6.3.4 Cleaning and lubricating the jib crane
•
Cleaning can be performed by personnel who is not highly specialised.
•
It is periodically necessary to keep the following parts clean:
o
jib crane structure
(column, arm, etc.)
o
jib crane mechanisms
(thrust bearing, pins, etc.)
o
jib crane electrical parts
(festoon cable, etc.)
o
components of the lifting and traverse unit
(wheels, chain, hook, block,
pushbutton panel, etc.).
•
Overhead cleaning above ground must be performed by qualified
personnel equipped with suitable means and personal protection
equipment.
•
These operations are necessary on a quarterly basis to permit activation
of periodic tests.
•
Cleaning can be implemented simply with the use of means, equipment and cleansers or solvents
normally used in general cleaning operations for industrial equipment since no particular
contraindications exist in relation to the use of products or materials.
•
Clean by removing any foreign and dirty substances with vacuums, absorbent cloths, etc.
•
Dry any excess grease and/or oil on the parts.
Accurate management of the jib crane mechanism lubrication is a necessary
condition for guaranteeing the effective compliance to its intended service as
well as its duration.
•
The lubricating power decreases over time due to stress, so it is necessary to restore or renew the
lubricants.
•
Lubrication of the jib crane is simple and limited to application of a thin layer of oil or grease, between
the bearings and pins, in the arm rotation points.
•
Instead, the lubrication of the lifting and traverse mechanisms is very important, their lubrication cycles
are contained in the relative technical publications attached hereto.
•
Lubricants, solvents and detergents are toxic/harmful products for health:
o
they can cause irritation if they come into direct contact with the skin
o
they can cause serious intoxications if inhaled
o
they may be fatal if ingested
•
Handle with care using adequate personal protection equipment (PPE). Dispose of
correctly in compliance with current laws on toxic/harmful waste.
