Abstract
Considering the structural size,quality and other parameters of the tower for the transmission line of differ-ent voltage grades including 110 kV~500 kV~1 000 kV,and the process of erecting the tower and the mobile crane and technological features,the paper summarizes the technical parameters for erecting different towers. According to the field operation point group,the crane performance curve and typical duty parameters are described in the paper,with the per-formance curve covering 90.6% of all the working conditions. Considering the landform characteristics of the transmission line works,the paper puts forward the grade ability,turning radius,crane mass,and overall dimension of two mobile cranes for tower erection in mountainous areas and plane areas. The proposed parameters can provide accurate boundary conditions for desining the pattern and functions of the mobile cranes,meeting the demand of erecting the power transmis-sion line tower.关键词
