Patent ID: 8905190

Claim:
A system for accessing a container including a plurality of attachment openings and a cooling unit, the system comprising: a pair of towers, wherein each tower has a vertically oriented longitudinal axis and includes a plurality of elongate tower sections coupled together end-to-end; a toothed rack extending along each tower, wherein the toothed rack is oriented parallel to the longitudinal axis of the corresponding tower; a raisable platform positioned between the pair of towers and configured to move vertically relative to the pair of towers; a pair of drive assemblies coupled to the raisable platform, wherein each drive assembly includes a pinion configured to mesh with one of the toothed racks and a transmission configured to rotate the pinion relative to the corresponding toothed rack; wherein each tower section includes at least one elongate recess oriented parallel to the longitudinal axis and configured to receive a first steering element coupled to one of the drive assemblies; and a plurality of support elements configured to couple the towers to the container, wherein each support element comprises: an elongate housing having a horizontally oriented central axis; an elongate rod extending through the housing along the central axis and configured to rotate relative to the housing along the central axis, wherein the rod has a first end and a second end opposite the first end; a locking member fixably attached to the first end of the rod, wherein the locking member has a profile configured to axially pass through one attachment opening along the central axis of the elongate housing in a first rotational orientation and be prevented from axially passing through the one attachment opening along the central axis of the elongate housing in a second rotational orientation; and a guiding handle coupled to the second end of the rod and configured to rotate the rod about the central axis of the housing to transition the locking member between the first rotational orientation and the second rotational orientation; and a tightening mechanism coupled to the second end of the rod, wherein the tightening mechanism is configured to move the rod and locking member axially relative to the elongate housing with respect to the central axis of the housing.
