•Checkthatthevoltagevaluetothemotorsiswithinthelimitsof+/-10%ofthenominalvalue.
•Checktherearegroundclampsandthattheyareconnectedcorrectly.
s#HECKTHECORRECTINSTALLATIONOFTHECRANE
•Checktherearenoobviousfaultsfollowingtheinstallationofthecrane.
•Checkthatalltheboltedjointsarecorrectlytightened.
•Checkthattheslidingtrackofthetrolleywheelsisintact,whichmustbefreefromobstacles,upwardprojecting
bumps, depressions, and foreign bodies.
•Checktheuniformsensitivityoftheflexingofthearm,inallitsamplitude.
•Checkthatthearmcanfreelyrotate,relatedtotheabsenceofobstaclesinthewholeareaofoperationofthe
crane and any interference.
•Adjusttheascentlimitswitchesoftheelectrichoist(seeinformationintherelated“Instructionsforuse”),toallow
the maximum possible run. The ascent limit switch must be adjusted so that the hook at its lowest point is about
10 cm from the ground.
•Checkthatthereareendcatchesand/orstrikerplatesofthearmandtrolley.
•Checktherearestrikerplateswhichfunctionfortheinterventionofthetravellimitswitches,wheninstalledwith

•Checktherearenoleaksoflubricant.
• Check during the trial runs that there are no strange noises and/or vibrations and/or incorrect movements
(skidding of the wheels or, spontaneous movements of the trolley and/or the arm, etc).

case, avoid intervening using the lifting limit switch.
•Iftherotationdirectionofthemotorsdoesnotcorrespondtothecontrolsofthepush-buttoncontrol
panel the limit switches do not halt the movement, and malfunctioning can occur.
•Ifthedirectionofthemovementdoesnotcorrespondtothefunctionshownonthepushbutton
