We wrote an article that goes deeper into the differences between material lifts and freight elevators, as well as a cost breakdown of both. Both dumbwaiters and freight elevators can be difficult and expensive to work on because of the shaft housing. With manual dumbwaiters, constant supervision and labor are needed to ensure the system is operating correctly.And while the upfront cost for a dumbwaiter lift may be lower, the total cost of ownership is higher than a material lift. This means that there are mandated maintenance programs that must be adhered to. Both are governed by the National Elevator Code ASME A17.1.It’s also important to know that the industrial (or commercial dumbwaiter) and freight elevators do have similarities: The installation of this dumbwaiter is easiest if the hoist-way is properly prepared. While both are designed to move materials, a freight elevator relies on a shaft and a large motor housing (machine room), whereas a dumbwaiter relies on a hoist and wire rope lifting mechanism to move the carriage up and down via dumbwaiter shaft. This manual will cover the installation procedure step-by-step. Although these lifts are sometimes referred to as mini-freight elevators, It’s important not to confuse them with an actual freight elevator.
