OVERLOAD TESTS
The European Machinery Directive requires that all lifts are tested under dynamic (+10%) and static (+25%)
overload conditions prior to their commissioning. These tests must be carried out only an authorised
competent person. The result and date of these tests as well as the name, occupation and address of the
person who has carried them out, must be recorded in a log or notebook that includes the identification
details of the lift.
CAUTION: DURING THESE TESTS, THE SETTING OF THE PRESSURE RELIEF
VALVE SHOULD BE ALTERED FOR THE DYNAMIC TEST AND THEN RE-SET.
THE LIFT MUST NOT BE OPERATED DURING THE STATIC TEST.
