Nagarkurnool: An ‘autonomous hydraulic powered robot’ equipped with special machinery, has been deployed to accelerate the search operation for seven persons trapped inside the partially collapsed SLBC tunnel here.
The equipment includes a 30 HP capacity liquid ring vaccum pump and a vaccum tank machine, which are helpful in quick removal of soil and other works inside the tunnel, an official statement said.
Instead of manual digging, autonomous hydraulic-powered robo is being used to remove soil with speed. About 620 cubic metres of soil and muck can be shifted out of the tunnel in an hour by using a conveyor belt, it added.
The use of machines with latest technology would help in carrying out the operation efficiently.
State Special Chief Secretary (Disaster Management) Arvind Kumar has been supervising the search operation.
