Three-section aluminium ladder 3×12 – 8.4 m

The 3×12 odel is designed for situations where standard ladders end. The three-part extension system allows you to operate at heights that normally require scaffolding, but with incomparably higher mobility. It is a working tool designed for intensive use in industrial hall maintenance, roof repairs and assembly work on the facades of high-rise buildings .

Maximum length and working range

The assembly consists of three segments , each with 12 rungs . When all parts are fully extended , you reach a working height of approximately 8.4 meters . This variability allows you to work effectively in hard-to-reach places without the need to rent lifting equipment, which directly speeds up the construction or service process.

Stabilizing structural elements

Safety when working at a height of almost eight meters is ensured by the graduated width of the profiles. The lower part is 44 cm wide, the middle part is 38 cm wide and the upper part is 31 cm wide. This conical layout ensures the rigidity of the entire ladder and minimizes its lateral deflections. The wide base ensures a firm support in the ground, which is essential for stability under maximum load.

Durability and material handling

The aluminum used combines mechanical strength with low weight . The material is naturally resistant to oxidation and corrosion, so the ladder can withstand long-term use in rain, snow or dust on construction sites. Despite the overall length when unfolded, the ladder remains relatively compact in the transport position, which allows transport on commercial vehicles or storage in workshops with limited space.

Field use areas

• Complete service and repairs of roofs and gutter systems.
• Installation of solar panels and lightning rods.
• Maintenance of lighting and technical wiring in high-rise buildings.
• Facade work and installation of outdoor air conditioning units.
• Technical interventions where speed of deployment and high reach are the priority.

Main technical advantages

• The working height of 8.4 m covers the needs of most two-story buildings.
• Three independent parts allow flexible adaptation to the length of the terrain.
• The stable width of the parts (31/38/44 cm) eliminates the feeling of uncertainty when climbing.
• The aluminum construction requires no special maintenance and is ready for everyday professional use.
