1. A carriage cart comprising
a chassis frame with a front end and a rear end; a pair of front wheels mounted on the front end of the chassis frame; a pair of rear wheels mounted on the rear end of the chassis frame; wherein each wheel comprises a lifting member pivotally mounted on a pivot at the same side of the chassis frame with the wheel, wherein when the carriage cart is moving in a travel direction running from the rear end to the front end of the chassis frame on a first surface by rotation of the wheel in a first rotation direction, the lifting member of the front wheel is projected beyond the front wheel in the travel direction, and wherein as the carriage cart is negotiating a second surface substantially perpendicular to the first surface, the lifting member of the front wheel contacts firstly the second surface, by which the lifting member is pivoted in a second rotation direction opposite to the first rotation direction, thereby lifting the front wheel off the first surface.
