This equipment has been designed to be tested:

- in a dynamic situation, with coefficient 1.1 For the dynamic tests will be added an overload of 10% at rated load, whether electric or manual lifting. The tests are therefore performed on all movements (lifting, travelling, translation, rotation etc...) It will not be necessary to lift the load to its maximum height but it is possible to do it and no time is imposed. One move of each movement is necessary and sufficient.

Interpretation of dynamic tests: During these tests the hoist trolley + trolley must remain stable. Ensure no visible distortion too important. Measure the height under beam or over beam empty before applying the load ( Load at the end of the arm if it is a jib crane or at the center if it is a gantry crane ) and remeasure under dynamic load. Do the ratio to recalculate the measured defl ection under dynamic load by dividing by 1.1 in order to interpret Deflection under nominal load, this defl ection is directly proportional to the load. Only the defl ection under nominal load is interpretable to the exclusion of any other! Defl ection observed (interpreted under nominal load) must not exceed 1/100th of the span of the jib cranes and 1/200th of the sum Height + Span. For wall jib cranes deflection should not exceed 1/200e of the span (it will not take into account the possible deformation of the post which is supposedly of sufficient size and have been calculated by the user ) If the dynamic tests give satisfaction, there will be static tests.

In a static situation: - at a coefficient of 1.5 for machines using human power - at a coefficient of 1.25 for other machines

Static testing has for single purpose to ensure the strength of the assembly and verify the absence of permanent deformation or residual. No deflection measurement shall be interpreted during these tests if it is only to verify the absence of permanent deformation



Requirements during the static tests: For static tests, it will be an overload applied in more than 25% of the rated load, whether it be a manual or electric lifting. These tests will be performed only on the lifting arms of the bracket in the center position (end of the load arm in the case of jib crane and to the center of a gantry). It is forbidden to lift the load increased by 25% with the device but additional weights are added to the dynamic load. In the case of a wall jib, the static test will be done in the sense that less strains the the building structure. The duration of this test shall not exceed 30 min.

Interpretation of static tests: If after static tests, no permanent or residual deformation is found, the device can be operated. As defined in the European Machinery Directive, any calculation notes will not be issued unless requested to ordering and duly accepted by Comege, as well as the detailed plans, schedules etc. .... which are the subject of the information folder and as such are confidential documents.

Concerning electric chain hoists: It is reminded that these devices are equipped with torque limiters and not load limiters. Also for security reasons, their setting far exceeds the trigger threshold 110% of the rated load. It is quite acceptable that the torque limiters can be «calibrated» to 125 or even 130% of rated load. This measure aimed to anticipate wear slip friction system providing torque limit and prevent and to the risk of «slippage» of the load.

A periodic maintenance check is required at least once a year:

In accordance with regulations, the user must keep an inspection booklet recording all the inspections and operations carried out on the machine (Rule FEM 9755).

In France, since 1 April 2005, the owner of a lifting machine must: 1. Pursuant to the provisions of the order of 2 March 2004, keep a maintenance log in which the

following must be recorded:

Maintenance operations performed in accordance with the recommendations of the manufacturer All other operations (inspection, maintenance, repairs, replacement or changes to the machine)

The following must be recorded for each of these operations: the date of the work, the names of the people and, where appropriate, the companies which carried out the work, the nature of the operation and, if it is a regular operation, the frequency. If the operations involve the replacement of certain machine components, the references of these components must be indicated.

2. By virtue of the order of 1 March 2004, article R 232.12 of the Labour Code:

Checks during set-up (section 3 of the order - articles 12 to 17):

Suitability test (article 5-1): suitable equipment and compliant installation. It must be provided, in writing, by the user (article 3d). Assembly and installation test (article 5-11): equipment installed according to the instruction

manual. Operating test (article 6c or 14-II): loaded with safety tests. Static test (art. 10) Dynamic test (art. 11)



Regular general checks (section 5 of the order - articles 22 to 24):

Inspection of the state of preservation (art. 9): equipment kept in good condition, with nothing missing or added, compliant. Operating test (art. 6b and c): loaded with safety tests. Checks when resuming service (section 4 of the order - articles 18 to 21): Suitability test (art. 5-I): suitable equipment and compliant installation. It must be provided, in

writing, by the user (art. 3d). Assembly and installation test (art. 5-II): equipment installed according to the instruction manual. Inspection of the state of preservation (art. 9): equipment kept in good condition, with nothing

missing or added, compliant. Operating test (art. 19-II): loaded with safety tests. Static test (art. 10) Dynamic test (art. 11)

8 – Taking out of use

If the equipment is in a state of disrepair likely to give rise to risks, the user is obliged to ensure that this equipment is eliminated, i.e.: prevented from operating and possibly disassembled.
