A dumbwaiter is often used to transport materials from one floor to another in a home or commercial building. In fact, products like Jeeves have specific home and commercial dumbwaiter models. Commercial models, in particular, are common in multistory restaurants as a way to get dishes and food from floor to floor. Typically, dumbwaiters range in support capabilities from 75 to 500 pounds, with the latter being the largest type of commercial model on the market. If you’re looking for a dumbwaiter to add to your home or commercial building, here are some qualities to look for:
• A motorized design. Many use a winding drum or machine traction drive mechanism like an elevator.
• An LCD display that indicates its current operation.
• UL certification. At the moment, Jeeves’ models are the only ones on the market with this type of certification.
• A rail or trolley system with slack cable safety brakes.
• A cab that is already wired and setup to reduce installation time.
• Shelves inside for a food service dumbwaiter.
Most dumbwaiters are made from steel or wood. Dumbwaiter cabs used for food service must be made of stainless steel. The cabs should be able to move at 30 feet per minute and be powered by 115 volts. Larger models may need more power, however. Additionally, most dumbwaiters have some safety mechanisms, such as a slack cable, a final limit, a trolley brake, and an interlock door.
Commercial dumbwaiters vary between capacities of 125 and 500 pounds. Some are designed for traveling 70 feet total and to go seven stops. Those specifically for food service typically have shelves inside for support food and dishes. In all cases, however, a dumbwaiter is only used for objects – no person should ever attempt using one as an elevator.
