When installing BLOCK onto a machine and before putting it into operation a specialist
must verify that it is in working order. They will check:
• That the stipulated distance is being covered.
• That there is no loss of fluid from the supply.
• That the pressure of the feeding fluid is correct.
• That the mechanised jaws that hold the workpiece don’t have sharp edges, or burrs
that may result in injury or scratches obtained by the operator.
It must also take into consideration that the block’s jaws are mobile and have an
automatic stroke per jaw, which may produce an entrapment hazard. Entrapment may
lead to serious injury.
The operation of the machine where the Block is installed must impede the operator
from being able to place their hands in the work area while there is the possibility that
the pieces are moving. To this end, physical barriers such as doors or inaccessible areas
are to be enforced.
During the opening and closing of the Block, the operator will not be able to access the
area where it is installed. The jaws should be designed in such a way to allow the work
piece to remain situated on the Block so that when it is activated, the operator never has
to hold the part with his hands.
Before opening the doors, ensure that all mobile parts have reached their final destination.
Risk of injury due to incorrect clamping of the piece
A pressure of the feeding fluid that is too low may result in the work piece being ejected
outside of the Block and therefore result in serious injury.
A pressure of the feeding fluid that is too high may result in damage to the supply hose
of the Block as well as the work piece being ejected and therefore result in serious injury.
The pressure of the supply (air, oil) must be checked periodically as well as the condition
of the supply hose.
2.8 failures
Should a failure in the Block occur that puts safety at risk or it is suspected that the
position of the Block may be problematic due to the production features, the machine
that the Block is attached to must be retained immediately and remain closed until the
failure has been located.
2.9 Fluids used.
It is necessary to check whether users have any allergies provoked by skin contact with
lubrication grease or with the feeding oil that is used in the Block’s routine operation.
To avoid these risks the use of gloves is recommended.
