    Sorry, no I Googled a 2,500 ton crawler crane and it's maximum lift capacity is 550 tons.

    http://www.bigge.com/Demag-CC2500.html

    “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:

    http://www.bigge.com/crane-charts/crawler-crane-ch...

    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!!
