Dumb Waiters


A dumbwaiter is a small freight elevator (or lift) intended to carry objects rather than people. Dumbwaiters found within modern structures, including both commercial, public, and private buildings, are often connected between multiple floors. When installed in restaurants, schools, kindergartens, hospitals, retirement homes, or in private homes, the lifts generally terminate in a kitchen.

The term seems to have been popularized in the United States in the 1840s, after the model of earlier ‘dumbwaiters’ now known as serving trays and lazy Susans. The mechanical dumbwaiter was invented by George W. Cannon from New York, who first filed for the patent of a brake system (US Patent no. 260776) that could be used for a dumbwaiter on January 6, 1883. He later filed for the patent on the mechanical dumbwaiter (US Patent No. 361268) on February 17, 1887. – From Wikipedia

Harmar DW100 Ascent Dumbwaiter

Unlike other dumbwaiters that are built like mini-elevators—with complex pulley systems, guide rails and traveling control cables—the Ascent comes complete. The entire drive system is pre-installed on the underside of the car, with the car’s chassis/trolley pre-installed on a section of the track.

On-site installation is as simple as connecting sections of track, securing the drive cable to the header, and wiring the controls and interlocks. That can cut up to a full day of installation time compared to other dumbwaiters.

The proven Ascent drive train system rides on a single extruded-aluminum track to eliminate the time and cost of assembling complex multi-channel rail systems. Plus, the simplified wiring of the cable-drum drive system is an integral part of the car.

The Ascent offers superb performance for years to come. No wonder we can guarantee it with the best warranty in the business.
