General warnings

The electronic crane scale is to be considered a scale, and therefore use must be limited only to weighing needs. The

crane scale is not designed for cargo handling and transportation. Once the load harnessing operation is done,

move away, and make sure that the load is well balanced lifting it up only a few centimetres from the ground and then lift the load down to the ground again. Remove the crane scale at the end of the weighing operations.

Do not stand or pass under a suspended load

DO NOT exceed the nominal capacity of the crane scale. (The illustration refers to the model 6t. Refer to the maximum capacity of the purchased instrument).

The nominal capacity of the electronic crane scale must not be lower than the maximum capacity of the lifting device.

DO NOT exceed the nominal capacity of any support element of the load if lower than the capacity of the crane scale.

Use the scale EXCLUSIVELY for the lifting and the weighing of suspended loads and for TENSION measurements. Suspended loads which may cause applied torsion stresses MUST be hung with flexible or swivelling bindings.

Carefully respect all the safety measurements established by the manufacturer of the electronic crane scale, which are shown in the instruction manual.

Entrust the installation, set-up, maintenance, operations only to trained personnel. Entrust the execution of maintenance operations only to trained personnel in security controls for lifting devices.

DO NOT spill liquid on the instrument. Respect the IP degree protection of the instrument. DO NOT use solvents or industrial chemicals for cleaning the instrument.

The crane scale is to be considered like a scale, and therefore it must be used only for weighing needs. The crane scale is not designed for cargo handling and transportation. Once the load harnessing operation is done, move away and make sure that the load is well balanced lifting it up only a few centimetres from the ground and then lift the load down to the ground again. Remove the crane scale at the end of the weighing operation. An improper or different use than what is foreseen in this manual, will release the Manufacturer from all responsibilities in case of damages caused to people or things.

Organisational measures of the user company

- Respect the safety measures established by the manufacturer of the electronic crane scale,

the manufacturer of the lifting device, and eventually of the safety board of the product to be weighed.

- The electronic crane scale must be used only for the foreseen purposes.

MAINTENANCE AND CHECKS

The electronic crane scale and all lifting accessories must be regularly subjected to inspection and maintenance. For the prevention of accidents or damages, it is necessary that the maintenance is done according to the manufacturer's instructions. Maintenance must be performed only by persons who have acquired the necessary technical expertise. To ensure a safe operation, follow these instructions:

- carry out a continuous regular maintenance and cleaning.

- entrust the maintenance and repair operations only to trained and authorized personnel

- use only original spare parts.

- do not use the electronic crane scale where there is non-compliance with the safety

checklist.

- any maintenance, repair or cleaning should be done away from danger areas and with the

electronic crane scale turned off.

Daily monitoring

Each time the operator starts a new work cycle with the electronic crane scale, one must:

- check all instrument parts;

- carry out a general visual inspection of the whole system;

- Check the integrity and efficiency of all parts of the weighing system like the safety lever of

the hooks, the locking nuts screwed well with the pin, the shackles, etc..

Regular Maintenance

Maintenance should be carried out only by persons who have acquired the necessary technical expertise and are specialized and trained for this purpose.

Every 3 months

- Check all dimensions of the parts which make up the

instrument;

- Check the wear on the handle or the eyelet, by

checking if there are any plastic deformations, mechanical damages(irregular), cracks, corrosion, damage to threaded portions and the twists;

- Check the tightness of the splice plate on the hook,

and the presence of defects, and ensure its proper functioning;

- Make sure that the split pin and the shackle nuts are

firm;

- If other metrological and mechanical irregularities

are detected, have the electronic crane scale repaired by qualified personnel (authorized assistance service).

An incorrect measurement of weight may be a sign of a mechanical problem with the crane scale. If the crane scale weighs incorrectly, the crane scale must be repaired by skilled personnel (Authorized Service Center). Do not for any reason carry out the repair by yourself. In case of non-compliance turn immediately off the electronic crane scale. All repair operations and the parts used are classified and stored in the maintenance register.

Every 12 months

All of the elements that transmit the load, including the load cell, should be checked by specialised personnel qualified in inspection and maintenance of cranes and bridge cranes.

It is of utmost importance that all the maintenance and repair operations, and the used components are recorded and filed in the appropriate product maintenance registry.

For further information on regular checks, see the following table which refers to the standard UNI EN 13889:

Form and structure of the shackle:

The shackles should be examined regularly by a qualified person. The time interval from one check to another depends on how much the instrument is used, but it is recommended to not exceed six months. Therefore, one must:

- always inspect the shackle before use;

- carry out regular visual inspections to look for nicks, cracks, wear or damaged areas,

damaged threads on the pivot and body; if it is necessary, carry out a magnetic test or nondestructive testing;

- keep a file in regards to the accessory sheet and keep track of the checks;

- the shackles which do not fully or partially satisfy the requirements, must be discarded.

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.
