Lay the base ladder flat (rungs towards the ground) and then insert the accessory trolley into the ladder so
that the profile is clamped between the rollers.
In order to fully insert the trolley into the ladder, the parachute cams must be unlocked by turning the shaft.
The trolley must be oriented so that the parachute cams are at the top when the ladder is hoisted.
Assemble the ladders and lock them with quick release bolts. The assembly on the ground can be done
parallel or perpendicular to the façade of the building depending on the available space.
Insert the quick bolts through the rectangular openings in the ladders, then rotate them one
quarter of a turn to secure the screw head, then tighten by turning the clamping ring in a
clockwise direction.
