The personnel assigned to jib crane maintenance must:
o
be well trained
o
have read this publication
o
have an in-depth knowledge of accident prevention laws
o
Unauthorised personnel must remain outside of the work area during
operations
These measures are cited and further described in this chapter, each time a procedure is required that may
entail a risk of injury, damage or accident, using the
WARNING
and
HAZARD
notes:
The WARNING notes precede an operation that, if not correctly performed, may cause
damage to the crane or its components.
The HAZARD notes precede any operation that, if not correctly performed, may cause
an operator accident.
Pay attention to the following WARNING NOTES during the maintenance phases:
Before restarting the jib crane, after a fault, it must be carefully inspected and
controlled to discover any damage and the procedure described in paragraph
5.3 must be repeated
Never intervene on the setting and positioning of safety devices unless
expressly required to eliminate a fault. Tampering with them may cause
serious damage to the crane or its components.
Pay attention to the following HAZARD NOTES during the maintenance phases:
Disable the power to the crane electrical components before performing
maintenance operations unless the power is necessary. Affix a sign stating:
MACHINE MAINTENANCE - DO NOT TURN ON THE POWER
Never disable the safety and protection devices installed on the jib crane. Use
specific warning signs if it becomes necessary and work with utmost caution
Always make sure of the presence and suitability of the earth connections
and their compliance with the law. Lack of an earth connection for the
electrical equipment may cause serious injury to people.
