Suspension Ladders
These ladders are designed to be used in a hanging position at the tower cross-arms for performing tasks, for instance at the insulator chains. They are also used 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 falls off the ladder. The ladder itself is a welded structure of first-grade extruded aluminium pipes. The rungs are corrugated for slip protection. The working load in the hanging position is 3 KN. If used as an anchoring ladder (with optional SLA-00-02 or SLA-00-03) the maximum allowable working load is 1KN.
Different dimensions are available upon request.
