There are basically three types of elevators most commonly found in public buildings: mechanical, automated, and electronic. There are also variations of each type, however; there are various types of hydraulic elevators. Hydraulic elevators, also called water-powered elevators, are powered by a piston located at the base of the elevator which pushes the elevator upward via a series of moving parts. As the piston rises, a drum (or bell) drums motion inside a cylinder, sending a signal upward to a connecting rod at the top of the elevator. The height of an elevator is determined by the force of gravity acting on the drum. This type of elevator is frequently found in office buildings, restaurants, and shopping malls and requires regular maintenance by professional elevator maintenance companies in Dubai.
Another common type of elevator in a commercial building is the mechanical elevator. Mechanical elevators use a pulley system that can be controlled manually or by a remote control to move an elevator from one floor to another. These elevators are commonly found in machine rooms where multiple levels of machines are located. Hydraulic lifts, like the hydraulic machine room elevators, can only be operated by a qualified technician trained by a professional elevator company like Orona elevators, who must be given special training for this occupation.
Types of electric elevators include: chain-drive, rack and pinion, screw drive, and screw-driven. Electric elevator types generally consist of a shaft attached to the engine or a generator, which raises and lowers the machine. Most of these elevator types use a tension spring, cable, or chain to raise and lower the machine; however, some elevator types use a single, constant tension spring that requires no manual lifting. All elevator types provide the operator with a safety mechanism that prevents the shaft from damaging surrounding surfaces and causing damage to people or machinery.
The main types of non-mechanical elevator types are: concrete, which are commonly seen in municipal buildings that need to be modernized; roller shutter doors, which are used on high-rise buildings and in commercial settings; and metal, which can be seen in airport terminals and shopping mall escalators. Each of these elevator types provides different qualities of service to its users, as well as different operating conditions. types.
