Shopping cart conveyor

A shopping cart conveyor is a device used in multi-level retail stores for moving shopping carts parallel and adjacent to an escalator. Shoppers can load their shopping carts onto the conveyor, step onto the escalator, ride the escalator with the cart beside them and collect the cart with the contained merchandise at the next level.[1]

While inclined moving walkways can be used in multi-level retail stores to transport shopping carts between floors, they are associated with safety hazards (such as, with baby strollers)[1] and take up about twice as much floor space as a separate cart conveyor system, because moving walkways can not be installed at inclinations greater than 12 degrees, while a cart conveyor can operate at an inclination of up to 35 degrees.[2][3] Only specially-designed shopping carts can be transported with a cart conveyor.

Principle of operation

When the user wishes to operate the device, they push the shopping cart through the device's safety doors. Guides in the floor then direct the shopping cart's wheels into the proper position. The device then senses the presence of the cart and pulls it up to the next store level.[1] Devices generally feature some sort of a system, such as one-way hinges[1] or a sensor,[4] to stop people from entering the device.

The shopping cart conveyor operates at no greater speed than its adjacent escalator for people. This allows customers time to load their carts onto the device, ride the escalator and retrieve the cart at the next level.[1][4]

The device can only be operated with compatible shopping carts, that have mechanical features to allow them to be inserted into and moved by the conveyor.[4] During the transport, the shopping cart remains level to stop the merchandise from falling off the cart.[3]

Regulation

Shopping cart conveyors are regulated under the ANSI B20.1 Safety Standard for Conveyors and Related Equipment in the United States[1] and under the directive 98/37/EG in the European Union.[5]

gollark: Anyway, desirable properties of the number assignment system are: idempotence, and allowing you to move channels while retaining number. This is NOT possible with multiple per guild as far as I can see.
gollark: Ah, well, problem is that if it's in TWO places with an epicbot bridge there *may* be infinite loops.
gollark: I could also eventually refactor it to allow two, I think the obstacle is just the numbering mechanism.
gollark: Possibly. I like <#733816666089062511> being phones more, for now.
