Concrete beam collapses at monorail site in Parel

The contractors have already finished launching beams for the 8.3-km stretch,which constitutes the first phase of the monorail from Chembur to Wadala and have completed more than 40 percent of the launching activity for the 11.3-km stretch,the second phase from Wadala to Jacob Circle.

Thursday’s mishap took place between the proposed Naigaon and Ambedkar Nagar monorail stations on the second phase.

As per the report,the beam was being launched using two cranes — a hydraulic crane and a lattice boom. “As it was being lifted,the wire rope of the hydraulic crane got entangled with the metallic structure on the pier. The crane operator continued to lift the beam by winding the rope. The rope snapped and one end of the beam rested on the body of the hydraulic crane,while the other end of the beam was held by the lattice boom crane,” the preliminary report said.

Due to heavy rains,the supervisor and the signalman failed to notice the wire rope entangled with the metallic structure,the report added.

Traffic was diverted and the road was reopened for motorists around noon after the beam was removed.

This is the second accident involving the alignment and launching of the guideway beams on the Chembur-Jacob Circle monorail since construction began in 2008.
