The site-clearing operation at the Metro accident site near Zamrudpur proved tricky for the DMRC on Monday. According to the DMRC officials,the congested environment at the accident site is adding to the delay in clearing debris.
The officials claim that the entire process of removing debris will take around six to seven days.
The clearing work suffered another set back today afternoon as one of the cranes involved in lifting the collapsed launching girder crashed due to technical fault. This led to another crane snapping,while the third toppled over.
According to officials,around noon four cranes were involved in lifting the 200-tonne collapsed launching girder,when the boom of a high-capacity crane,weighing 250-tonne,snapped. Consequently the extra weight came on to the booms of the adjoining cranes,which led to a 350-tonne crane snapping and another 250-tonne crane toppling over. The fourth crane (of 400-tonne),however,remained,undamaged.

Though five workers suffered minor injuries,the crane operators of all three damaged cranes were unhurt as they jumped out of the cranes in time.
The clearing operation resumed later in the afternoon when six new cranes were engaged at the site. These included: three 150-tonne cranes one each of 100 tonne,250 tonne and 350 tonne.
Around 80 percent of the damaged launching girder has fallen on the ground and the remaining portion is still on the concrete span. The launcher is now being cut into pieces with the help of gas cutters, said Anuj Dayal,spokesperson,DMRC.
The methodology to dismantle the girder between pier number 66 and 67 is being worked out by our engineers, Dayal added.
