<p>PURPOSE:To provide a pulley for supporting a cable lifting wire used for fastening work of transmission line extending work in which the hoisting of the wire by power can be also performed. CONSTITUTION:A driving means 3 is remotely connected to a pulley body 2 through a flexible shaft 4. Consequently, the pulley body is substantially separated from the driving means, it is avoided that the pulley body is affected by the weight of the driving means, and the pulley body can be used substantially under almost the same condition as a general pulley while it has wire hoisting performance.</p> |
