The LaborSave automatic sack emptying system begins with the loading dock where the full pallets with sacks are placed into the system by the fork lift. The entrance to the loading dock crosses an invisible safety barrier which recognizes that the pallets are being placed in the system. The lifting of the sacks does not begin until the path is clear, showing that no foreign objects are within the lifting area.
The safety barrier acts as a safety override for the entire system, and can shut down the entire process within several milliseconds upon a foreign object penetrating the barrier.
This high level of safety (category 4) is available only with LaborSave, and is one of the many reasons that the LaborSave is accredited by every international standards agency.
