High Speed VRC Retrieves Inventory for Amusement Park Gift Shop

A popular amusement park was in the process of updating its inventory storage and retrieval system for their gift shops.   They wanted to  better automate the movement of inventory from below-ground storage to store level almost 18 feet above. They were seeking a lift solution that could be controlled by a programmable controller (PLC) to integrate with their overall conveyor system. Based on the high volume of sales in the gift shop, the lift would need to be able to operate at the same speed as the rest of the conveyor system – 60 feet per minute. The lift would have to accommodate rather small unit loads in the smallest amount of square footage as possible. Finally, because the critical nature of this inventory system, the lift would need to operate with an extremely high level of reliability and a minimum of down time.

The technical sales team at Autoquip met with the engineers at Disney to clarify all equipment specifications, installation constraints, and applicable code requirements. A low-capacity vertical reciprocating conveyor (VRC from our Freightlift family of mechanically-actuated VRCs was identified as the best solution for this application because: 1) lift is extremely robust and reliable, 2) lift is easily customized to accommodate higher operating speeds, and 3) lift is most readily able to be programmed with the use of a PLC.

Each lift was equipped with a chain-driven live roller (CDLR) conveyor section and photo-sensing switches that automatically tracked the location of pallets as they entered and left the lift, activating lift and conveyor motor controls accordingly. And finally, the lift was designed with special 2-piece spliced guide beams that would be able to be handled and installed in the limited/small space allotted for this lift, then attached end-to-end in the field and field-welded to provide a smooth and seamless guide path throughout the 18-foot travel. Disney has been completely satisfied with this reliable and programmable material lift solution, and regulatory agencies in the state of California have certified the lift as being adequate for use in a seismic zone.
