Electric Dumbwaiters

Dumbwaiters are similar to a freight elevator, but are a lot smaller than what most people think of when considering an elevator. These devices are, unlike regular elevators, not designed for people, but instead are designed for moving inanimate objects in between the floors of a building. Using a dumbwaiter makes it a simple t task to move your household supplies in between floors.

The dumbwaiter has rich roots in American History and today many people decide to retro-fit their home with a dumbwaiter. In order to have room for a residential dumbwaiter, it is necessary to have a shaft that rises vertically between floors. The exact size of the shaft will depend on the type of dumbwaiter you use, but most require a shaft that is 4 foot square (2′ x 2′.) Most can be configured to be opened on different sides at every stop, so this makes finding a space for them much easier.

Today, most lifts are electronically powered and use a track system. The track runs the length of the shaft and the dumbwaiter car moves along the track. While dumbwaiters in homes are very popular, they are even more so in commercial businesses. Many manufacturers make use of them to connect the various parts of a plant. This allows them to make better use of their building and greatly improves their productivity. They are often used in hospitals, car manufacturing plants, and department stores. Many restaurants also use them to reduce the amount of staff required to run the businesses.

Usually a modern dumbwaiter does not require any excessive maintenance. One of the most important maintenance tasks is the lubrication of the track. This keeps the car moving safely and steadily. Often, as is also the case with automobiles, paying attention to the sounds the dumbwaiter make can be essential in determining its mechanical state. If the lift begins to make any unusual noises, this can be a sign that it needs lubrication.

It is also important to keep the car clean. If something is spilled, it should be quickly cleaned and it is important to make sure nothing falls down the shaft. Most lifts feature safety doors, which only can be opened when the car is present. This prevents things from being dropped down the shaft or falls. It is imperative to never disable this safety feature.

In addition to the safety doors, most modern lifts usually also include sensors built into the car. As the car moves along the track, the sensors will stop the car from moving if something in the track is present that could hurt the car.

Choosing to install a dumbwaiter in your home or business is often the first step in improving productivity. Their popularity has greatly increased over the years, since they were first developed over a thousand years ago.

What is a Commercial Dumbwaiter

Dumbwaiters are a type of elevator that is intended to transport goods instead of people. In residential settings, these devices typically support around 150 pounds. Commercial dumbwaiters able to support much more than this, with some supporting well over a thousand pounds.

Commercial dumbwaiters have been used extensively in businesses since the eighteen hundreds. During this time, they were most popular among large manufacturers who needed to be able to quickly and easily transport items from one part of the production stage to the next. Today these devices are found in all types of businesses, including restaurants, hospitals, libraries, mines, and even regular office buildings.

Commercial dumbwaiters offer several advantages over traditional dumbwaiters. They are able to not only support more weight, but the also frequently have special features that are designed to help improve the utilization of space in the dumbwaiters car. For instance many include a complete shelf system inside the car and improved call controls that can tell you exactly where the dumbwaiter is located. The call controls of a commercial dumbwaiter are also much more advanced and able to prioritize its travel, much like a regular elevator, based on the order that buttons are pushed.

The early dumbwaiters, had relied on simply a rope and some pulleys. Quickly this proved to be unreliable and so during the eighteen hundred, manufacturers began using a track system in their dumbwaiters. The track is installed the length of the track and the dumbwaiter is attached to this track. This keeps the dumbwaiter level and stable, but also helps to improve safety.

Modern dumbwaiters have built in brakes, which stop the dumbwaiter from moving in the event of a cable failure. The brakes will physically lock onto the track and hold it in place until it can be serviced. They are also designed with many sensors to detect objects that might obstruct the travel of the lift. If something is stuck in the shaft, the dumbwaiter will detect it and stop, so there is no concern about damaging the lift.

Commercial dumbwaiters are found in almost all industries. From car manufacturers to cruise lines, dumbwaiters are there improving work flow and cutting the costs of doing business. These devices can greatly improve functionality and not only do these devices cost less than regular elevators, since they are not rated to carry people, the building codes are not as strict when installing a commercial dumbwaiter.

Residential Dumbwaiters

Dumbwaiters are devices, similar to elevators, which have been used for over a thousand years. The earliest recored dumbwaiter dates back to 236 BC during the Roman Empire. Their popularity has only increased since then and today they are found in many peoples homes and businesses.

While the residential dumbwaiter has always been popular, commercial dumbwaiters were much more common. Businesses of all types use them to help make it easier for their employees to work. They are common in restaurants, libraries, manufacturing plants, boats, and many other commercial settings.

Dumbwaiters were also consistently found in almost every multi-level home, until the 1930’s. Their popularity slightly decreased at this time, but they were still used extensively in larger homes. Until very recently, they were still consistently found in large homes, but few mid-sized homes made use of them. However, this has changed in the past ten years as the price of dumbwaiters has dropped, while the quality has increased.

The electric dumbwaiter is the most popular type found today, but some people still do opt for a manual dumbwaiter. One of the reasons that dumbwaiters are more reliable today, then a hundred years ago, is that they almost always use a rail system. The rail, or track, is installed along the length of the shaft and the dumbwaiter car is attached to the rail. This keeps it even and steady as it moves between floors.

For residential settings, most dumbwaiters support at least a hundred pounds. Some manual dumbwaiters and a few electric dumbwaiters support less than this, but usually a hundred pounds is the minimum amount of weight you want to support, because it can quickly add up. Most electric dumbwaiters can also be upgraded to support more weight, sometimes over two hundred pounds and dumbwaiters used commercially can support even more.

