A machine room was require to control most elevators in the past. Since they have an integrated safety mechanism, some elevators today don’t even require a machine room. Hydraulic, traction, machine-room-less, and vacuum are the four primary types of elevators.
Traction Elevators with and without gears
There are three types of geared and gearless traction elevators:
1. ELEVATOR WITH A TRACTION MOTOR
A wheel couple to an electric motor is position above the shaft of an Elevator Company, where ropes run across the wheel. It is the primary role of the ropes to raise and lower the Elevator Company car. If you’re looking for an Elevator Company that can go at a faster rate than hydraulic ones, then this is the best option for you.
With a counterweight, the weight of occupants and their cars is eliminate, making it easier for an elevator’s engine to move the elevator’s cargo.
AUTOMATICALLY OPERATED ELEVATOR
A gearbox is couple to the motor of the gear elevator. The wheel that moves the ropes is propell by the gears. Up to 500 feet per minute can be reach in this Elevator Company. It can go a maximum of 250 feet before running out of fuel.
ELEVATOR WITH NO NEED FOR A GEARBOX
Elevators that lack a gear do not have a way to regulate their speed. To put it another way, this explains why they can run at speeds of up to 2,000 feet per minute and travel as far as 2,000 feet. For skyscrapers, they are the finest choice.
2. A HYDRAULIC ELEVATOR
A piston locate at the bottom of the hydraulic elevator is typically use to sustain it. Elevator cars are push upward by an electric motor, while hydraulic fluid is pump down the piston by the electric motor. The hydraulic fluid from the piston is release by the valve when it’s time for the Elevator Company to descend. This elevator can only go 200 feet per minute and is typically seen in two to eight store structures. Hydraulic elevators are further broken down as follows:
HYDRAULIC ELEVATOR WITH ROPES
The elevator car’s motion is improve with the use of ropes and a piston in this design. It can go a maximum of around 60 feet on one charge.
ELEVATOR COMPANY USING A TYPICAL HYDRAULIC DESIGN
It has a sheave that extends beneath the floor of the Elevator Company pit, making it compatible with the design. A retraction piston is support in the pit as the Elevator Company begins to descend. When the elevator is lower, a collapsible telescoping piston may be require to fit into a shallower hole below the pit. Approximately 60 feet is the maximum distance that it can travel.
A HYDRAULIC ELEVATOR WITH NO HOLES
Unlike a traditional hydraulic elevator, which requires a hole or sheave install below the pit, the Hole-less Hydraulic Elevator does not. At the bottom of the pit, there are telescopic pistons. Using these pistons, the elevator car can rise to a height of 50 feet. Non-telescoping pistons, on the other hand, can only go up to 20 feet.
It is because hydraulic elevators are less expensive to install and maintain than other types of elevators that they have become so popular.
Because an electric motor operates against gravity, hydraulic elevators consume more energy. Checking the hydraulic fluid on a regular basis is essential because a minor leak might rapidly grow to a catastrophic occurrence or become an environmental threat.
3. MRL ELEVATOR COMPANY (MACHINE-ROOM-LESS)
The majority of elevators have a machine room place above the lift shaft. For maintenance, this Elevator Company has a machine install in the override space, and it can only be reach by climbing on top of the vehicle. A 250-foot-long, 500-foot-per-minute speed limit for this sort of elevator is in place.
For mid-rise structures, MRL (Machine Room Less) elevators are becoming increasingly popular since they are more energy efficient and take up less space during construction.
VACUUM (AIR-POWERED) ELEVATOR FOR THE HOUSE
Vacuum elevators were first introduce to the elevator industry in 2005 and do not utilize any cables or pulley systems. The natural principles of physics govern the operation of these Air-Driven elevators. This lift mechanism is essentially a tube in a vacuum seal with polycarbonate and aluminum components. The elevator’s ability to move depends on the presence of air both below and above the car.
It is necessary to drop air pressure in order to cause a lift in the tube when you press up. As you descend, the pressure below decreases, causing the Elevator Company to descend as well.
Because of the variety of models—from a single-passenger model to a wheelchair accessible three-passenger model—this type of Elevator Company is most commonly found in residential settings.
