The manual control for the front wheels of a shopping trolley is composed of an assembly of rods and tubes (2/6,3/6,4/6,5/6,6/6). These are welded onto the trolley and connect the front wheels to the control handles positioned near the basket handle. There are right and left control handles and two vertical control transmission rods protected by a tube. There are two horizontal rods with a junction mechanism between them and the vertical rods. A front tube allows coupling turning of the front wheels.
