Maintenance 6.1-5 6.1-5 Lubrication

The following maintenance and care instructions apply to all CRANE POWER / PALFINGER MARINE cranes. Therefore this chapter includes also hints which do not refer to your crane.

Deficient or incorrect lubrication causes increased wear out and consequently unnecessary repairs (downtimes) of the crane. Therefore, make sure that bearings, hydraulic extendable arms and mechanic support arms are always sufficiently lubricated and that only those lubricants are used which are included in the specification below or correspond with them.

Lubricant to be used:

To lubricate the bearings only use solid-free grease without any graphite, MoS2, etc. Using different greases quickly leads to b damages on the crane.

6.1-5 Maintenance

How to grease the bearings on the crane correctly:

Before greasing clean the spot thoroughly, yet dirt that gets into the bearing hole together with the grease causes quick wear-out of the bearing.

Then press fresh grease into the bearing on the intended grease spots (oil holes etc.) until it comes out off the bearing.

After greasing it is necessary to clean off any excess grease from the bearing.

Grease the column bearing properly (rack track, thrust washer)

Before greasing the column bearing extract the main boom completely (outer boom remains folded) so that the grease may distribute evenly in the column bearings. The column bearing has to be lubricated on the grease spots intended for this by CRANE POWER / PALFINGER MARINE. If you lubricate via central lubrication make sure that sufficient lubrication is provided anyway.

After having pressed grease into all grease spots for the first time, slew the crane round its whole slew area. Then repeat this process until the grease comes out between crane column and crane base.

How to grease the hydraulic boom extensions on the crane correctly:

Extract the hydraulic boom extensions completely and then place the load-bearing arm on a piece of wood.

Before lubricating clean the grease spots off any old and dirty grease and other dirt.

Then apply the grease on the bottom of the hydraulic boom extension using a suitable tool (brush or similar).

Retract the hydraulic boom extensions while applying light pressure (lower main boom).

Then remove the excess grease.

Because of danger of slipping excess grease is a safety hazard and must not get into the environment.

Maintenance 6.1-6

If the crane has not been used for a period of time, the complete crane system must be lubricated according to the lubrication plan.

Each exposed metal part must be protected with an anti-rust agent.

All of the hydraulic cylinders must be retrieved as far as possible.

The cable winch and cable must be protected with an anti-rust agent. For continuous swivelling equipment the gear drive, pinion and all exposed metal parts must be especially protected against corrosion.

As grease is lost at most lubrication points on the work platform (grease is consumed or goes into the environment), we recommend the use of biodegradable greases.

Care of extendable cylinder piston rods:

If the extendable arms are never completely retracted to the transport position the extendable cylinder piston rods may suffer oxidation. The extendable cylinders (extendable arms) must therefore be completely retracted once a month.

6.1-6 Hydraulic oils

When choosing the hydraulic oil, you should consult your service representative.

HLP / ISO hydraulic oils should be used with the following properties:

Reasonable viscosity / temperature properties.

Good thermal and mechanical resistance.

Significant ageing resistance.

Good corrosion protection properties.

Adequate cold-flow properties.

Adequate lubrication effect at the lubrication limits.

Good air-separation properties.

Perfect foaming behaviour.

Neutral with respect to seals and hydraulic hoses.

6.1-6 Maintenance

As the viscosity of hydraulic oils is strongly influenced by temperature changes, compromises during their selection cannot be avoided. The following limiting values are valid for your CRANE POWER / PALFINGER MARINE work platform:

O pe ra tin g lim its

R ec om m en de d ra ng e

ISO Reference temperature Temperature °C

High temperature range:............... ........................................................... 10 cSt Cold start limit: .............................. ........................................................... 1000 cSt Cleanness class: .......................... ........................................................... 15/12 (according to ISO 4406)

The working temperatures differ according to the different product bases:

Mineral oil based oils: ................... ........................................................... approx. -30° C to +80° C Biodegradable oils: .......................Fully synthetic esters:......................... approx. -30° C to +80° C Biodegradable oils: .......................Natural esters:.................................... approx. -20° C to +80° C Biodegradable oils: .......................Oils on the basis of rapeseed oil:....... approx. -20° C to +65° C

Rape-seed oil and Class HLP 22 oil must not be used. Rape-seed oil causes the valves to stick!

The ideal working temperature for hydraulic oil lies between 30°C and 60°C.

If these temperatures are frequently exceeded when using the work platform, consult your service representative with regard to the installation of oil cooler or a larger oil tank.

Maintenance 6.1-6

Biodegradable oils are better for the environment than conventional hydraulic oils.

Anyway, even these oils must not be disposed into nature.

Releasing oils (including biodegradable oils) into the natural environment is not permitted!

The hydraulic oils listed in our recommendations may be blended together but must not be mixed with other fluids.

Note the following disadvantages:

Shortening of service life, Mineral-oil mixtures are not biodegradable.

Reduced permitted operational temperature for mixtures with rapeseed oil or native ester.

6.1-7 Maintenance 6.1-7 Oil change / oil maintenance

The annual maintenance of oil can significantly increase its working life. Apart from the saving in costs, this means a drastically reduced amount of waste oil and less contamination of the environment.

All rams must be fully retracted when changing the oil or topping up the hydraulic oil.

Oil maintenance means:

Filtration, dewatering and testing of the oil purity which you have carried out in an authorised workshop.
