WALL LADDER
ASSEMBLY AND DIMENSIONING
LADDER PLACEMENT
The best placement for the ladder is the gable where snow loads cannot damage the ladder and
its fastenings. If you intend to install the ladder to the side of the house, we recommend installing
snow guards on both sides of the ladder.
• Choose the leg length so that the rung distance is a minimum of 200 mm measured from the
nearest protruding part (for example the eaves). The legs can be shortened.
• Top rung ± 100 mm from the eaves
• Lowest rung 1100 ± 100 mm from the ground level or other starting point
Placement of wall legs:
• The topmost wall legs are fastened as close to the eaves as possible
• The lowermost wall legs are fastened halfway between the two
lowest rungs
• Maximum distance between wall legs is 3000 mm
• Use an eaves support every time the wall leg length is 50 cm or more.

WALL LADDER
USAGE, MAINTENANCE
AND GUARANTEE
USAGE
All buildings must offer a passageway to the roof so that all objects, such as
the chimney, battens, roof safety, lead-throughs, and electronic equipment
can be checked and serviced in a safe manner. Orima®wall ladders provi-
de a safe passage to the building’s roof.
Once the ladder’s rise exceeds 8 m, you should equip your ladder with
safety rails or back arcs. The Orima®wall ladders can be used as an at-
tachment point for a lifeline.
The ladder and the fastenings can withstand a minimum vertical point load
of 2.6 kN and a minimum vertical total load of 3.9 kN per every three met-
res. The wall ladder’s hand rail and its fastening can withstand a minimum
0.5 kN horizontal outward force.
MAINTENANCE AND INSPECTION
Yearly maintenance and inspection procedures for Orima®wall ladders:
• Visual checking of general appearance, such as damage on ladder
structures due to snow loads or other strain, damage to paint coatin-
gs, visible corrosion, loose fastenings, and so on.
• Grip and tightness of fastening points, joints, and fastening equip-
ment
• Checking the roof fastenings and lead-throughs for tightness
• Removing excess snow load from the roof as required
• Clearing the ladder of snow, ice, and other dirt
• Touch-up painting of damaged coatings and replacing or repairing
damaged or faulty parts.
