DOB tells contractors to lighten load for certain cranes after 4 WTC incident

In the wake of last month’s accident at 4 World Trade Center, the Department of Buildings is asking all companies using that model of crane to limit their loads to 75 percent of the total recommended capacity, DNAinfo reported.

The city wants contractors to limit loads until the investigation into why the cable at the Tishman Construction project suddenly snapped, sending steel beams careening 40 stories onto a flatbed truck, is concluded.

Bethany Klein, vice president of structural engineering at Tishman, revealed the new restriction at a Community Board 1 meeting yesterday evening, DNAinfo said, saying her company had received a letter from the DOB, as had other contractors operating TG-1900 cranes.
