For what reason was the utilization of U-supports trying for Delhi Metro?

• The establishment of U-braces was finished with the assistance of two cranes having a limit 350/400T which were set at every wharf area, in the prior periods of development.

• The U-braces were moved at every dock area with the help of a long trailer with an inexact length of 42 meters. This interaction was trying for the metro experts in the clogged metropolitan spaces of the public capital.

• This is on the grounds that the situating of the hefty limit cranes consume a great deal of room. Besides, moving the U-supports of 28 meters long with long trailers was additionally troublesome as the streets in the public capital locale for the most part observer weighty traffic volumes.

• These constraints would restrain the utilization of U-supports in development exercises for Delhi Metro, despite the fact that U-braces are the most appropriate designs for viaducts as far as cost and time.

How is the new innovation of ‘Launcher with Transporter’ – accommodating for development?

• The new launcher with carrier is completely electric with a higher yield, contrasted with the customary launchers or cranes. The carrier conveys the U-support from one assigned point and continues onward the rails laid over the raised U-braces, to add more supports from the taking care of highlight the launcher.

• As an aftereffect of this cycle, the U-supports are to be shipped on the trailer simply up to the taking care of point distinguished at a reasonable area and not for the whole length of the track. This outcomes in a considerably less utilization of room.

• The new launcher is 62 meter long having a complete load of 230T, as per Delhi Metro. It can arrange slopes up to four percent and 200 meter span bends. While, the carrier which moves the brace is 41.75 meter long having a complete load of 35T, which can go with a speed of three km each hour at no heap and at two km each hour at full burden.

• The yield of the new innovation is higher when contrasted with the regular strategy for the starting of U-braces. Overall, four-to-six U-braces each day can be raised with the new launcher, while, with the ordinary strategy, around two U-supports should be possible in clogged spaces of Delhi or different regions in the public capital area.

• Moreover, the erection work of U-braces with the regular cranes must be finished during night hours as it requires the hindering of streets to situate the cranes. Though, with the new launcher, the braces are shipped with the carrier over the raised viaduct with no interface with the street from a solitary distinguished taking care of point.

The launcher was made functional on Monday, July 5, for the development of a 9.5 kilometer long viaduct from Mukarba Chowk to Ashok Vihar covering four metro stations – Majlis Park, Bhalswa, Azadpur, and Ashok Vihar, and an association with the warehouse from Majlis Park.
