Load lifting systems include a first flexible suspension member configured to attach to a load lifting structure at a first fixed connection at a first end of the first flexible suspension member and attach to the load lifting structure at a first adjustable connection at a second end of the first flexible suspension member and a second flexible suspension member configured to attach to the load lifting structure at a second fixed connection at a first end of the second flexible suspension member and attach to the load lifting structure at a second adjustable connection at a second end of the second flexible suspension member. An interconnect member extends between and connecting the first adjustable connection and the second adjustable connection. A carriage is movingly suspended on both the first flexible suspension member and the second flexible suspension member.

The present invention is a controllable hook assembly having an actuator operably connected to an arm motor assembly and a drive assembly configured to move independently a plurality of hook arms between an open and closed position capture and release a load. A controller is configured to operate each drive assembly to move the hook arms cooperating with screw threads in said actuator to provide rotation about a pivot point to drive each of the hook arms between an open and a closed position so as to allow for independent actuation of each of the hook arms.

The present invention is a controllable hook assembly having an actuator connected by a clutch to a drive assembly configured to limit the connection to a predetermined linear force applied to the actuator. The drive assembly and actuator of the controllable hook assembly also is configured to move a plurality of hook arms between an open and closed position and is adapted capturing a line attached to a load. A controller is configured to operate the drive assembly to move gear teeth in the hook arms cooperating with screw threads in said actuator to provide rotation about a pivot point, drive an actuator output shaft such that when the actuator is energized the linear motion of the actuator output shaft moves the hook arms between an open and a closed position so as to allow for repeated capture of loads by helicopter or other lifting devices without the need for extensive setup for such load capture.
