Aspects of the disclosure relate to a clutch assembly for handling a container, and an associated method for using the clutch assembly. The clutch assembly includes a shaft configured to rotate in a first direction and a second direction, opposite from the first direction. The clutch assembly further includes a clutch coupled to a first end of the shaft. The clutch includes at least two rollers configured to move into a first position, extending radially beyond a periphery of the clutch, and out of the first position, extending radially flush with or inward from the periphery of the clutch.

A coupling system for lifting a heavy load comprises a male part lockable to a female. The male part has a frame, a locking pin longitudinally movable with respect to the frame in a locking direction and a plurality of latches, which are movably connected to the frame and arranged around the longitudinal axis of the locking pin. An outer side of the locking pin and inner sides of the latches cooperate with each other such that upon moving the locking pin in the locking direction along the inner sides of the latches, the locking pin pushes the latches outwardly in a transverse direction of the longitudinal axis from retracted positions to extended positions of the latches. The female part has a hole surrounded by a rim, which allows the latches to penetrate into the hole in their retracted positions and behind which the latches hook in their extended positions.

A grid framework structure includes a first set of parallel rails or tracks and a second set of parallel rails or tracks extending substantially perpendicularly to the first set of rails or tracks in a substantially horizontal plane to form a grid pattern. The grid is supported by a set of uprights to form a plurality of vertical storage locations beneath the grid for containers to be stacked between and be guided by the uprights in a vertical direction. A load handling device includes a body mounted on a first set of wheels and a second set of wheels arranged to engage with the tracks. A gripper assembly is provided for latching to a storage container via a deformable flexure mechanism movable between a locked configuration and a release configuration.
