Maintenance registry
In order to cope with problems like the wear of the mechanic and electronic components, and
the grip load devices, it is necessary that one carries out a regular and systematic
maintenance.
The maintenance and respective time intervals must take place according to the indications of
the manufacturer shown in the instructions manual of the instrument.
The maintenance interventions must be made only by specialised and qualified personnel.
The maintenance person must have attended training courses and must know the safety
norms in the use of crane scales and concretely apply them.
In this booklet the user must document in chronological order all the maintenance interventions
carried out on the crane scale (inspection/control, revision, repair), as well as any fact or
particular event which might have influenced safety matters.
Upon receipt of the crane scale, or at least before the commissioning of the instrument, record
all dimensions of the hooks and shackles in the service manual. All subsequent dimensional
checks specified in the plan check and maintenance, will be compared with the first
measurements and the tolerance limits given in the above table, refer to the actual size
detected in the first inspection.
In the following pages of this booklet there is a “maintenance registry” in which all ordinary and
extraordinary maintenance interventions on your instrument, should be reported.
All information is very important and can invalidate the validity of the warranty in the case that
it’s not reported in detail and accurately. It is also advisable to make sure that:
- the internal responsible person carries out the quarterly verification and regularly records it on
this booklet;
- the authorised personnel stamps the appropriate box at the end of each annual maintenance
intervention.
