WABC<\/a> reports, as the investigation continues into the Tappan Zee Bridge crane collapse, the Eyewitness News Investigators have learned that the crane is the newest high-tech crane now being used on construction projects.<\/div>\n
There are more cranes operating at this bridge site than anywhere in the nation and until Tuesday the huge construction project had just three minor safety violations.<\/div>\n
<\/div>\n
Now it’s the site of a major accident investigation and at the center of it, a cutting-edge, highly computerized crane.<\/div>\n
<\/div>\n
\n

Of the 28 cranes building the massive 3-mile long bridge, one model really stands out: the MLC300<\/a>, a new, ground-breaking, high-tech crane, known for its automated computerized counterweight system that allows for quick set-up and heavy-lifts.<\/p>\n

Its revolutionary qualities were touted in a recent promotional video, with a crane worker saying “Assembly was very easy with the MLC300, put it up and within a day had crane fully assembled.”<\/p>\n

Now this state-of-the-art crane is at the center of an investigation after suddenly collapsing while hammering in bridge pilings.<\/p>\n

“They’re the leaders of the industry,” said crane accident consultant James Pritchett.<\/p>\n

Pritchett says Manitowoc <\/a>of Wisconsin manufacturers the new MLC300. He says they are the best in the crane business.<\/p>\n

“They go through so much quality control dealing with these cranes. I couldn’t ask for a better crane,” he said.<\/p>\n

We’ve learned the crane had been in operation at the bridge for a few months. Pictures from the website Earthcam shows the crane doing piling work just minutes before it collapsed.<\/p>\n

There appears to be no problem. The question is how did this brand new crane with the latest safety technology end up in broken bits of metal.<\/p>\n

“You have to analyze all aspects,” said Pritchett.<\/p>\n

Including looking at whether vibrations from hammering in the pilings possibly damaged the crane or was it a manufacturer defect, experts tell us however, brand new cranes rarely come crashing down on their own.<\/p>\n

“Cranes today lift tremendous loads, high-tech, so dependent on individual operating the crane programming it correctly and run it in accordance with manufacturer specs, the likelihood of an accident is very minimal,” said Pritchett.<\/p>\n

We’ve learned investigators are looking closely at what role, if any, the hydraulic hammering of the bridge piles played in the collapse, specifically whether any weight-overload caused sudden stress on the crane.<\/p>\n

Too early to tell, we’re told that a team of federal safety investigators could take months to determine an exact cause.<\/p>\n<\/div>\n
