Abstract: A spray coating machine and process accommodates coating pans of various sizes and simplifies cleaning after particulate material in the pan is coated. A selected pan is supported on a trolley carried by a wheeled cart. After the cart is positioned adjacent the coating machine, the trolley and pan are extended into the machine, and then the pan lifted for support by a rotatable drive shaft and castors. The trolley is then removed from the machine, and the door is closed so that the coating process can commence. When coating is complete, the door is opened, and the trolley extended into the machine under the pan and raised for removal of the castors. Then, the trolley and pan are withdrawn from the machine. The trolley does not need cleaning after spraying, since the trolley is outside the machine during spraying of the coating solution.

Abstract: A lift assembly adapted for large vehicles includes first and second lift platforms selectively raised and lowered relative to a base member. Fluid actuated support arms are interposed between the lift platforms and the base member to define a generally trapezoidal arrangement. Segmented bearings are interposed between opposite ends of the support arms and the lift platforms and base member to accommodate tolerance stackup. The lift assembly also includes a sensing assembly that determines if a height differential exists between the lift platforms. If a height differential is sensed, movement of one of the lift platforms is altered to correct the situation. If too great a differential is sensed, further movement of the platforms is terminated. A locking arrangement maintains the lift platforms elevated relative to the base member. A sensing arrangement determines whether the locking arrangement is properly oriented and whether the load is applied from the lift platforms.
