Elevators - Top 4 most used types of Home Elevators

Some people are thinking that installing an elevator is luxury and some people, necessity. If you are one of those who think that means luxury, it's all right; I'm not saying that installing home elevators is a must. At least that you can do is to read this article and maybe you'll learn something new about the lifts. If you are one of those who think that means necessity I want to tell you some details about the most used types of elevators for home appliance.

The most used types of home elevators are: hydraulic elevators, electric (traction) elevator, pneumatic lift elevator and overhead winding drum. Hydraulic lifts are the most secure and the most used home elevators. These lifts are operated by hydraulic rams also known as a "hydrams". They are pumps that cycle the water, supplied by hydro-power.

There are a few types of hydraulic elevators, known as "roped-hydraulic", "hole less", and "in ground". "In ground" systems must have a huge hole at the lowest level of the house and has to be drilled down, with depth same as the length of the lift trajectory. That's because the cylinder is moving down through the hole as the cab is moving up. Sometimes there are no possibilities to drill this hole. In that case are using so called "hole less" systems because on each side of the elevator they are using a pair of hydraulic jacks as a moving force. Roped-hydraulic system is alternative when it's not possible to drill hole for the cylinder and the cab travel is greater than the "hole less" systems can provide. They are combination of hydraulics and ropes connected to jacks, controlled by friction governor and governor-tension sheave.

Electric also known as traction elevators have two types of traction systems. The traction systems can be geared or gearless. The geared systems can be power supplied by alternative or direct current. Geared machines are using to control the moving of the cab. The cab is connected by big steel ropes and they are rolled by high speed motor over drive sheave. The gearless system includes alternative or direct current high speed gearless motor which is attached to the drive sheave directly without using steel ropes.

The third type is the pneumatic elevator. These lifts can carry only one or two people and their cab is moved by pneumatic system by creating air pressure difference between the top and the bottom of the cylinder tube. No cables, no pistons and no pulleys, just like the elevators in the "sci-fi" movies. The aluminum and glass are the only materials used in the process of manufacturing of these residential lifts.

The last of the four types is overhead winding drum elevator. As we can assume from their name these types of residential lifts, an overhead winding drum is used to manipulate with the elevation cab, so there's no need for machine room because the winding drum machine is placed at the top of the elevator hoist-way.

I hope that this information was quite helpful for you and as a potential buyer you've got some clarifications about the types and subtypes of home elevators. I'm sure that you'll make the right choice and you'll install the most suitable elevator, according to your requirements.
