Foreword
This article was originally written for a publication specialising in the off-highway and plant industry. Due to the opportune mentioning of VLS (Verification of Lubricant Specifications), I felt that LUBE’s readers should study this. Suzy Jarman
Lubrication for the Plant Industry
Introduction
The United Kingdom Lubricants Association (UKLA) is a legal entity, not for profit company – Trade Association, providing a collective view and position of members to Government Departments, EU Bodies, Agencies and Regulators. We provide training, education materials, technical advice, networking and publications to our members.
Representing the UK Lubricants industry, as I do, I am constantly aware of the role that lubricants play in keeping the wheels rolling for the whole of industry across Great Britain. All types of lubricant are produced by our member companies, across Industry
for a thousand-and-one applications. Working in all kinds of environments, experiencing all manner of demands and stresses, there is no better example of this reality than with the Off-Highway and Plant Industry where we know that equipment works in the harshest environments, encountering rain, dust, heat and cold where any unscheduled downtime constitutes a major management headache. At the heart of all maintenance schedules lay the lubricants which vary from basic industry standard products to specialities developed to cope with some of the toughest operations without which, equipment would self destruct.

The latest trends in lubricants are in evidence for hydraulics where multi-grade type oils are now widely used to offer year around performance. Biodegradable hydraulic oils are now required in many operations to meet environmental demands. I can testify that certain ester based products do offer very long service with low environmental impact.
On the engine lubricant front, we are also seeing the environmental demands significantly impacting on product development. Engine oils now need to be compatible with exhaust gas recirculation and catalytic after-treatments whilst bio-fuels are also becoming part of the equation – the focus for ACEA 2012 is on bio-fuel compatibility! If we include Urea solutions (AdBlue) with Selective Catalytic Reduction (SCR) to the equation, things just keep getting more and more complex. Euro 6 requirements are further calling for a reduction of emissions by half which all inevitably lead to further changes in engine lubricant formulations.
Looking at some of the specialised products required in plant operations we see specialised greases, wire rope dressings, EP gear lubricants, robust transmission fluid and open gear lubricants, all essential for dealing with lubrication under conditions of shock loading, corrosion, erosion and ingress of all types of contaminants. It’s a tough call but a challenge that the lubricants industry has always risen to.

One area of activity that has now become a must for plant equipment in service is the application of ‘Oil Condition Monitoring’ which has proved invaluable in preventing failures and optimising lubricant service life. Samples taken from sumps of equipment, in service or at oil drain intervals can give insight to impending failures by tracing increasing levels of wear materials, viscosity loss through fuel dilution or water ingress from coolant leaks. All of these can lead to costly failures, whereas timely intervention can
