Hot Line Ladders are intended for several applications on high voltage hot line works, for they permit the lineman to work in a convenient position and perform line repairs on hard-to-reach places.
All hooks are made of diameter 25.4 mm (1”) steel with surface treatment and are of swivel-type for adaptation to the several positions on the structure.
For increased operational safety, the hooks are provided with steel with surface treatment chain and locking system.
The rungs are made of diameter 32 mm (1.25") Ritzglas® poles, with slidingproof coating.
In addition to the high mechanical strength of the connections between side rails and rungs, the Ladders for Hot Line Work are equipped with reinforcing steel rods close to the ends of the ladders.
Single Ladders with Hooks
The ladders series RH4903-8 through RH4903-12 are built with diam. 38 mm (1.5") Ritzglas® poles and the Ladders series RH4904-8 through RH4904-16 are built with diam. 51 mm (2") Ritzglas® poles, which form the siderails. They are only used for vertical position works.
The ladders (series RH4905-8 through RH4905-20) are built with diam. 64 mm (2.5") Ritzglas® poles, which form the side rails. These ladders are more appropriate for horizontal position works.

One-Siderail Sectional Ladder
Designed to work in a vertical position to allow access to the conductors of electricians on suspension chains de-energized, without the need to be supported by the insulator string, thus avoiding possible accidents by breaking the insulators.
Built with tube diam. 51 mm (2") Ritzglas® how your center siderail and rungs tube Ritzglas® diam. 32 mm (1.25").
All sections are interchangeable, allowing to reach different heights with 3 sections and whose lengths are suitable for transportation.
The top section has unique swiveling hooks on 14" steel and connections between sections are performed with the aid of gloves steel surface treatment and cotter bronze for the perfect lock.
All sections have bag for packing and transportation.
