6 COMMISSIONING
6.1 General warnings
The following chapters are the core of the manual, and contain the actual operating
instructions on how to install, operate and maintain the Lever chain hoist.
Proper machine installation and commissioning is extremely important and constitutes a
serious risk to the safety of people exposed at this stage or with subsequent use of the
machine if poorly executed.
6.2 Installation
The
Lever chain hoist
must be mounted on a suitable
support
structure,
with
adequate
resistance
characteristics. This structure must, in fact, be able to
support the
weight of the hoist plus the maximum
nominal loading capacity
(which is more than 1500 kg
in the case of art. 0237/15).
The following can be used in this regard:
beams and/or similar fixed structures;
parts of other lifting devices such as jib cranes,
overhead cranes, etc.;
Hook the upper hook, for attaching the hoist to the
support structure to the structure itself; after which
prepare the chains so that they are loose and fully
stretched out (no twisting).
Figure 7 – Hoist installation.
Hoist attachment hook
Check the connection of the hoist attachment hook and the perfect closing of the safety latch.
6.3 Preliminary testing
Errore. Il segnalibro non è definito.
Before using the machine it is necessary and essential to carry out preliminary testing in its
place of use.
The test includes:
a general visual inspection of the machine to make sure there are no damaged and/or
worn parts on the structure itself, chains, hooks, etc.;
the proper arrangement of the chains (they should not be rolled or twisted);
a verification that the machine functions properly making it perform a few complete
cycles (the entire stroke of the lifting chain) of lifting/lowering unladen (i.e. without a
load);
an operating test of the safety brake, making it perform a few complete descent cycles
with small loads (max 10 kg).
