Block:   LTM 1400-7.1 (Construction)

Which option of the location of the control knob in your opinion is the correct 1 or 2? http: ipic.su/img/img7/fs/00.1678356665.png

Cfytr, your files are excellent but the "round blue grip" for the boom and jib alignement at the angle should be exactly placed at the center of the upper pulleys for the possibility of placing the crane hook at an exact radius to be « in the diagram ». Eventually see my AutoCAD file : LTM-1090-4.2-PJH.dwg that is an update of yours.
