aircraft Dolly Calibration Check List

Aircraft Dolly Calibration Check List

Aircraft dollies are required to aid the moving of aircraft in and out of hangers to prepare the aircraft for flight. The dolly moves the aircraft by either attaching to the wheel frame or lifting the single tire in the air and moving.

 

Aircraft Dolly Design

Three different designs for aircraft dollies can be found below:

Power method:

  • Gasoline Internal Combustion Engine. A small-displacement gasoline engine is currently a common method used to power aircraft dollies or tugs.
  • D/C Electric. Direct current or D/C electrical power is the use of direct current electricity to run a motor of the required voltage. This motor will provide the dolly with the needed power to move the aircraft in and out of its storage site.

Lifting Moving Method:

  • Ramp/Scoop and Tilt Method. This is the most common method used in the industry for larger commercial type aircraft.
  • Crimp and Lift Method. The crimp and lift method is a very effective method to transport aircraft.
  • Axle Clasp Method. The axle clasp method is the original aircraft moving method and machines all over the world can be found being moved with this simple clasp design. This method allows the movement of an aircraft without the physical lifting of the machine.

Steering Method:

  • The Single Tire is usually accompanied by the axle clasp method to attach to the aircraft. Once securely attached, the user must place a downward force on the dolly to provide enough traction for moving.
  • The triple Tire design or geometry is primarily used alongside a lift and scoop method, or a method that physically picks up the aircraft and transports it to and from its storage site.
  • The Iron Tire has a multi-directional frame and does not rely on single-direction pulleys or wenches. This makes the process of separating the aircraft from the dolly quick and easy.

 

Aircraft Dolly calibration / maintenance

To ensure your aircraft dolly is functioning to the best of its capability, certain maintenance procedures must be followed.
e2b calibration has compiled a checklist to ensure your aircraft dolly is properly maintained and repaired:

  • Lubricate all-wheel truck swivel with general purpose grease annually
  • Disabled aircraft dollies should be stored in a clean, dry area when not in use
  • Check pump, reservoir, and lines for leaks
  • Inspect the pump, cylinder, hydraulic fittings, and hose for hydraulic leaks. Replace seals if any leaks exist.
  • Check fluid level in the pump
  • Check for bending, cracking, and dents in dolly
  • Inspect wheels for proper pressure; repair any leaks or replace them if needed. Ensure the wheels can rotate freely, and wheel rims and tire axles are not bent.
  • Check towing eye for bending, excessive wear, and/or deformity
  • Check to tow eye mounting bolts, ensure fasteners are not lost or missing.
  • Check to tow eye mounting bolts. Ensure the fasteners are tight and not missing.
  • Check chains for excessive wear
  • Check retraction pins for bends and cracks

To avoid all the problems of record-keeping and record retrieval related to your aircraft maintenance. e2b calibration provides the option to use Anytime Assets, its cloud-based asset management system where you can find all required information related to your calibrations, certificates, records as well as get notifications on the maintenance / calibration due dates.  For more information about our services contact e2b calibration.
