- The safety of the operational people is highly increased because they don’t have to climb the grab to grease it. The height of the grabs in open position is often 5 to 7 meters.
- It saves a lot of time, because about 15 greasing points are connected to one central point.
- The lifetime of all moving parts is increased, because of better greasing and thus less wear.
Normally each articulation point has its own greasing nipple and must be greased individually. The central greasing system connects all greasing points of the grabs upper part to one central greasing point at the inner side of the arms. The system is completely built inside the grab construction and is therefore very well protected against damage through collisions.
The whole grab can be greased without having to climb the upper structure.
