5 MAINTENANCE, CONTROL AND REPAIR
5.1

MAINTENANCE AND CONTROL

Generally, the overspeed governor and respective tension weight with counterweight do not need any mainte-
nance.
The whole plant has been conceived in such a way that, with proper use without damages, there is no need for
important maintenance interventions.
According to the frequency of use, controls of the plant should be carried out periodically.
After substantial changes or after an accident, it is necessary to carry out a control of the plant (see
EN 81-2, annex E2).
This is necessary especially when safety devices are changed.
Changes, damages or other irregularities must be notified and, if necessary, repaired within the limits of the al-
lowed feasibility.
Periodical controls increase, not only the safety, but also the trouble-free and long-life operation of
the plant!
Particularly recommended are controls and maintenance operations before the operating tests foreseen by the
law take place.
Please contact your supplier if there are any doubts regarding the operation efficiency of the components of
the plant.
MAINTENANCE AND CONTROL SCHEDULE
• Check every 6 (six) months the operation efficiency of the overspeed governor.
• Check the damage or the distortions of the overspeed governor and respective structural elements.
• Check the wear of the undercut grooves of the overspeed governor and the grooves of the tension pulley.
Danger of tear to the rope! When the governor rope runs in an irregular way, that is to say when the
outline of the rope remains stamped in the groove of the overspeed governor.
• Control that the rocker lever is easily movable. If necessary, replace it.
• Control the safety switch by hand (manual release).
• Keep the plant clean from dirt and particularly the signs and the type-plates must always be kept legible.
5.2

EXECUTION OF REPAIRS

Generally, also in case of repairs, the overspeed governor cannot be disassembled or modified in any other
way (sealing, sealing-wax).
It is not allowed the spontaneous replacement of parts or element groups due to defects or severe
wear.
The reasons are the following:
• rules and regulations concerning guarantee and safety technical dispositions;
• only original spare-parts must be mounted.
It si no allowed to operate the elevator plant, even if temporarily, without the overspeed governor.
