A company specializing in vacuum heat treating were looking for a solution to increase their efficiencies when loading a furnace. The furnace is a 36’ long car bottom design, the transfer car is loaded outside the furnace and once loaded is moved into position. The product for the furnace is stacked on the transfer car, the lift tables serve as work platforms elevating the production team as the product is stacked, and lowers them as the product is removed after heat treating. There is a pre-existing obstruction on both sides of the transfer car frame which prevents the lift tables from being installed adjacent to the car.
