CONFIGURATION OF THE MODULE
A sticker on the modules and
bases indicates the orientation
of the stair tower depending on
the height required and gives
instructions for lifting, anchoring
and transport.
The Module:
All the module’s faces are secured by
swivel guardrails.
The triangular steps
reaching into the corners
(0.51 x 1.00 m) act as
landings for resting and
allowing users to pass.

USE OF THE ERECTION GUARDRAIL
WARNING:
The erection guardrail must not be used as a substitute for the barrier gate.
WARNING:
During transport, reset the erection guardrail horizontally to keep to a road legal height.

WARNING:
Check that the ground on which the staircase Escalib is to be erected is able to withstand the load.
WARNING:
Comply with the general rules for handling and stability.
1 - The base must be oriented
according to the height of the floor
which needs to be accesed.
Start the installation 8 cm away from
the wall to facilitate pivoting of the
guardrails at the access level.
Level the base.
2 - Access inside the module is
available for attaching the sling
to the center ring, for putting the
guardrails in closed position and
putting the erection rails in hori-
zontal position.
3- Fitting the module to the base.

Repeat steps 2, 4 and 5 if needed
while anchoring the Escalib as
the height is increased.
REQUIREMENTS:
> Fit new anchorages as
new modules are added.
> Dismantle in the reverse
order of assembly.

WARNING:
Check that the ground on which the staircase Escalib is to be erected is able to withstand the load.
WARNING:
Comply with the general rules for handling and stability.

6 - With the sling still tied, fit the
modules to the base with M24
screws.
7- At the access
levels, the guardrails
are positioned so as
to privilege access by
the main face A (face
names shown on the

a vertical position and locked onto
the stairs above . Before untying
the slings, anchor the Escalib.
The last step
used should
ideally be
placed 21 cm
lower than the
floor being
serviced.
REQUIREMENTS:
> Remove the anchorages as the
Escalib is beeing dismantled.
> Dismantle in the reverse order of
assembly.

To make it easier to size the anchor points and ground bearing for the Escalib, the ground load
calculations and the forces at the anchor points are given for the various configurations.
If “d” is greater than 20 cm,
wind bracing may be required to
reinforce the anchor system.
Configuration 2 requires special
calculations.
For a given direction, forces from
both ways must be taken into
account.

corresponding to a wind speed of 107 km/h.
In configuration I, the Escalib is anchored every 3 modules.
Each anchors must withstand the following stresses:
- shearing : V = 300 daN,
- pullout : T = 200 daN.

Transport:
For transport, Escalib must be loaded as illustrated in the figure. They must be firmly strapped in place to
avoid any risk of becoming dislodged during transport.
Each Escalib module is placed upright (1.68 x 1.68 m overall size). The bases can be placed on their
side, alongside the modules, if necessary.
The modules can be transported with barrier gates fitted.

- 12 m flatbed: 7 modules and 7 bases.
- 13.50 m flatbed: 8 modules and 8 bases
BEWARE DURING TRANSPORT:
In order to keep the
dimensions road legal, do
not stack the module on the
base and reset the erection
guardrail to horizontal.

WARNING:
- For transportation use a flatbed semi-trailer.
- For stability reasons, do not stack the bases during transport.
- Attach straps to the stringers, not the guardrails.
