TESTS
(in conformity with machinery EC directive 98/37/EC)
Before setting the machine to work it must be tested in overload under the following condition:
DYNAMIC
TEST
The dynamic test is carried out with an overload coefficient of 1.1 (110% of the nominal load) all movements must
then be carefully carried out without checking the speeds or heating of the motors.
STATIC
TEST
The static test is carried out with an overload coefficient of 1.25 (125% of the nominal load).
This test must be carried out in the absence of wind.
It consists of lifting the nominal load a minimum distance from the ground and then adding the extra weight
without jerks.
Remarks
Loads used in functional tests must be checked with precision dynamometers complete with a certificate to
attest its efficiency and an adequate metrological sensitivity. Certified loads may be used as an alternative.
At the same time as the static test, a measurement of the main girder's deformation is usually taken.
Unless otherwise indicated in the contract there are no compulsory limits to the elastic sags.
The old rule of judging the strength of a machine on the basis of the lowest sag has fallen into disuse.
In practice the value of the sag should be considered exclusively on the basis of the use of the machine.
DOCUMENTATION
Unless otherwise requested in the contract, the following certificates guaranteeing the quality and strength of the components are
supplied with the machine.
• Certificate for the wire rope installed on the machine with all the construction features and the manufacturer’s name.
• Certificate for the hook giving the quality of the material, size and the manufacturer‘s name.
• Declaration of conformity according to European Community Directive 90/37/EC (and amendments thereof).

WARNINGS
UORI ESERCIZIO
lf the machine is to work in hazardous areas we guarantee that all components are made in conformity with European regulations and
all electric parts are legally certified in compliance with EN 60079. All of the electric components enclosed in explosion-proof cases
are supplied with certificates issued by authorized European Institutes.
