The Tower Crane consists of three parts: tower, rear boom and front boom. The tower has a #4 Beam by #4 Beam
cross section, uses #4 and #6 Beams for the vertical members, and #5 Beams for the cross braces. The rear boom is
a #3 Beam in width and the front boom is a #2 Beam in width. Flexible beams are used when there are no more #5
or #3 Beams.
Put a Collet on each side of the Pulley to keep it in place on the front Long Axle. Make sure that the front Full
Round Connectors are oriented so that the “fin” is vertical.
