Ladder integrated to balcony - Specification guide

1. Materials

  • The telescopic Hatch System Ladders are manufactured of cathodic E/D coated steel (thickness 20µm). This coating process assures high durability in a variety of climates.
  • The telescopic Hatch systems ladders have been tested for water resistance (over 500 hours at 40°C), humidity (over 500 hours at 50° and RH 98%) and salt water spray (over 800 hours (JIS Z 2371 35°C – 5%)).

2. Installation

  • The Hatch System Ladder is composed of a frame and a telescopic ladder. The frame has a top and bottom cover that can be opened. The ladder is fitted inside the frame. This is to be done using the bolts that are already present in the frame.
  • The frame of the Hatch System Ladder is installed directly in the floor of the balcony to reduce the visual impact of the solution. It can be casted directly into a hole or fitted onto a metal structure. It is anchored using lateral angle pieces provided with the ladder.

3. Dimensions

  • Dimensions of the frame are:
    • interior = 60cm x 68cm (1' 12" x 2' 3"),
    • exterior = 65cm x 73cm (2' 2" x 2' 5"),
    • height = 20cm (8").
  • The balcony ladder is available from 5 to 11 rungs, serving heights of 1.7m (5' 10") to 3.7m (12' 0") per ladder.

4. Child Safety Lock

  • The frame of the Hatch System Ladder is equipped with a Child Safety lock in order to reduce the risk of unwanted use of the ladder by children. When opening the frame from the top, a safety lever needs to be pushed in order to unlock the ladder.

5. Usage

  • When the frame is opened the ladder can be unlocked so that it will telescope down until it reaches its full length.
  • Closing is done exclusively from the top. Opening is done by default from the top.
