$YNAMICTESTRUNS
฀ •฀ prepare฀ adequate฀ weights฀ for฀ the฀ test฀ runs฀ with฀ load฀ equal฀ to฀
nominal lifting capacity x 1,1 and suitable
equipment for the harnessing and lifting of the load.
฀ •฀harness฀the฀load,฀taking฀care฀to฀position฀the฀hook฀vertically฀to฀avoid฀skew฀rope฀falls.
฀ •฀
slowly tension the sling so as not to cause tearing, if available do the test runs with load using the “slow” speed.
฀ •฀slowly฀lift฀the฀load฀and฀check฀that฀this฀happens฀with฀no฀difficulty฀and฀that฀there฀are฀no฀anomalous฀noises,฀clear฀
deformations or sagging in the structure of the crane, in the support structures and/or the anchorings.
฀ •฀repeat฀the฀test฀run฀at฀maximum฀speed,฀if฀available,฀doing฀the฀preceding฀checks.
฀ •฀
check the functionality of the “ascent and descent” limit switches, when installed, and/or any clutch device fitted.
฀ •฀check฀the฀functionality฀of฀the฀lifting฀brake,฀checking฀that฀the฀weight฀is฀braked฀in฀adequate฀time฀and฀that฀there฀is฀
no skidding of the load, after releasing the button.
฀ •฀ carry฀ out฀ the฀ same฀ checks฀ also฀ for฀ the฀ trolley฀ travelling฀ movements฀ and฀ rotation฀ of฀ the฀ arm,฀ checking฀ the฀
functionality of the limit switches, without bringing the load to the maximum height (lift it to a height of one metre
from the ground).
฀ •฀operate฀first฀at฀slow฀speed,฀if฀available,฀and฀then฀at฀maximum฀speed.
฀ •฀check฀the฀correct฀sliding฀of฀the฀trolley฀on฀the฀girder,฀and฀ascertain฀that฀there฀are฀no฀no฀anomalous฀noises,฀evident฀
permanent deformations or anomalous sagging of the structure of the crane, of the support structure and/or the
anchorings.
฀ •฀check฀the฀functioning฀of฀the฀“emergency฀stop”฀button฀which฀must฀stop฀and฀inhibit฀all฀the฀movements.฀Any฀
function of the hoist and/or trolley must stop, in the shortest possible time and space, without showing anomalies,
side skids, dangerous oscillations, etc. which threaten the stability.
฀ •฀check฀the฀braking฀spaces฀and฀stopping฀spaces฀during฀lifting฀travelling฀and฀rotation,฀checking฀the฀stability฀of฀the฀
mass manoeuvred.
3TATICTESTRUNS
฀ •฀use฀suitable฀masses฀for฀the฀test฀runs฀equal฀to:฀
nominal lifting capacity x 1,25 and suitable equipment for slinging
and lifting the load.
฀ •฀put฀in฀the฀sling฀the฀load฀
used for the dynamic test runs (nominal capacity x 1,1) taking care to position the
hook on the vertical to avoid skew runs.
฀ •฀tension฀the฀sling฀slowly฀to฀avoid฀tearing,฀if฀available฀carry฀out฀the฀test฀runs฀using฀the฀“slow”฀speed.
฀ •฀lift฀the฀load฀and฀stop฀it฀in฀a฀suspended฀position฀at฀a฀height฀of฀10cm.
฀ •฀gradually฀apply฀weight฀on฀it฀until฀reaching฀an฀overload฀value฀equal฀to฀25%฀of฀the฀nominal฀lifting฀capacity
฀ •฀leave฀the฀weight฀suspended฀for฀no฀less฀than฀10฀minutes.
฀ •฀check฀that฀the฀weight฀suspended฀(load฀+฀overload)฀does฀not฀yield฀(the฀lifting฀brake฀and฀the฀clutch฀device/load฀
limiting switch, if installed, must not skid).
฀ •฀release฀the฀load฀and฀check฀that฀there฀are฀no฀evident฀deformations฀and/or฀sagging฀of฀the฀structures฀of฀the฀crane,฀
the support structures and/or the anchorings.
The฀dynamic฀test฀run฀must฀be฀carried฀out฀in฀the฀most฀unfavourable฀load฀conditions,฀that฀is฀combining฀
lifting, travelling and rotation.
•฀During฀the฀static฀test฀run฀NO฀movement฀of฀the฀crane฀must฀be฀activated.฀
•฀The฀testing฀of฀the฀jib฀crane฀must฀be฀repeated฀at฀the฀annual฀checks฀
(see paragraph 6.3.2).
