• Working load limit: the weight of the load suspended from
the shackle must not exceed the recommended working load
capacity of the shackle in ques on, as indicated clearly on the
product.
• Working cycles: the shackles will con nue to operate
correctly as long as they retain their geometric and mechanical
characteris cs. Thus, depending on what they are to be used
for, check the shackles for signs of wear and tear, and that they
are coupled correctly with the cables, chains and/or
accessories. Do not use any shackles that display signs of
reduced cross sec on, deforma on, squashing, bending,
corrosion or instability with the coupling elements. Check the
brackets for cuts, scoring, scratches, cracking, corrosion, sharp
edges, and wear and tear resul ng from improper use. Make
sure that the pins do not display signs of bending, wear and
tear, cuts or scoring, and that the thread is not damaged in any
way; in the case of shackles with threaded pins, it must be
possible to screw the pins in completely, without any
irregulari es; in the case of shackles with nuts and split pins, it
must be possible to screw the nut all the way onto the pin
without any irregulari es, and the split pin must be present at
all mes. Do not use shackles with nuts and split pins where the
nut and/or split pin is not present.
-The safety factor defines the degree of safety with respect to a
product. While this value may be very high in certain cases, the
maximum working load should not be exceeded under any
circumstance, since this could result is serious damage and
even breakages in extreme cases. The material from which a
product is manufactured is also taken into account when
calcula ng the safety factor. This means that the safety factor
also indicates a certain degree of protec on against
phenomena such as wear and tear that may result from heavy-
duty and con nual usage.
ATTENTION: improper or incorrect usage of li ing accessories
may generate a series of hazards, placing the operator, the
personnel assigned to carry out the handling and li ing
opera ons, the li ing equipment, personnel present in the
vicinity, surrounding structures and objects and anything else
that may be present with the radius of ac on of opera ons to
be executed at the risk of serious injury and/or damage. Before
carrying out any manoeuvres it is necessary to evaluate all the
poten al risks in order to avoid causing irreparable damage.
-The following factors should be taken into account when
selec ng the shackles:
• Coupling element: the shackle must be selected on the basis
of the maximum force that may be exerted by the li ing cables,
chains and/or accessories coupled to it.
The load must be applied to the shackle so that it is stable and
the various components are perfectly aligned. The resul ng
force must always lie parallel to the main axis ɸ of the shackle
body, perpendicular to the shackle pin. Avoid applying lateral
loads as this reduces the efficiency of the significantly with
respect to the working load.
