Check the efficiency of the sliding limit strokes every three months:
•
Check their conservation status and operation (allow the limit switches to intervene several times) and
specifically, check their operation during a normal manoeuvre with a full load, testing at low speed first (where
this speed option is available);
•
Control to make certain all cable runs, covers and seals are properly fitted;
•
Check all moving mechanical elements (levers/springs) and tighten all screws.
•
The limit switches are safety devices – as such their malfunctioning can compromise
the safety of persons exposed!
•
Do not hesitate to replace limit strokes being tested if they do not appear to
sufficiently satisfy operating reliability.
•
Never carry out hasty repairs on the limit strokes!
•
Use original spare parts.
Check the efficiency of all cables and electric conductors every three months:
•
Check all flexible cables for cuts, abrasion, peeling and uncovered conductors;
•
Check the efficiency of all conductors and ground connections on the electric motors, controlling and tightening
all screws and terminals.
•
Check all seals on the covers and cable runs.
•
Check to make certain the identification nameplates are present on the motors, and in good condition.
•
Replace any cables and/or conductors that appear broken, cut, peeled or eroded.
•
Never carry out hasty repairs.
6.3.4 Cleaning and lubrication
•
“DGT” drive units or endcarriages must be thoroughly cleaned every three months,
in order to allow for periodic control checks;
•
Cleaning operations above ground level must be carried out by qualified personnel
making use of suitable equipped with individual safety and protection devices.
•
Cleaning operations can be performed simply using tools, detergents or solvents commonly employed in general
cleaning operations on industrial equipment.
•
Remove smudges, stains and other foreign substances with an aspirator, absorbent cloths, etc.
•
Sliding reducers on the “DGT” drive units and endcarriages are lubricated for life
and do not require lubricant replacement.
•
However, since the proper lubrication of mechanisms on the reducers is an
essential condition in guaranteeing their effective operating response and duration,
on a monthly basis visually control that there are no lubricant leaks on the reducers.
•
If significant leaks are detected, immediately contact the servicing department at
DONATI SOLLEVAMENTI S.r.l.
•
Lubricants, solvents and detergents are toxic/harmful products for our health which can:
•
produce irritations in direct contact with skin;
•
provoke serious intoxication if inhaled;
•
cause death if swallowed.
•
Handle with care using suitable individual protection and safety equipment;
•
Do not disperse in the environment, dispose of in conformity with current legislative
ordinances in force regarding toxic/harmful substances.
