For People With A Disability
Special electronic shopping carts are provided by many retailers for the elderly or people with a disability. These are essentially electric wheelchairs with an attached basket. They allow customers to navigate around the store and collect groceries.
Manually powered trolleys are also available specifically designed for use by wheelchair users. A still to be implemented aid for people with disabilities is the addition of a guide wheel at the centre of rotation of a trolley with 4 caster wheels. In order to allow the nesting of trolleys to be unhindered this guide wheel is attached to the front of the trolley with a piece of spring steel which bends under the cart's weight.

Famous quotes containing the word people:
“Our young people have come to look upon war as a kind of beneficent deity, which not only adds to the national honor but uplifts a nation and develops patriotism and courage. That is all true. But it is only fair, too, to let them know that the garments of the deity are filthy and that some of her influences debase and befoul a people.”
—Rebecca Harding Davis (1831–1910)
