Passenger lift - a kind of lifting equipment designed for vertical or inclined movement of people between floors. In some cases it is allowed to transport small-sized loads - if the total mass of people and luggage does not exceed the load capacity of the elevator.
No administrative or residential multi-storey building can do without the elevator equipment of this type. In residential buildings, cottages, hotels, hospitals, every minute flow of passengers obliges this technique to always be in perfect working order. This is especially important for shopping centers, as the profitability of retail space directly depends on the comfort of moving customers. And in many administrative and office centers, large private enterprises or shopping and entertainment complexes set up unique designer elevator cabins, which become an element of a single corporate image.
Advantages of passenger elevators
Considering that elevator equipment provides for transportation of people, strict requirements are imposed on it:
communication with the dispatcher;
Classification of passenger elevators
There are many different defining characteristics, according to which passenger elevators are classified. However, there is no single classification. Let's consider the main features:
On the level of comfort:
1. Business class - for office and administrative institutions, residential buildings of increased comfort. 2. Economy class - for multi-storey residential or public buildings. 3. Premium-class - for residences, private cottages, large companies.
By drive type
Electric elevators - installed in multi-storey buildings. A classic version of the hoist design: the models are equipped with traction ropes and a gearless motor, which drives the winch into motion. Such passenger elevators are characterized by high speed and are not limited in lift height.
Pneumatic lifts are driven by air pressure, which is pumped out of the cylinder below the cab. They are compact and easy to install, as they are not equipped with blocks, pistons and cables.
Hydraulic elevators - installed in low-rise buildings. This type of lifting equipment is "pushed out" by the hydraulic cylinder. The engine that drives the hydraulics is also electric, and the engine room can be removed from the mine by up to 20 m. The models have increased load capacity, and when the electricity is turned off, they gradually descend to the floor.
By the design of the drive
1. A winch of a drum type. The cabin is suspended on ropes rigidly fixed on the drum. When lifting, the ropes are wound on a drum. This type of drive is best used in low-rise buildings, otherwise larger drums and rope lengths will be required, which increases the price for such an elevator. 2. Winches with a traction sheave. To raise the cab, traction is generated by friction of the ropes against the working surface of the pulley. In this case, the winch allows you to suspend the counterweight and cab on several ropes, without complicating the design. The advantage of elevators with such a drive is an unlimited lift height.
By the location of the engine room
above the mine;
under the shaft or on the side of it;
Without engine room.
Doors of mine and cabin
Door drive type
manual (the passenger opens the door);
Semiautomatic (doors open manually, but closed with automatic door closer);
automatic (central and telescopic opening);
combined (cab doors - with automatic drive, and mine doors - with manual).
By the speed of the car
hydraulic drive type - from 0.3 m / s to 0.63 m / s
electric drive type - from 0.71 m / s to 4 m / s.
According to the management system
collective - registers all the commands, but executes them in accordance with the program of work (passing stops on calls can be made only when the car moves downwards, or when moving in both directions);
Single - for controlling one elevator;
group - to manage a group of elevators installed in one or more mines;
steam room - a kind of group management (used in residential buildings with high storeys).
Modern passenger elevators differ in their operational capabilities:
1. Lifting height with standard version - up to 33 floors (higher - when made to order); 2. Lifting capacity of a passenger elevator - from 220 kg to 3 tons; 3. The number of people being moved is from 4 to 30; 4. Speed - from 0.3 m / s to 18 m / s (in high-speed elevators); 5. Dimensions of the cabin - from 1 m² to 25 m² (width - 0,9-1,5 m, height - 2,2-2,3 m, depth - 1-2,7 m); 6. The width of the doors is from 0.7 m to 1.6 m.
Mine for passenger elevator
In accordance with the choice of type and size of the elevator, the type of mine is determined. The elevator shaft can be built into a finished building or erected in parallel with it. It is possible to attach the mine to the outer wall of the building. In the first case, redevelopment of the building will be required to allocate an area of at least 1.5 mx 1.5 m on each floor. The external shaft is installed on its own foundation, and the thickness of its walls is increased in order to heat the building. The elevator shaft itself can be "deaf" (concrete or brick); Adjacent to the supporting wall; Or self-supporting metalwork, lined with sandwich panels and other decorative materials.
