TROLLEY POLE
It is used to transport the suspension insulator string to the structure.
Constructed with RITZGLAS® tubing and aluminum and steel metal parts, the trolley pole can be installed horizontally under the tower crossarm through the metal structure saddle.
The scoop (RH4723-2), with a socket for Ø 267 to 273 mm insulators, is properly installed on a Ø 64 mm or 76 mm pole, with swivel eye and through the single sheave or double sheave. The latter is used in large strings or heavy insulators, thus forming the trolley pole assembly.
The scoop coupled to the stick is mounted under the first top insulator of the string for removal and horizontal movement for maintenance, and to return it to the original position.

NOTE
SUSPENSION STRING - The fork suspension tool, tandem trolley and trolley pole set is for a rated load of up to 400 daN (880 lb), however the following procedures should be observed in its application:
1. Always use tandem pulleys with 64 mm clamp (RC400-0152).
2. The recommended trolley pole size for this load is Ø 64 mm
(RH4721-112).
3. The maximum distance between the trolley pole attachment points on the structure to prevent excessive bending is 2 m.
4. The coupling of the Ø 64 mm Tandem Trolley clamp to the fork suspension tool must be within 500 mm of the scoop center.
