INSTRUCTIONS FOR MAINTAINING MACHINES IN GOOD RUNNING ORDER WHEN INOPERATIVE
When, due to particular applications, service is irregular or perhaps the machine remain inoperative and stationary in an especially aggressive area the
follow measures should be taken:
• Put the machine through all its movements every day, completing at least 3 working cycles, even with no load.
• Check the condition of the limit switches every 15 days. For limit switches made up of micro-switches arranged along the drum
and for the travelling, pins, saddles and moving joints must be lubricated using water-repellent silicone-based Vaseline. Also
check that the mechanical parts are moving easily. After this carry out a practice no-load test with the proper care.
• The push-button control panel should be kept covered, protected from humidity and dust in a vertical upside - down position.
(Otherwise, not with standing the cable glands, water will get in through the hanging cable).
EVERY MONTH
• Check the condition of the disk or shoe brakes; clean and lubricate the moving joints of the latter.
• Check and lubricate any monorail trolley unprotected gears.
• Clean all mono rail lower flanges and gantry rails.
• Remove all dirt, grease, oil sand or oxidation dust, from all rotating parts with particular regard to auxiliary units (levers, small
pistons, pin axles).
• After having opened the containers spray all electric component with appropriate specific lubricants and water-repellents.
• Check that anti-condensation heaters are working properly and the relative thermostat is not worn or inefficient. For this
purpose it is essential that the main isolating switch, placed at the beginning of the feeding point, always stays "on".
ANTI-OXIDIZING PREVENTION PROCEDURE
All unvarnished machined surfaces, both internal and external, must be cleaned, dried and coated with rust preventer, which will
guarantee a protective coat for at least 12 months, on condition that it is not burned, dissolved or mechanically removed
• For external surfaces, the anti-rust treatment is made with a compact coating of high-quality anti-corrosive agent
• For machined surfaces inside an assembled unit, the anti-rust treatment will be of a type which does not require to be
removed before using the machine
• Admissible methods for applying anti-rust treatment are: spray, brush, by filling, etc., through all available openings or
disassembling, if necessary, the parts to coat completely and protect all internal machined surfaces. Particular care must be
used with all the open surfaces of rolling and sliding bearings, so that they are completely coated
Paints and Protective Substances
Finished surfaces subject to oxidizing or corrosion must be coated, by spraying, brushing or dipping, with an easily removable
protective substance against water and hydrocarbons, which is fully compatible with materials and surfaces to be protected.
No anti-rust protective substance can be used on electric parts such as switches, rotors, distributors, brushes, terminals, connectors
or other non-metal parts such as friction disks, brakes, rubber, plastic, fabric or leather. When the anti-rust substance precludes the
use of such components, make sure it is completely dry before assembling the latter.
All protected surfaces must be isolated from touching wood or other hygroscopic materials by means of wax or polyethylene sheets or
other similar products. In special cases, impregnating paper may also be used for coating surfaces and materials subject to corrosion.
Such products have the advantage of being easily and quickly removed.
If the protective coat breaks it must be restored to allow storage of goods to continue. Rust preventer must be of a type which can be
removed using mineral turpentine.
• Machined surfaces must be cleaned using petroleum based solvents and dried before applying the rust preventer.
Usually, the rust preventer is not applied on metals which are intrinsically resistant to corrosion, such as:
• Copper, nickel, brass, or other corrosion-resistant metals or alloys
• Surface-treated metals or zinc, nickel or tin coated metals.
• If there is the possibility that the anti-rust products gets in contact with non-steel materials, it is necessary to accurately
select the most suitable rust preventer based on the effects it may have on those same materials.
However, the direct contact between a steaming rust preventer and non-ferrous metals (with the exception of aluminum
and its alloys) must be avoided.
