Apparatus for stringing high tension power lines on a set of towers

An apparatus for stringing high tension power lines on a set of towers, comprising:

• first pulley means (2) mounted generally on the top of each tower (1) for receiving a first cable (T) and a spreader member (3) carrying at least second and third cables (T1, T2);
• rolling guide means (SG1 to SG6) mounted above each crossarm of each tower, guiding cables along the rolling surface of said rolling guide means, generally downwardly from said first pulley means;
• a second set of pulley means (11, 11a) suspended from the insulators of each crossarm for receiving at least one of said second and third cables (T1, T2);
• second guide means (10, 19, 22 to 26) for connecting each of said rolling guide means (7, SG1 to SG6) to each of said second set of pulley means (11, 11a) for guiding cables from said rolling guides into the central sheave of said second set of pulleys;
• wherein said second guide means include reeving wheel means (22 to 26) and "broom"-means (10, 19) consisting of an articulated rod (10) whose upper end is connected to the tip (7') of the crossarm and to the lower end of one of said rolling guide means by means of an interface consisting of said reeving wheel means (22 to 26), whereas a lower end (19) of said articulated rod (10) is hooked to the central sheave (21a) of one of said second set of pulleys beneath said one crossarm;
• wherein said interface includes a rotating reeving wheel (22), said wheel having means (25) for allowing the cables (T2) that slide along the rolling surface of said rolling guide means to pass through the interface and slide between the insulators and the sliding surface of said second guide means.
