Working Platforms (Aluminium Structures)
Suspension Ladders
These ladders are designed to be used in hanging position at the tower-cross arms for performing works, for instance at the insulator chains. They can be used also as anchoring ladders if supplied with the optional foldable conductor hook or tower- and conductor hook (SLA-00-02 or SLA-00-03). If supplied with the optional available anti-fall system (SLA-00-01) the ladder is supplied with a guide rail on the left side.
The tower hook is made of galvanized steel and equipped with a safety chain to prevent accidental fall down of the ladder. The ladder itself is a welded structure of first grade extruded aluminum pipes. The rungs are corrugated for slip protection. The working load in hanging position is 3 KN. If used as anchoring ladder (with optional SLA-00-02 or SLA-00-03) the maximum allowable working load is 1 KN.
