The landing gear system is one of the most important subsystems of an aircraft and therefore it is often has a significant impact on the aircraft structural configuration. An aircraft’s landing gear is a shock-absorbing system that dampens the stresses that the aircraft encounters during landing, take-off, and during its movements on the ground on its power or when it is towed. It converts the kinetic energy of the impact into heat which dissipates in the environment through the structure of the landing gear. The landing gear also helps in slowing and stopping the aircraft by wheel brakes. The nose wheel steering system gives the pilot directional control of the aircraft on the ground. On larger aircraft, the landing gear is almost always designed to be retractable to reduce air drag while the aircraft is flying.
A landing gear system comprises many structural and system components. They include struts, shock absorbers, axle, wheels, brakes, actuators, braces, locks structural fittings, etc. The nose landing gear has an additional mechanism to steer the aircraft on the ground.
Long life and minimum maintenance requirements are vital for reducing operational and maintenance costs while minimizing the overall life cycle cost. The landing gear is the most maintenance-intensive system of the aircraft next only to its engines.
The landing gear of an aircraft operates in a harsh environment. The pressurized oleo-pneumatic shock-absorbers which are the key elements in the landing gear system exert extreme pressure and stress on his housing structure. However skillful the pilot is, on landing the aircraft, the forces generated by the impact on the runway induces heavy stresses on the entire structure of the aircraft. Immediately after landing, the braking action required to slow down and stop the aircraft produces horizontal stresses. These horizontal stresses also occur during take-off when the aircraft roars to full take-off power.
While on the ground, with the engines shut down, a tow truck is used to move the aircraft. Towing puts stresses on the nose gear, especially if the towing is not done gently. The aircraft often encounters debris and other unwanted objects on the tarmac which can damage the landing gear while the aircraft is moving on the ground.
While under maintenance in the hangar, the landing gear can be mishandled by poor jacking and inept handling which can damage it. Even the apparently simple job of cleaning the landing gear with a high-pressure water stream can cause problems, as the water can enter into the bushings and joints, which can accelerate corrosion in the long run. Some solvents like paint strippers if used inappropriately can also damage the landing gear.
There are several types of equipment that are required to service the aircraft landing gears. Landing gear dollies are very useful to transport wheels safely and with ease. Safe and efficient transport of wheels is important and these aviation dollies help to do just that. There are also special dollies for the wheel, landing gear, as well as wheel and brake dollies all part of ground service equipment.
This equipment is designed to service and transport aircraft landing gear. It is sturdily constructed with welded steel. It has a manually operated hydraulic hand pump. It has large diameter swivel casters for greater maneuverability in all directions. Specific models are required for each type of aircraft.
This equipment is designed to handle the wheel brake system. It has a strong welded steel construction. It has a manually operated hydraulic hand pump. There is a strap assembly for securing the load to the dolly. It has an adjustable rear swivel caster for tilting the dolly and front swivel casters with floor locks. There is a padded brake handling adaptor.
This equipment is designed to safely and efficiently workout aircraft landing gear struts to remove air while servicing them. It has a low profile to fit under most aircraft wings and minimizes the risk of damage to the aircraft by its pneumatic lifting operation. It has a standard adapter that fits most aircraft. The equipment can be operated by a single technician.
This is a service tool for struts, brakes, and tires. It has a low profile and there is no need to remove the tire when servicing the struts. It has a long handle for ease of lifting and a wide, heavy-duty steel turntable which can be used for both nose and main tires. It has a clamp that easily locks the tire in place. It has 2 swivel casters for easy maneuverability with no-mark rubber wheels.
A high-quality wheel dolly is a piece of equipment that can save you from a variety of issues. With a sturdy steel construction and corrosion-resistant steel rollers, a good wheel dolly can provide useful service for a long time. It is used to transport aircraft wheels for servicing and maintenance.
