What powered the original lift?

The original elevators were powered by steam.

In 1852, Otis, who was still working at the Bedstead Manufacturing Company, received a task from his employer to manufacture an elevator. Otis invented the elevator by summarizing the advantages and disadvantages of past elevators. A safety braking device.

This elevator, driven by a steam engine, uses a ratchet-like safety braking device. In 1853, at the World's Fair in New York, USA, Otis also demonstrated the safety elevator he invented. Later, Otis founded his own elevator workshop, which became the famous Otis Elevator Company in the future.

Early elevators were driven by steam engines. For example, in 1857, Otis installed the world's first safety passenger elevator for a store specializing in French porcelain and glassware. The ladder can carry 450 kilograms and is driven by steam power with a speed of 12 meters per minute. In order to power steam engines, early buildings equipped with elevators had to be equipped with boiler rooms.

In 1889, elevators began to be driven by electricity, and elevators began to develop rapidly. In 1889, the American Otis Company produced a veritable elevator powered by a DC motor. After that, elevators sprung up in various buildings and hotels in Europe and the United States.

Key points for purchasing lifts:

1: When purchasing lifting machinery, you cannot blindly purchase it. You must conduct sufficient market research and on-site inspections to determine the size and quality of your company. its credibility. This is first and foremost.

Many small-scale companies in the market cut corners in order to gain violence, thus greatly reducing the quality of lifting products. Although they sell them very cheaply, this kind of machinery does not last long and is highly dangerous. Therefore, as a buyer, you cannot be greedy for a small price advantage and cause greater regrets.

Two: Based on the information you have investigated, to choose a lifting machine with a better price/performance ratio, you should choose based on its technical parameters, practicality and versatility.

Usually there are many types of lifting machinery, including (vehicle-mounted, fixed, hydraulic, scissor-type, etc.) The technical parameters and uses of each are slightly different, but there are also many similar functions. Therefore, as a customer, you need to make a purposeful purchase, that is, what kind of lifting machinery you want to buy, and which lifting machinery can meet your needs and has many uses.

Three: The last point is that after the equipment arrives, when unpacking and accepting it, you must check whether the random technical information is complete, whether the random accessories, tools, and accessories are consistent with the list, and whether the equipment and accessories are damaged or defective, etc. , and make records of unpacking and acceptance.
