Cart wheel locks, often used by large retailers to prevent theft, typically employ an electronic system activated by a perimeter wire. Here's a breakdown of how they work:
-
Electronic System: The core of the system is an electronic wheel clamp or "boot" attached to the shopping cart wheel.
-
Perimeter Wire: The store's parking lot is fitted with a thin wire embedded in the pavement, creating an electronic boundary.
-
Activation: When a shopping cart with the electronic wheel clamp crosses this wire, the clamp is triggered.
-
Locking Mechanism: Once triggered, the electronic clamp locks the wheel, preventing the cart from rolling any further. This deters customers from taking the cart beyond the designated area.
In essence, the cart wheel locks work by creating a virtual fence that, when breached, disables the cart's mobility through electronic activation of a wheel clamp.
