would 2 500 ton crawler cranes be able to lift a 854 ton bridge section 80 feet in the air?

Sorry, no I Googled a 2,500 ton crawler crane and it's maximum lift capacity is 550 tons.
“Crane Information > Demag CC2500
Demag CC2500 Crane Chart
The Terex/Demag CC 2500 Lattice Boom Crawler Crane has a 550 ton lifting capacity with a maximum boom length of 275 feet, and up to 551 feet with a luffing fly jib extension.”
There is a chart in every crane cab that will tell you what tonnage the crane can lift and at what radius from the center of rotation of the House/ that is the part of the crane that rotates.
For example the crane in the link can lift 550 tons at 7 meters from the center of rotation of the House.
This is from page 2 of the PDF file, for the Demag CC2500 Crane Chart:
The farther from the center of rotation of the House, the less a crane can lift.
That same crane can only lift 57.5 tons at 22 meters from the center of rotation of the House.

wow. im helpful anybody tried it!! why : the recommendations co-ordinates the strikes of the finished physique. fairly the arms and the ft, so once you're turning your appropriate foot in clockwise path, with the help of drawing 6 jointly with your hand, that's an ANTI-CLOCKWISE circulate, the recommendations then makes the foot circulate anti-clockwise. Thats how suitable GOD made us!!
