The modular ladder is used for ascent/descent and work at height on wooden or concrete poles (with round or rectangular section).
The modular ladder can be used by a single person, only in the vertical position, fastened to the pole.
The modular ladder for poles consists of the following elements:
· Base section (length 1,5 m / 5 rungs)
· Multiple intermediate sections (maximum 10 sections with length 1,5 m / 5 rungs, one section with length 0,9 m / 3 rungs)
· Top section (length 1,3 m / 5 rungs)
· Work platform (optional)
The base section is provided with two profiled support elements that provide a constant distance between the ladder and the pole.
The other sections are provided at their upper part with a profiled support element.
The base section is fastened by using two special devices (consisting of an anchoring strap, a special ratchet device and a carabiner) and the upper sections are fastened to the pole with one special device.
The rails of the base section have rubber anti-slip caps.
Rails and rungs of the sections are made of tubular aluminium profiles with superior mechanical properties, and the support assembly (consisting of the guiding bushings and profiled support elements) are made of steel, assembled by welding and protected against corrosion by zinc coating.
With regard to the base and intermediate sections, the highest rung and anchoring straps attached to the rails are painted in red, in order to warn the operator with regard to the positioning of a junction between two sections:
– When climbing up, the operator must not step over the red rung of the lower section until the upper section is assembled and completely fastened to the pole;
– When climbing down, the operator must not start the disassembly of the upper section prior to stepping on or below the red rung of the lower section.
The special ratchet device of the anchoring strap and the carabiner are made of steel and zinc-coated against corrosion.
Anchoring straps are manufactured from polyamide or polyester fibres.
The work platform is a welded element, made exclusively from aluminium alloy, provided with a profiled element which can be attached at any rung.
The ladder does not have any safety systems to prevent the worker from falling, the worker must use during work on the ladder adequate fall protection devices (system consisting of a hook or another anchoring device + flexible rope + sliding fall arrester + safety harness).
Benefits: light, short sections, easy to transport.
