7. Effer cranes have greasing points to keep them efficiently operating and to preserve moving parts over the years. A central greasing system is available as an option to simplify maintenance operations, granting sure oversight of the whole crane.

8. All our cranes take advantage of a control valve with internal compensation. With this solution, it is possible to carry out simultaneous movements. For this purpose we benefit from the cooperation of worldwide producers (Hawe and Danfoss).

9. Effer cranes rotation bearing is equipped with a leaktight seal between the rotary rings, to prevent water and dust entering the tracks. All Effer rotation bearings are fastened by means of high resistance screws tightened with a dynamometric wrench. Effer rotation bearing uses two circles of ball bearings to reduce the rotation friction to a minimum.
