Abstract
A manually-operated utility cart for carrying a removable basket. The cart has a basket support adapted to move in a vertical path to raise and lower the removable basket between desired vertical positions. The basket support is moved by means of a gear mechanism that includes generally vertical racks attached to the basket support and pinions that engage the racks and which are mounted on a horizontal shaft supported on an upright frame. The gear mechanism is manually operated by the operator using a crank arm or other similar mechanism. The basket is provided with a door on one side that can be pivoted downwardly for better access to the contents of the basket.
