A passenger elevator has a completely closed lift car that travels vertically within a specially prepared lift shaft. Passengers are transported between floors at reasonably quick speeds and the control systems are often designed to give the most efficient distribution of passengers throughout the building. The passenger elevators are best for new buildings or the building that has space for lift shaft. They also make a great calibration to a building where the lift will get extensive use, either due to the building size or where the lift will be the primary means of traveling between floors.
Passenger elevators are manufactured with advanced microcomputer lift controls to provide very high speed with effortless travel and perfect leveling. The passenger elevator has more advantages like they are suitable for low to medium rise buildings, a variety of capabilities elevators are available. Passenger elevators travel quickly between floors at 0.6 meters per second. They are extremely space efficient. These lifts are Machine-room-less (MRL) lifts and meet the aesthetic requirement of the building.
Hydraulic lifts : Hydraulic lifts use hydraulic fluid power to work. The lift moves up and down supported on the piston located at the base of the lift. These lifts cannot be used in buildings that are more than six storeys tall. Hydraulic lifts can be grouped into two types – lifts with holes at the base of the cavity and lifts without holes at the base of the cavity.
Traction lifts : Traction lift follows the principle of traction and weight balance. In this, the capsule meant to house passengers is counterbalanced in weight by another load of equal weight. Traction lifts are of two types namely geared and gearless. Lifts with gears consist of a gear box attached to the electric motor that powers the machine. The gears drive the wheel over which the rope with the cab on one end and counterbalancing weight on the other end are fixed. In gearless traction lifts, the electric motor is directly connected to the wheel.
Stairlifts : Stair lifts are special machines that are intended for domestic applications. They run up the staircase being attached to its structure. These single person machines are supplied and maintained by specialist stair lift manufacturers.
Scissor Lifts : These lifts get their name from the scissors that lift their working floor. They are different as they are mounted in pits and require no supporting mechanism above the platform. Hydraulic cylinders force the scissor arms together lifting the platform. They can handle very heavy loads and are widely used as car lifts. Small scissor lifts are the most widely used lifting equipment device in industry and commerce.
The revaluation of the higher floors of the property is directly proportional to the presence or absence of an elevator. The MRL lifts save building space, as it doesn't require space for a machine room and it also saves building electricity for up to 70%.
