Use of Multi-Purpose Cart

Use of Multi-Purpose Cart

In the field of aircraft maintenance, equipment such as a multi-purpose cart allows the compliance of different kinds of maintenance servicing tasks with the advantage of portability and efficiency.

Within the cart itself are sets of generators, pumps, filters, electrical outlets, nitrogen cylinders and different sets of gauges which are all designed to perform separate functions but are packed together, hence the moniker, “Multi-Purpose Cart.”

Generators and its accompanying electrical outlets can be used by technicians to provide electrical power to tools or equipment such as portable lamps, air compressors and ventilation machines. This design capability is most applicable when technicians are working at night and requires illumination to work safely or are working on maintenance tasks that require sufficient ventilation such as entering of aircraft fuel tank or entering inside a cargo compartment.

Hydraulic pumps, filters and hoses are collectively used to drain and refill the fluid currently stored inside the hydraulic reservoir. With the use of this equipment, the completion time of the maintenance task is significantly faster as a pressurized vacuum will drain the stored fluid in the reservoir and a pressurized pump will refill the reservoir with new fluid. This eliminates the conventional work of manually draining by using gravity and refilling with the use of a manual hand pump.

The cart is also equipped with nitrogen cylinders, hoses and pressurized gauges. These components are used to check, inflate or deflate aircraft tires. It is also used to service the landing gear shock absorber with nitrogen. On certain aircraft, nitrogen servicing is also performed on tail bumpers or in the actuator that enables emergency opening of passenger doors.

 

Multi-Purpose Cart Upkeep and Maintenance

As with any mechanical device, proper upkeep and maintenance is a must to ensure that the equipment will function properly and accurately. This upkeep also ensures that the total investment made in the equipment itself will be maximized.

A proper maintenance program to be deployed in a Multi-Purpose Cart would see the inspection and servicing of the following parts:

  • Generator – This component can be considered as one of the most important part of the Multi-Purpose Cart as it supplies electricity to the different components such as pumps, illumination and ventilation. Proper upkeep and maintenance would see the inspection and servicing of the wiring, coolant and fuel lines.
  • Oil Reservoir, Pumps, Hoses and Filters – As this component enables the supply of pressurized fluid to and from the hydraulic reservoir. It is important to check and perform servicing on the O-rings and seals of the pump to avoid leakage. Ideally, filters should be replaced discarding foreign materials that have been strained.
  • Nitrogen Cylinder, Hoses and Pumps – Allows the refilling of nitrogen for different aircraft servicing tasks. A nitrogen leak can result in an explosion if combined with heat and a spark. It is very important to make sure that the hoses are free from punctures and the gauge accurately displays the nitrogen pressure stored inside the cylinder.
