Balcony Ladder Specification Guide

Materials

The telescopic hatch system ladders are made of cathodic E/D coated steel with a thickness of 20µm. This coating process assures high durability in a variety of climates. The telescopic hatch systems ladders are 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%).

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 using bolts that are already present in the frame.

The frame of the hatch system ladder  is installed in the floor of the balcony to reduce visual impact. It can be casted into a hole or fitted onto a metal structure. It is anchored using lateral angle pieces provided with the ladder.

  • Interior = 60cm x 68cm
  • Exterior = 65cm x 73cm
  • Height = 20cm

The balcony ladder is available from 5 to 11 rungs, serving heights of 1.7m to 3.7m per ladder.

Child Safety Lock

The frame of the hatch system ladder  is equipped with a child safety lock to reduce the risk of use of the ladder by children. When opening frame from the top, a safety lever is pushed to unlock the ladder.

Usage

When the frame is opened, the ladder can be unlocked to telescope down until it reaches full length.

Closing is exclusively from the top. Opening is by default from the top.

The hatch system ladder can be fitted with a double acting opening frame that allows opening from the bottom as well as from the top
