•฀Check฀the฀stability฀of฀the฀arm฀when฀empty฀and฀when฀fully฀loaded,฀at฀the฀end฀points฀and฀intermediate฀points฀of฀
rotation; then checking that the arm, in any point of the rotation, keeps its position with moving
spontaneously.
•฀ When฀ necessary฀ have฀ the฀ brake฀ of฀ the฀ crane฀ adjusted,฀ as฀ described฀ in฀ paragraph฀ 6.4.1฀ “Adjustment฀ of฀ the฀
rotation brake of the crane arm”, on page 56.
•฀Check฀the฀efficiency฀of฀the฀festooned฀power฀cable,฀check฀there฀is฀no฀peeling,฀cuts,฀lacerations฀or฀other฀changes฀
in the protection sheath.
•฀Check฀the฀seal฀of฀the฀protectors,฀the฀power฀cable,฀their฀clamps฀(in฀the฀connector฀block)฀and,฀if฀necessary,฀tighten฀
them correctly.
•฀Check฀the฀efficiency฀of฀the฀conductors฀and฀the฀grounding฀connections,฀carrying฀out฀a฀check,฀and,฀if฀necessary,฀
fixing all the grounding screws.
•฀Carry฀out฀a฀check฀of฀all฀the฀weather฀strips฀of฀the฀covers฀and฀the฀cable฀clamps.
•฀Check฀there฀are฀warning฀plates฀and฀that฀they฀are฀visible.
Quarterly฀check฀of฀the฀efficiency฀of฀the฀brake฀of฀the฀rotation฀arm฀of฀the฀crane:
Quarterly฀check฀of฀the฀efficiency฀of฀the฀electric฀power฀supply:
•฀ Replace฀ the฀ clutch฀ plates฀ of฀ the฀ brake฀ when฀ there฀ is฀ instability฀ of฀ the฀ arm฀ after฀
adjusting฀the฀brake.
IN฀CASE฀OF฀ANOMALIES:
•฀It฀is฀forbidden฀to฀carry฀out฀corrective฀maintenance฀work฀on฀the฀brake฀of฀the฀rotation฀
arm฀of฀the฀jib฀crane.
•฀Any฀operation,฀outside฀normal฀maintenance,฀on฀the฀brake฀of฀the฀rotation฀arm฀of฀the฀
crane฀can฀be฀done฀by฀the฀assistance฀service฀of฀DONATI฀SOLLEVAMENTI฀S.r.l.฀or฀by฀
staff฀authorized฀by฀them.
•฀Do฀not฀hesitate฀to฀replace฀the฀electrical฀component,฀if฀it฀is฀no฀longer฀giving฀sufficient฀฀
guarantee฀of฀functional฀reliability
•฀Never฀carry฀out฀improvised฀repairs
•฀Use฀original฀spare฀parts
For information about checks of all the structural, mechanical and electromechanical components of
teh฀lifting฀and฀translation฀units฀of฀the฀jib฀crane,฀see฀the฀relevant฀documentation฀included฀in฀this฀
technical publication
•฀Don’t฀hesitate฀to฀replace฀the฀part฀and฀/or฀the฀component฀in฀question,฀when฀it฀no฀longer฀gives฀
sufficient฀guarantee฀of฀safety฀and/or฀functional฀reliability.
•฀Never฀carry฀out฀improvised฀repairs!
