Suspended ladders are technical equipment recommended for works on HV overhead line poles of metallic construction (lattice towers), for interventions on suspension insulator strings and on the conductor suspension clamps.
Suspended ladders are used exclusively in vertical position, by hanging them on the metallic cross-arms of the lattice towers. They are made of aluminium profiles and are provided at one end with two steel hooks fitted with safety chains against accidental detachment.
On request, the ladders can be provided with steel hooks with an opening of up to 400 mm.
The ladders are provided on one (models 011/A…) or on both stiles (models 011/B…) with “T” profiles acting as support elements for the sliding of the guided type fall arresters made according to EN 353-1. The guided type fall arresters can be replaced. Suspended ladders are made in several versions (of one module or of two modules) and in several sizes (on request), so that a wide range of works can be performed by using them.
The ladders can be used by one worker (models 011/A…) or by two workers (models 011/B…).
