A flock of cranes (of the mechanical kind)

For those who work in onshore and offshore rigs, ports, tall building construction sites, and generally in any structural and construction engineering projects, cranes might be an everyday occurence. In Chennai, there has recently been a lot of construction activities and cranes are being used a lot. These may not be massive projects compared to those in the USA, China, or elsewhere – but this does seem interesting to those who have never seen big machines before.

Here are some photographs of different cranes:

  • A hammer-head tower crane at work on a building construction site
  • A crawler-mounted Latticework Boom Crane with a clamp shell bucket for dredging out the sediment at a desalination plant construction site near Muthukadu on ECR at Chennai
  • A wheel-mounted standard crane with rotating operator’s cabin that is used when construction has to take place within a limited area. These cranes are used for building the “Chennai Metro Rail” and the construction has to take place amid heavy traffic. I did not find enough safety mechanisms but the city is so populous and there is hardly any alternative travel route for people
  • A modified overhead gantry (hoist) on a beam to move each concrete block into place on the overhead road bridge. The roads seem so full what with a large storage of scaffoldings, hooks, sockets, shackles, wire ropes, chains, slings and hitches, rods, concrete and other equipment close to the places of construction

I included this post in this blog as there is some geo-engineering involved in the form of soil-testing, feature mapping, dredging, drilling, etc … and more so because I get excited by cranes 😉

Hope the cranes can lift us to a less-congested future.
