Ladder with lifeline specification guide

1. Materials

  • Only materials that are not subjected to corrosion can be used. The ladder is made of aluminum alloy profiles, anodized 10 micron, natural mat finishing; fasteners (bolts, rivets and washers) of stainless steel A2-70 DaN/mm2; joint washers, bushes, plugs, etc. in polyamide and elastomer.
  • No protective treatment, painting, or maintenance is required, except when exposed to aggressive environments.
  • No welding is allowed. The rungs are clinched into the uprights. Bolts and rivets are used for all other assembly.
  • The ladder can be polyester powder coated in any RAL color.

2. Installation

  • The ladder is installed vertically.
  • A single type of fixing clamps is used for the attachments of wall fasteners to the ladder uprights. These fixing clamps can be clipped to the ladder uprights at any desired position.
  • The ladder can expand freely within its anchor brackets without deformation or damage to allow for thermal expansion.
  • For lateral access to the ladder, the upper rung is at approximately 1.5m above the upper point of access. For access from the top, widened upright projections can be used, allowing a passageway of at least 62cm. In this case, the upper rung is at level with the access floor.

3. Dimensions

  • The ladder corresponds to standards EN 131 and ISO 14122-4.
  • The ladder is composed of standard elements of 3.36m maximal length, assembled to the desired length. These elements are connected by perforated aluminum sleeves, shifted inside the uprights.
  • Bolts are used for fastening. The uprights are spaced at 400mm, and the rung axes are at 280mm.
  • The ladder uprights have an oblong section of 75mm x 25mm x 2mm with rounded corners. The rungs are round at 37mm with a flattened and grooved anti-slip upper face.

4. Fall arrest system

  • The manufacturer can equip the ladder with a fall arrest system with a fixed lifeline according to standard EN 353-1. The use of the lifeline eliminates the need for a safety cage. The lifeline is based on a fixed aluminum rail and a step-less safety carriage.
