The Trolley Pole Set is used for displacement of the string of suspension insulators to the structure.

Made of Ritzglas® pole and metallic aluminum and steel parts, the trolley pole can be horizontally fastened under the tower arm using tower type wire tong saddles.

The fork suspension tool attachment (RH4723-2), slotted type, for insulators from diam. 267 mm (10.5") through 273 mm (1 ft) properly bolts to the end of the diam. 64 mm (2.5 ft) Trolley Pole. Together with the single trolley wheel (RH4723-4) or the tandem trolley wheel (RC400-0152) used on extremely long or heavy insulator strings, these tools form the complete set of the Trolley Pole Suspension Insulator Tools.

The slotted suspension tool attachment fixed to the pole can be fitted under the top insulator of the string for removal and horizontal displacement for maintenance purposes and return to the original position.

 COMPONENTS

NOTE

SUSPENSION STRING - The slotted tool attachment, tandem trolley wheel and trolley pole set has been designed for a maximum work load of 400 daN (880 lb), but the following procedures must be observed during its application:

1.  Always use the tandem trolley wheel with diameter 64 mm (2.5") pole clamp (RC400-0152)

2. We recommend the 64mm dia. trolley sticks RH4721-112 for above load.

3. The maximum distance between the fixing points of the trolley pole and the structure is 2 m (6.5 ft), in order to avoid excessive bending of the pole

4. The attachment of the diam. 64 mm (2.5") pole clamp of the tandem trolley wheel to the slotted tool attachment and pole assembly, must provide maximum clearance of 500 mm (1.65 ft) from the tool attachment center.
