Now ultra-modern equipment at airport for smoother landings

NEW DELHI: Delhi International Airport (Private) Limited has acquired a state-of-the-art runway de-rubberising equipment to improve runway maintenance and pave the way for smoother landings at Indira Gandhi International Airport here.

This ultra-modern equipment — “TrackJet” — utilises a revolutionary high-pressure water-jet technology to clean up rubber deposits on the runway surface. These deposits are formed due to friction between the wheels of a landing aircraft and the surface.

Rubber deposits accumulated over a period of time tend to reduce the grip available to an aircraft during landings. Hence to ensure the highest safety levels, these deposits are removed periodically.

“Cleaning with ‘TrackJet’ technology provides optimum level of friction as stipulated by the International Civil Aviation Organisation.

Traditional cleaning methods are slow and involve intensive manual labour, while achieving only moderate results. ‘TrackJet’ technology can remove rubber deposits at the rate of 800 square metres per hour with the help of just one operator,” said a DIAL spokesperson.

“Also, traditional methods carry the risk of damaging the runway, while the high pressure water-jet technology causes no damage to the runway and can increase its life span. DIAL’s sister concern that will operate Rajiv Gandhi International Airport in Shamshabad, Hyderabad has also procured this equipment,” he added.

For construction of a new passenger terminal and runway, DIAL claims to have employed some of the best equipments.

“Eight Vibratory Soil Compactors with 18-tonne capacity have been exclusively imported from Germany for this project. These are being used for embankments and stabilising the base soil of the runway.

“These machines are equipped with the latest microprocessor technology for the best results. Also, ten Electronic Sensor Pavers built by ‘Vogele’ of Germany have been pressed into service for laying the surface of the runway. These machines can lay surface of 200 mm thickness at the rate of 60 m per hour,” the official explained.
