Hanyar Helicopter Don Kawo Tashin Turawa
A hanyar helicopter, tashin turawa na jirgin ruwa da suka fitowa. Farkon tashin turawa suna iya kawo har da kadan da suka fitowa. Farkon tashin turawa suna iya kawo har da kadan da suka fitowa.
Idan ake fitowa tashin turawa, ana iya amfani da helicopter. Helicopters suna iya amfani da su don kawo har da kadan da suka fitowa. Helicopters suna iya amfani da su don kawo har da kadan da suka fitowa.
Helicopter suna iya hover over the line location while the tower is securely guyed. Ground crewmen connect and tighten the tower guys. As soon as the guy wires are adequately tensioned the helicopter disengages and files to the marshaling yard. This method is adopted where the approach is very difficult or to speed up the construction of the transmission line.
Tightening of Nuts and Punching of Threads and Tack Welding of Nuts of Transmission Towers
Duka nuts suna iya tight properly using correct sized spanners. Before tightening it is ensured that filter washers and plates are placed in relevant gaps between members, a bolt of proper size and length are inserted and one spring washer is inserted under each nut.
In the case of step bolts, the spring washer shall be placed under the outer nut. The tightening shall be carried on progressively from the top downwards, care being taken that all bolts at every level are tightened simultaneously. It may be better to employ four persons, each covering one leg and the face to his right.
The threads of bolts shall be projected outside the nuts by one to two threads and shall be punched at three positions on the top inner periphery of the nut and bolt to ensure that the nuts are not loosened in course of time. If during tightening a nut is found to be slipping or running over the bolt threads, the bolt together with the nut shall be changed outright.
Painting of Joints of Transmission Tower
For galvanized towers is coastal or highly polluted areas, the joints shall be painted with zinc paint on all contact surfaces during the course of erection.
Checking the Verticality of Erected Transmission Towers
The finally erected tower shall be truly vertical after erection and no straining is permitted to bring it in alignment. The tolerance limit for vertical shall be one in 360 of the tower height.
