I would recommend using a wire rope lubricant, liquid type and not a grease. Grease is going to be to thick to penetrate to the core of the rope and will only really lubricate the outside of the rope. A penetrating type wire rope lubricant will penetrate to the core and lubricate the entire bundle of individual wires.

My suggestion would be something like TRC Wire Rope Lubricant or whatever the equivalent would be in your country.

Michael,

Fully agree with you in not applying a grease!
I also looked at your product, for the flash point of 125 F (~52 C) I would guess it has some solvent or diluting agent, is that the case? We stop using products containing solvents with flash point below 104 C (~220 F) many years ago for safety reasons, for environmental pollution and more important for occupational health. To apply lubricants with solvents and have to breath hydrocarbons all over is not a pleasant job.

I would guess there are good penetrating oils for wire rope lubrication that is preventing wear and corrosion and with no solvents. A low viscosity one do you think will be adequate or high viscosity?

I agree that using a solvent as a carrier isn't the ideal situation but it works. The idea is that in it's "out of the can" form it is thin enough to penetrate to the core of the wire rope and as the carrier evaporates leaves a adhesive/cohesive coating to lubricate the bundle.

The problem with starting off with a higher viscosity oil would be its difficulty in penetrating the whole way through the wire rope bundle, especially on 1" or larger wire rope. Basically your left with lubricant on the exterior and not the interior.

I don't have the MSDS with me currently but if I remember correctly the carrier is stoddard solvent. I'll actually be going down to Ft. Worth on Friday for a meeting we are having with Lubrizol. I will have to mention the environmental impact and see if it could possibly be formulated with something like alcohol as the carrier. That would provide the low viscosity and evaporation characteristics.

Mr. Michael,I can not agree with your point. The moment i say grease, it does not refer to only a semi solid type material. Grease with NLGI-00 and NLGI-000 cosistency are being used in many applications where traditionally Lubricating oils were used. The use of softer grease type lubricant has also been increasing in many applications. For one such eg.refer"Grease for gear lubrication" ,J.SOc Trib and Lub engg, Page 557, sept 90.
My point is that softer grease (NLGI-00/000) can able to penetrate to the core of the rope and can lubricate entire bundle of indiviual rope much efficienty. Unlike in oil, it does not require diluent to carry the oil into the core of ropes. SOfter grease fortified with solid lubricant would take care of the rope working under severe conditions.

Cheers...

I just don't see a NGLI# 00 or 000 grease penetrating to the core of a 1 to 2 inch wire rope bundle. It would have to soak through a 1/2 to 1 inch of the bundle to get to the center.

Many steel plants are using NLGI-00/000 grease sucessfully with out any problem for quite long period. Ofcourse application method also important.
So i dont see your problem of softer grease not penetrating thru core. Many suppliers including Shell, Rocol are supplying nlgi-00 grade grease for Wire rope lubrication.

Cheers

Perhaps the concept of 6 month lifetime for wire ropes at steel plants to renew them is considered normal but in fact it is too short.
Can we target 1 year lifetime and see if grease lubricated or oil lubricated wire rope will hold longer?

Anybody has experience in a comparative test like this?

I really dont know much about wire rope lubrication, but I belive this Norwegian supplier has a good solution;:

Perhaps a good penetrating oil can do the job without need of a lubricator.

A good Wire Rope Lubricant should be able to penetrate to the core, hence should be be of low viscosity. It should provide good lubrication hence an additive packaged oil would be a better option, rather than straight mineral oils. It should repel water or moisture and prevent rust.

Most of these applications for wire rope would be over large tracts of land or water, hence the product should also be biodegradable.

Solvent based, Bitumenous based or greases are no longer recommended now.

I have seen that Rocol has launched a new Pseudoplastic wire rope lubricant (Wireshield), it is designed to transform into a fluid like consistency under shear ensuring penetration. Can be applied manually or by an applicators.

Hi,

Wire rope "Grease" is a term used in the past. Grease is hardly ever used now, even though manufacturers supply thixotropic range and like to call it 0, 00 or 000 type.

ISO VG 32 is probably the ideal viscosity for such applications.

There are many different products that you can use to lubricate wire ropes but the key is to use the right equipment to apply. You need a pressure lubricator that cleans off the rope, forces new grease into between the strands and forces out wear debris, dirt and water. You want excellent corrosion protection, good water washout resistance, good EP characteristics and good resistance to oil separation. The list goes on. Ones that dry on the surface are not likely what you want. Many companies make these lubricators like Kirkpatrick.

I think elba OGL 00 and other product Elba Grease wire rope is very good can solve your problem

hi bubun.
u can also go for KLUBER range of products. We have a brand named OKS which is well established in market. OKS 450 is the product for wire ropes.
For kluber products u can contact me at :

shubrajit.bhaumik@in.klueber.com

EVERYONE IS LOOKING AT THE LUBRICANT THE APPLICATOR CAN MAKE ALL THE DIFFERENCE AND A GREASE IS THE ANSWER BUT YOU MUST HAVE AN APPLICATOR THAT IS DESIGNED TO PUSH THE LUBRICANT INTERNAL TO THE WIRE ROPE WHERE ALL THE DAMAGE TAKES PLACE IF THERE IS NO LUBRICANTS PRESENT AT THE CORE. iF YOU ARE INTERESTED CALL 901-257-9257

IS ANY ONE INTERESTED IN AN APPLICATOR DESIGN TO FORCE LUBRICANT INTO A TWISTED WIRE CABLE? E-MAIL ME AT JOELTROSS@AOL.COM

Initially appearing as a translucent amber gel this Wire Rope Lubricant is designed to transform into a fluid like consistency under shear. This transformation eases application and improves penetration to the rope core.

Ive spoke to a customer who uses a solvent based product to penetrate and a heavy/tacky products to seal. Not sure what the results were. Also depending on the core you may want to use different lubricants.

Pressurized applicators is an investment that not everyone is able to justify but it seems to me that would be the best rout.

Elba Lubrication has very good product for Wire rope it is called OGL 000. best product so far on wire lubricants www.elba-lubes.com
