The Sweeper system is designed to automatically remove material from a gaylord or octobin type container without the need for human intervention. The motor that rotates the pick up tube is only activated when vacuum is sensed from the user's conveying system. As the unit unloads the material from the gaylord/octobin, the counterbalance system allows the motor/control assembly to lower and follow the level of the material. When the sweeper reaches the bottom of the container, there will be a small amount of material remaining, which can be easily removed with the Gaylord liner and returned to inventory.
