I INSTALLATION INSTRUCTIONS FOR THE SAFERAIL FALL ARREST SYSTEM
The SafeRail fall arrest system and the SafeRail Carriage-safety carriage ensure safe ascent and descent
through its built-in fall arrest feature. The system is designed to be used on vertical structures.
Using the system for any other purposes than those specified by the manufacturer is forbidden.
If the product is sold outside of Finland, the reseller must deliver the installation and user instructions of the
SafeRail-fall arrest system in the language of the country in question.
1. BEFORE INSTALLATION
Read the installation instructions carefully and ensure that you have the appropriate tools and safety
equipment required available for the installation. Also make sure that the necessary preparations and work
safety measures have been carried out before you begin the installation.
2. INSTALLATION OF THE SAFERAIL LADDERS –SINGLE STEP, TWIN STEP, AND
HANDRAIL LADDER MODELS
Each SafeRail ladder model is based on the Vertical SafeRail MM 101 (safety rail).
2.1 FORBIDDEN METHOD OF INSTALLATION
•It is strictly forbidden to install the SafeRail ladders at a negative angle of climb.
2.2 INSTALLATION DIRECTION
•The installation must always begin at the top, proceeding down.
•The topmost SafeRail ladder section must consist of a complete element (3000 mm or 5700 mm).
Both ends of the ladder element must be equipped with factory-prepared holes.

2.3 FASTENERS USED FOR INSTALLATION
•The SafeRail ladder elements Single Step Ladder MM 111 and Twin Step Ladder MM 112 are
attached to the chosen structure using fasteners that are based on the SafeRail Clamp-rail fastener
MM 211. These are MM 221- MM 263. The SafeRail ladder elements with handrails, Handrail Ladder
MM 121 and MM 122 are attached to the chosen structure using fasteners MM 271 –MM 273.
•When installing the fasteners follow the instructions given for installing SafeRail Clamp MM 211 on
page 7 section 4.1.
2.4 FIXING DISTANCE BETWEEN FASTENERS
•The maximum fixing distance between the fasteners for SafeRail ladders MM 111, MM 112, MM
113, and MM 121 is 2,500 mm.
•However, the maximum fixing distance between the two topmost fasteners is 1000 mm.
•As the fasteners cannot be placed level with the steps of the SafeRail ladder, the fixing distance
between the fasteners must be divisible by 300 mm, for example 1500, 1800, or 2100 mm.
•For the Handrail Ladder MM 122 with supporting handrails, the maximum recommended fixing
distance between the fasteners is 2900 mm. This requires the Handrail Ladder MM 122 to be
attached by the handrails (using Handrail Ladder Fastener MM 271–273, for example). A section of
the ladder amounting to a maximum of 1500 mm may be left unsupported at the bottom of the
Handrail Ladder MM 122.
2.5 JOINING OF SAFERAIL LADDER ELEMENTS
•The SafeRail Joint-extension piece MM 201 is attached using the holes at the ends of the SafeRail
ladder element.
2.6 GROUND CLEARANCE
