Jaw crusher to pull down Tallah bridge

A machine called jaw crusher will be used to tear down the 57-year-old Tallah bridge to minimise the amount of dust released in the air and the vibration caused by demolition, PWD engineers said.

The government has decided to start pulling down the north Calcutta bridge, which has lost much of its load-bearing capacity and is in danger of collapse, from the first week of January.

“A jaw crusher works like a shark opening its jaws to gobble up concrete and steel,” an engineer said. “The machine produces much less vibration compared with more common crushing machines and releases negligible amount of dust in the air.”
