In day of old whatever were to be made needed of physical labor and so, workers had to work hard both physically and mentally. But at present because of making ultramodern machine workers do not have to do life-exhausting hard work. Here in this raw footage we could see a new barrier transfer machine. 

Some closeups of the Barrier Transfer Machine (BTM) repositioning the new Moveable Median Barrier (MMB) on the Golden Gate Bridge at the tail end of its. It started at the northern (Marin) end and this video is of it reaching the end of its run at the end, near the toll plaza. The new Moveable Median Barrier (MMB) system is about 13,340 feet of 12-inch wide and 32-inch high steel clad units filled with high density concrete pinned together to form a semi-rigid median barrier.

There are two barrier transfer machines, aka “zipper” trucks. This replaces, and is a vast improvement over, the old yellow plastic pylon divider system, which you can see still in partial use here to block off some lanes at the toll plaza. Thus, guys if you like this footage then you can share this footage among your friends, family, Facebook and twitter.
