As a key element of the customer’s corporate strategy, the management decided to switch one application over to a biodegradable grease. This decision was followed by an invitation to tender, in which the company wrote to various eligible suppliers – that is, lubricant manufacturers.
The grease is used to lubricate the bearing surface (main plate or fifth wheel coupling) of articulated lorries and is supplied via a central lubrication system located under the main plate, to which it is applied at five lubrication points. This bearing surface is exposed to considerable stresses due to both the semi-trailer and the effects of weather. Particularly in the event of longer service lives, the openly accessible lubrication point means that the lubricating grease can also enter the environmental cycle, as this is an example of “total loss lubrication”.
