Operational Safety
• Check the grapple for damages at the beginning
of each shift. Tighten all fasteners regularly.
• Make sure that the hydraulic pressure in the
grapple cylinder is adjusted according to the
specifications. If the pressure is too low the
grapple will not be able to carry its load. If the
pressure is too high, the grapple will be
overloaded, which could cause a structural
failure, resulting in injury and/or property
damage.
• The grapple must not be used for lifting
personnel.
• The grapple is not designed for handling rocks,
heavy spare parts, etc.
• The grapple arms on the SuperGrip II-A must
NOT be used to dig up stumps and rocks.
If used as described above the grapple arms or other
parts of the grapple could fail, resulting in injury and/
or property damage.
• The load of the grapple must not exceed the
recommended maximum rating as structural
failure could occur, resulting in injury and/or
property damage.
• When operating this equipment ensure all
unauthorized persons remain at least 15 meters
clear of the machine.
• The operator must immediately evict
unauthorized persons who are in the danger zone
or are heading towards the danger zone
• Personnel inside the danger zone must be well
protected against falling load.
• Personnel inside the danger zone must keep clear
of hanging load.
• The operator should be aware that the load, or
parts of the load, could fall from the grapple at
any time.
