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. Elevator

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 “hydro rams”. 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 “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 gear less. 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 gear less system includes alternative or direct current high-speed gear less motor which is attached to the drive sheave directly without using steel ropes.

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.
