Figure 3. Relationship moments in balance The proposed crane in this paper reduces the ballast and eliminates the anchor, since it will be auto balancing''. The concept of self-balancing involves eliminating anchoring system, which is replaced by a movable counterweight as shown in Fig. 4. Figure 4.
