An extension arm from the internationally known brand Liebherr, as can be seen in the video, is used for moving earth, rocks, etc.
A good lubrication system on this Liebherr extension arm is key to maintenance, performance and durability, since if it did not have a good lubrication system, these 3 points would be reduced by 90%.
We observe the different lubrication points next to the pipe and other types of accessories for lubrication systems.
