VERTICAL INSTALLATION AGAINST THE FAÇADE OF A BUILDING
USING CLAMPS
- Prepare the base of the unit, making sure that the floor surface is level. If the floor is wet and loose,
install the unit onto boards.
- Lay the base ladder flat (rungs towards the ground) and then insert the 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.
- Before installing the hoist on the façade, make sure that the anchors (balcony clamps, enclosure
clamps, supports for fixing to the building, etc.) are correctly fixed to the building and that the building
structure can withstand the forces generated by the hoist during its use.
- Up to 6 or 8 m of ladder length, hoist the unit with 1 person on the ground and 1 other on a higher floor
of the building pulling on a rope attached to the end of the ladder (the person on the upper floor of the
building must wear a safety harness with fall arrest system).
- Support the unit against the anchors previously installed on the balconies or windows. Set up 1 anchor
per floor, i.e. approximately every 2 to 3 metres.
- Clamp the ladder to the anchoring with the fixing clamps, i.e. 2 fixing clamps per anchoring or floor
level.
- The base of the structure of the hoist must be solid and durable.
- Secure the base ladder so that the ladder cannot slip to the ground. The ladder shoes must be
anchored to the ground using dowels or fixing plugs adapted to the type of support. The dowels or fixing
plugs must have a minimum diameter of 12 mm.
- Insert the headboard into the end of the ladders and lock it with 2 quick bolts.
- Set up the winch following all the instructions in the previous paragraphs concerning "Installation of
winches...".
-
Install the lifting cable, observing all the instructions in the previous paragraphs concerning “Installation
of the lifting cable", and passing the cable over the headboard pulley (from right to left), then back down
to under the trolley. It is not necessary to dismantle the pulley to install the cable, but be very careful not
to get your fingers caught, cut or crushed!
- Then attach the rope to the trolley and tighten it, observing all the instructions in the previous
paragraphs concerning "Installation of the lifting cable..." The hoist is now ready to be used for the
assembly of the next ladders.
The following ladders can be assembled from the upper floors of the building:
-
Bring the ladder sections up to the height of the headboard using the platform and unload them.
- Lower the moving equipment to the lower stop and then take up enough slack in the lifting rope so that
the headboard can be removed without removing the lifting cable.
- When the headboard is removed, the new ladder elements must be inserted one after the other and
locked with the quick bolts.
- Then unwind enough of the lifting cable so that the headboard can be reattached above the newly
assembled ladders.
- Retract the lifting cable, ensure that it is wound correctly onto the winch drum.
- The trolley can be raised and lowered again.
- Proceed as above for the installation of the following ladders.
- As the ladders progress, clamp them against the previously installed anchors, using the fixing clamps,
i.e. 2 fixing clamps per anchor or floor level.
During the installation and anchoring of the hoist to the building, the operators are of course obliged to
comply with all safety instructions in order to preserve the safety of the personnel, the environment and the
material.
The personnel who will perform the installation and the anchoring of the ladders from a balcony or
a window, will have to be equipped with a safety harness with a fall arrest system and a helmet.
We also remind you that it is strictly forbidden to use the hoist for access and transport of personnel.
