Ensuring ease of operation

The portable air compressors of Atlas Copco, deployed at the metro project near the famous Siddhivinayak Temple, contribute to ease traffic woes in Mumbai.
Atlas Copco's portable air compressors have been applied for the first underground metro line in Mumbai, and they are not only under the supervision of Mumbai Metro Rail Corporation (MMRCL) but also under the watchful eyes of Lord Ganesha, as part of the metro line runs in front of the famous Siddhivinayak Temple. The Line 3 of Mumbai MetroĆ» also referred to as the Colaba-Bandra-SEEPZ line- is a 33.5 km-long line that will connect Cuffe Parade business district in the extreme south of the city to SEEPZ in the north-central, with 26 underground and one at-grade station. The cost of this corridor is estimated at Rs 23,136 crore ($3.4 billion). Line 3 is expected to reduce road traffic congestion, besides reducing load on the Western Line between Bandra and Churchgate. Powerful products powering applications two of Atlas Copco's key contracting companies are using its products in the project. While Kasturi Projects is doing shotcreting using Atlas Copco XA 316 compressors, contractor Indigo Infraprojects is undertaking specialised applications such as rock bolting and slope stabilisation with Atlas Copco XAT 266 compressors.

Experiences the might of XA316
Atlas Copco team convinced Kasturi Projects, a sub-contractor for the Line 3 Siddhivinayak Temple project, through a live demo that Atlas Copco XA 316 compressor with a capacity of 100 PSI/650 CFM would be the ideal model for the application of wet shotcreting. XA316 covers a bigger area of shotcreting work in lesser time as compared to the earlier brand of compressor. The contractor experienced a lesser rebound due to continuous flow of air at the desired pressure, which resulted in savings of raw material (shotcrete).

12 XAT 266 deployed by Indigo Infraprojects
The company's long-standing customer from Delhi, Indigo Infraprojects, in view of their trust and good experience with Atlas Copco's portable air compressors, has deployed 12 compressors - XAT266- in many key sites of the Mumbai Metro station construction, such as in the city's domestic and international airports, Cuffe Parade station and at the Siddhivinayak Temple. Indigo Infraprojects, a specialist in soil stabilisation, has been able to achieve deeper drilling depths of 33 m at faster speeds with Atlas Copco XAT 266 in tough applications such as anchoring, rock bolting, soil nails, vertical drilling, grouting and shotcreting. Leading the project with its strong fleet of Atlas Copco compressors, the contractor is focused on meeting the deadlines. Atlas Copco will continue to bring in new technologies and more energy-efficient solutions for its customers for use in high profile infrastructure projects, which will transform the urban map of India.
