	Partially Automated Work Station Crane with Cantilevered Supports Aids Welding Ventilation Without Workflow Interruption
	A metal fabrication shop in Illinois was having a problem with excessive exhaust in a welding area with two robotic arms. Most options for ventilation in these work cells involved the construction of walls or partitions which restricted traffic flow near the workspace. Other ventilation systems filtered the ambient air and would not effectively ventilate the majority of the exhaust produced by the welding. In order to meet their requirements of better air quality for employees and unrestricted work flow, the company contacted their material handling provider, Handling Systems, Inc.

	The Frommelt Safety Solution: We explored the concept of incorporating our Frommelt Fume extraction systems with a Gorbel work station crane. One of the challenges they faced was that the loading and unloading of raw materials to this work cell is done using an overhead crane. The final solution was a freestanding work station crane with a 900-pound Frommelt fume extraction hood secured between two steel bridges with tractor drives. The system spans both welding work cells, and has push button controls on both ends to engage the tractor drives and move the hood over the desired cell. Limit switches signal to the tractor drive when the hood is in place and stops the movement.
	To accommodate for the flow of materials in and out of the work cell, the work station crane has cantilevered supports on each end to enable the existing overhead crane to continue to deliver products to the work cell.

Frommelt Side to side retractable weld curtains were added for flash protection and easy entry into cell area.

The cell dimensions are 13' x 8' and weld curtain size is a retractable 20'w x 4' H.
