Abstract The self-levelling spreader beam disclosed, consist of a pair of slings [10] coupled to a spreader beam assembly [01,02]. Adopting the mechanical advantage of running the slings [10] through a series of roller sheaves [07, 08, 09] to reduce the capacity of actuators required for the manipulations of the slings [10]. Its unique feature is the manipulation of the exposed slings [10] to achieve an ideal effective working length, to indirectly and relatively, position the combined center of gravity of, every component under the hook, influencing it to move below the hook as the load leaves the ground. It uses an angular sensor as a feedback system, sending signals to a logic control system, which in turn, with predetermined logics and events, energize the respective actuators to, commence or stop, manipulating the effective working length of the slings [10] until the entire system comes to a state of equilibrium.I [Fig. 1] 1213 12 1-11 [Fig.2]9 09-0 -10 1 0-\ -06 -03 08- 04\ - 05 14- 02 Figure 1 [Fig. 2] 05 Figure 2
