DUAL AUXILIARY ARM

DUAL AUXILIARY ARM

It is designed for replacement of utility poles, crossarms, or insulators. Like all RITZGLAS® tools it is lightweight and easy to assemble. In normal constructions or eccentric crossarms this tool can be used as a side arm.

The wireholders can be moved to minimize the transposition distance of the conductors from the insulators to this assembly as this tool is sufficiently sized to use as a lift arm using three wire tongs. 

NOTE
When using the dual auxiliary arm (with voltages greater than 15 kV) or when supporting energized conductors in the rain or chance of rain, installing insulators (RM4805-7) to the dual auxiliary arm under the mounting wireholders is recommended to increase flow distance.

Wiping the insulating pole surface with treatment fabric (RM1904) on the dual auxiliary arm pole is recommended when it is installed at night or chance of rain conditions.

The dual auxiliary arm consists of the following tools:
-    01 Ø 64 mm RITZGLAS® pole combined with a saddle 
   for utility pole mounting by a chain binder;
-    03 pcs fork-type wireholder of 25.4 mm (1")
   opening without insulator (RM4805-17);
-    02 wire tong stirrup (RC400-0331);
-    01 dual auxiliary arm "T" with insulator (RC400-0562)

Tools required for these types of assemblies:
SIDE ARM
-    01 wire tong RH4647-12 (A);
-    02 wire tongs RH4646-8 (B);
-    01 saddle with ext. and clamp 64 mm RM4740-18W (C);
-    01 saddle with mounting eye RM4740-15W (E);
-    01 saddle with ext. and 51mm clamp RM4740-17W (F);
-    01 double block RC400-0914 (G);
-    01 clamp for block RM1729-1 (H).

SIMULTANEOUS LIFT OF ASSEMBLY
-    01 wire tong RH4647-12 (A);
-    02 wire tongs RH4646-8 (B);
-    02 saddles with extension and clamp, Ø 64 mm RM4740-18W (C);
-    01 64mm brace strap RM1728-5 (D)

TOOL APPLICATION
-    RE400-0008 (1-1/2” without insulator)  -    RM4805-15 (1” without insulator)
-    RE400-0009 (1-1/2” with insulator)       -    RM4805-17 (1” with insulator)
These wireholders have 25.4 and 38 mm (1” and 1-1/2”) openings and a counterbalanced device that automatically closes with conductor insertion and must be reversed to release the conductor.
These tools, with or without insulator, also have a Ø 64 mm clamp for coupling to the dual auxiliary arm crossarm.
 

-    RC400-0331 (Ø 64 mm) 
An equipment that can be purchased separately as a replacement part or to be added to existing equipment. It is designed as a coupling point for the wire tongs used as braces of the dual auxiliary arm through its clamp. Besides being easy to install, it is made of aluminum alloy.
 

-    RM1728-5
It is used to attach the wire tong (which stands vertically as the mast supporting the dual auxiliary arm) to the wire tong eyes, which act as the braces of the set.
Made of aluminum alloy, the two halves of the strap form one piece, joined by two eye bolts. 
Rated Work Capacity: 454 daN (1000 daN)
 

-    RC400-0562                                    -    FLV00714-2
It is specifically designed for use in the simultaneous lifting arrangement of the lifting assembly.
