  • Publication number: 20210040750
    Abstract: A cage assembly configured to raise and lower with respect to a container which has an opening closed by a hatch cover. The cage assembly comprises a rail structure having a proximal side, a distal side, and first and second ends defining a generally rectangular enclosed area in which a worker can stand. The rail structure further defines an opening in the proximal side so that a worker can access the enclosed area. Moreover, the rail structure further comprises a plurality of parallel rails including a top rail and a lower rail, with the top rail having a generally rectangular configuration to define the enclosed area. A respective bump out is defined by the rail structure on at least one of the proximal and distal sides thereof to facilitate opening of the hatch cover. The bump out is formed at least in part by a configuration of the lower rail.
