Lattice girder supporting frame having straight brace parts

A bracing element for a lattice girder supporting frame having upper and lower boom members, comprising:

• two brace parts angled relative to each other, wherein one end of each of said brace parts has a curved part and the other end of each of said brace parts is straight, the other end of each of said brace parts adapted to be connected to the lower boom members without bending;
• a straight brace part connecting said brace parts to each other at said curved parts so as to form a truss brace, wherein said straight brace part extends parallel to the upper and lower boom members;
• wherein two truss braces are connected to each other via cross-ties so as to form the bracing element, wherein said cross-ties are fixedly secured by a weld to said truss braces, and wherein said cross-ties are adaptable to contact the lower boom members.

A truss brace of a bracing element for a lattice supporting frame, comprising:

• two straight brace parts, each of said two straight brace parts including a first end having a curved portion and a second end having a straight portion;
• and
• a straight bridge piece connecting said first ends of said two straight brace parts so that said two straight brace parts are disposed at an angle with respect to each other.