A residential dumbwaiter is most easily installed into a home as it is being constructed, but it is also possible to install them into an existing structure. The one major requirement is that there is a vertical shaft between floors. To improve the flexibility of the device, most can be configured to open on different sides. So you could have it open on one side in the upstairs hallway and another in the kitchen. This increased flexibility, greatly improves their ability to be added to an existing home.

While there are several kits available that can be installed by the homeowner, they do require a strong amount of technical knowhow, so it is often a good idea to go with a professional installer.

After a dumbwaiter has been installed in the home it will provide numerous years of dedicated service, but it is important to properly maintain the device. These mini-elevators make it possible for people in homes all across America to easily move goods between different floors. They help to reduce the amount of work around the home and how much time it takes, because it is possible to quickly move laundry, groceries, and other objects around the house. They also help increase home value, which in todays market is more important than ever.

Dumbwaiters Through the Ages

The modern dumbwaiter, which today usually uses electricity, has roots that date back many hundreds of years. These early dumbwaiters laid the framework for today’s electric dumbwaiter.

In ancient times, dumbwaiters were often used in large castles and other dwellings that spanned multiple levels. In castles, this allowed the servants to quickly and easily move food or other supplies around the castle. Without them, the kings food could become cold before being brought to him. Also many castles had very long and winding staircases, which made carrying anything up them both difficult and dangerous.

Typically manual dumbwaiters were used, but in some cases an animal or water power was used to lift the dumbwaiter car. Even the manual lifts made use of a pulley system, which allowed items to be sent quickly between floors, while requiring less physical effort.

By the middle of the eighteen-hundreds, the dumbwaiter was used in many businesses and homes throughout the country, but much of the innovation for these devices took place in New York. It was here during the industrial revolution that the first passenger elevator would be developed, as well as hydraulic dumbwaiters and steam powered dumbwaiters.

The father of the elevator, Elisha Otis, was responsible for many of the advances in dumbwaiter and elevator technology. While overseeing the construction of a large manufacturing plant, Otis was subjected to several dumbwaiter failures. All it took was a broken rope and the dumbwaiter would come crashing down, sometimes seriously injuring a worker or destroying supplies.

Otis set out to solve this problem and devised a spring loaded brake system. In the even of a rope failure, a set of spring powered spikes would be released. The spikes would be propelled into the dumbwaiter shaft, which would prevent it from falling. This solved his problem, so he went back to supervising the construction of the facility.

After the facility was complete, Otis was prepared to head to California to do some gold mining, when he was approached by someone who was interested in his dumbwaiter brake system. Being a shrewd businessman, Otis realized that his invention had great potential and he began manufacturing commercial dumbwaiters. Over the next thirty years, Otis would be responsible for many advances in elevator and dumbwaiter technology and eventually developed the first passenger elevator.

Otis was not the only one that led innovation during this time and together with several other inventors, the electric dumbwaiter would take shape. By the beginning of the twentieth century, electric dumbwaiters had become much more common. Although for very heavy loads, the hydraulic or steam powered dumbwaiter was usually used.

Dumbwaiters would also remain very popular in homes for much of the twentieth century. With the development of apartment buildings in large cities, like Chicago and New York, during the 1920’s, a need to easily moves goods between floors developed. This resulted in almost all buildings in large cities containing some form of manual or electric dumbwaiter.

Today, the electric dumbwaiter is very popular not only in businesses, but also in homes. Dumbwaiter kits can be used, which can be fit into most existing homes, and can be installed quickly. Custom built electric dumbwaiters are also very common, offering the advantage of better space usage and more features.

While the electric dumbwaiter is more common, some people still opt for a manual dumbwaiter. They do not offer the same convenience or lifting power that is offered by an electric dumbwaiter, but are less expensive and can be built by a handyman.

Creating a Safe Commercial Dumbwaiter

A dumbwaiter is used in many businesses today. They provide a means of moving goods throughout a building quickly and easily. With a history that dates back thousands of years, the dumbwaiter has long played an integral part of the business world.

Some of the earliest commercial dumbwaiters were used in construction. They were heavily used during the construction of buildings in New York and other cities. In fact, it was on a construction site that the idea behind the safety elevator was born.

Elisha Otis, who is often called the father of the elevator, was always a tinkerer and mechanic. After working as a mechanic at a bed manufacture for several years, he was given the opportunity to oversea the construction of a new manufacturing plant. Dumbwaiters were used extensively, but they presented some safety concerns, which largely revolved around the dumbwaiter rope breaking. A faulty rope would cause the dumbwaiter car and whatever it was carrying to come plummeting to the ground. At the very best, this would result in lost productivity and damage to property, but it could just as easily cause great harm to the workers.

Otis decided to develop a way of preventing these accidents and developed a safety device that stopped the dumbwaiter from falling. Large spikes were placed on the top of the car and kept in place with springs. In the event of a rope or cable breakage, the springs would be instantly released and forced into the dumbwaiter shaft. This would stop the car from falling and helped to prevent accidents.

By the time the construction of the factory was complete, other businesses had taken notice of Otis’s invention. He began manufacturing lifts for other businesses and eventually would go on to invent the first passenger elevator and was a pioneer in the industry, developing many innovations that are in some regards still used today.

Today, dumbwaiters still usually incorporate a safety device to prevent falls, but they do not us the spike stops. Instead, a track system is usually used and breaks are used to lock onto the track in the event of an emergency.

The dumbwaiter is used in many industries and remains an integral part of many manufacturing plants. They are also used in hotels, hospitals, restaurants, and libraries. There are many cases where a dumbwaiter can greatly improve the work process of employees, so they are often used to reduce labor costs.

Another advantage is that they are sometimes held to lower standards in regards to city and state zoning laws. Since it is not used to lift people, they often require less paperwork than an elevator would, but this depends on the city and the state, so it is very important to always check your zoning laws before installing a commercial dumbwaiter.
