4. Anchoring the hoist - installation
GB
Check that the fixed attachment point is sufficiently
strong for the force to be applied.
If the hoist is to be mounted in a location which is
dangerous for the operator, the safety precautions
required by the applicable work regulations must
be taken to eliminate any safety hazards during the
operation. In this case, it may be preferable to install the
lifting wire rope in the hoist before starting the fastening
operation (see section 5).
The hoist can be used suspended or bearing on its
base.
4.1. Anchoring the hoist in the suspended
position
This is the easiest and most commonly used installation
method. The unit must only be secured by its hook
(except 4.2 below) and never by its handle. It is
prohibited to secure the wire rope hook to the fixed
point and to operate the hoist as it moves along the wire
rope (Fig. 3: mandatory installation, Fig. 4: prohibited
installation).
The hoist hook must be placed in the fixed point
fastening device so that the fastening device is fully
engaged on the hook. The safety flap on the hook
must close completely. If any interference appears
in the swivel part of the hoist hook with the fastening
component, a sling of appropriate capacity should be
used.
4.2. Anchoring the hoist bearing on its
base
This type of installation requires special precautions:
1. The bearing surface on which the hoist is placed
must be flat and horizontal.
2. This surface must have a hole for passage of
the two wire rope strands. The configuration
and dimensions of the hole are given in figure
24 showing the bearing face of the hoist and its
position on the hole.
3. The hoist must be positioned so that the lifting wire
rope with load does not rub against the side of the
hole, and in such a way that the fixed limit stops on
the wire rope are able to come into contact with the
limit levers on the hoist.
4. The hoist must be wedged so that it does not move
on its bearing face.
5. The platform on which the hoist is placed must have
the required stability and strength to ensure safe
operation.

6. The load must be freely suspended (Fig. 5) or
connected to the unit by means of an idler pulley
mandatorily and strictly located directly below the
unit (Fig. 6).
IMPORTANT
With this installation, never lift a load until it has
been placed directly beneath the hoist, except
when an idler pulley is used.
4.3. Securing the load
The load must be secured using the hook on the lifting
wire rope and never the hook on the hoist.
The load must be secured using a sling with a capacity,
size and type appropriate to the object to be handled.
The hoist wire rope must never be used as a sling,
running it around an object and fastened with its hook
(Fig. 7: correct slinging, Fig. 8: prohibited slinging).
4.4. Installation diagrams
4.4.1. Hoist suspended, load suspended directly
This is the most simple configuration (Fig. 7). The main
precaution to be taken is to avoid any obstacle against
which the load or lifting wire rope could bear laterally
or butt against.
4.4.2. Hoist suspended, direct slanted lifting
This configuration requires a stable slanted plane on
which the load is pulled and maintained (Fig. 9).
4.4.3. Hoist suspended, indirect pulling or lifting
This configuration requires an idler pulley secured to a
fixed point (Fig. 11). Also see section 5.5.
4.4.4. Hoist secured horizontally for direct pulling
To ensure safe use of the unit, neither the hoist or
wire rope should touch any object when tensioned (Fig.
10) at any time.
Check that you have perfectly aligned the unit on the
wire rope by anchoring the hoist so that it can swivel
freely, for example using a sling.
Never secure the hoist rigidly on a structure. Ensure
that the wire rope strands move freely and do not rub
against anything.
Note: If an idler pulley is interposed to hoist the load on
a slanted plane, due to the driving action of the load,
apply the lifting configuration described in section 4.4.3.
