RETRACTABLE TOP COVERING MECHANISM

摘要

A retractable top covering system has a top covering configured to cover an open top area of a container having sides that define an interior space. The top covering is connected to a retractable top drive mechanism that selectively retracts and deploys the retractable top covering. A track is supported along an upper edge of the container around a portion of the open top area. The track supports at least one trolley for relative movement along the upper edge of the container. A support bow is connected the trolley and supports the retractable top covering. A cable, connected between the retractable top drive mechanism and the trolley, moves the trolley along the track in response to retraction and deployment action of the retractable top drive mechanism.
