HANDLING AND INSTALLATION
5.1
TRANSPORT AND UNLOADING
WARNING :
: If not carried out with the utmost care, lift unloading, transport and lifting operations
can be dangerous: so keep all the unauthorised people away from the lift; clean, clear and
delimit the installation area; check that the available tools are suitable for use and in good
operating conditions; do not touch any suspended loads, and stay at safety distance; during
transport, suspended loads shall not be more than 20 cm from the floor; thoroughly respect the following
instructions; do not proceed in case of doubts or uncertainty. The lift is shipped packed onto a pallet to make
transportation and handling easier. The packed lift shall be transported with a fork lift having a suitable
capacity. During handling, avoid that the packed lift, the single structures and, above all, the control unit are
subject to impacts or dashes. Packed lift overall dimensions and mass are shown in Figure 13
WARNING : All the following installation, adjustment and testing operations should be carried out
only by qualified and responsible staff operating according to the applicable electric, hydraulic,
pneumatic, mechanic and building safety standards.
DANGER
: The installation, the adjustment and the testing of the lift imply potentially dangerous
operations. Therefore, all the instructions given here below should be carefully read. In case of
doubt, please contact the Manufacturer. The manufacturer disclaims any responsibility in case of
non-compliance with the safety standards and with the accident prevention rules given in this
manual.
DANGER
:
If the lift is installed on a floor slab it is necessary to consider the lift weight plus the
maximum liftable load resting on the lift bearing surfaces using adequate safety coefficients. It is
responsibility of the purchaser to carry out this check at his/her charge.
