VERTICAL MOUNTING AGAINST SCAFFOLDING USING VE FIXING
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 scaffolding, make sure that it is 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 the scaffolding
pulling on a rope attached to the end of the ladder (the person on the scaffolding must wear a safety
harness with fall arrest system).
- Press the whole unit against the scaffolding tubes previously clamped to the scaffolding with couplers.
These tubes must protrude about 1m from the outside of the scaffolding. Use 1 tube per floor, i.e. every
2m
-
Clamp the ladder to the scaffolding with the “VE” fixing clamps, i.e. 2 per tube or scaffolding 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 c
oncerning “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 scaffolding:
-
Bring the ladder sections up to the height of the headboard using the platform.
- 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 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, winding it 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 scaf
folding tubes, using the “VE”
fixing clamps, i.e. 2 “VE” fixing clamps per tube or scaffolding level.
During the installation and anchoring of the hoist to the scaffolding, 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 the
scaffolding, 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.
