Procedure for lifting Derrick pole -Get the approved drawing for tower erected -Do not start before 14 days concerting. -Clit plate fitted in stub. Derrick pole joint in back side of stub Four no guy rope 22mm or 24 mm should be on the top of derrick pole Double pulley should be fixed on top of derrick with the help of 8 ton d-shackle and it should be fixed near the stub. Sling should be fixed with tractor. For lifting derrick pled made a structure (horse type in middle of derrick pole For lifting derrick pole with the support of structure and pulling by tractor. All guy rope supported with two people for balancing derrick pole. All guy rope have required three crow bar and it should be cross design
