Installation of elevators. Car lifts


Car lifts in mass use began to appear with the growth of cities up and with the need to save parking space. The ability to have your car next to or under a multi-story building in a metropolis is a huge convenience in life.

Basic requirements for car lifts

The organization of traffic flows in interchange hubs of megalopolises, at shopping centers and public buildings, involves the presence of multi-level parking lots, a common attribute of which is a car elevator.

Carrying capacity

She is the first requirement for such lifts. Cars are expensive and can be dangerous, so the safety margin of the elevator should ensure the safety of property and the safety of users. The capacity of a car elevator can not be less than 2 tons and, taking into account the representative class, up to 6 tons.

Cabin Width and Size

The standard size of the cabin is 3x6x2.3 meters, but at the request of the customer they can be made in other dimensions. The cabin may be without a door, but if the elevator is shaft-mounted, the shaft door is automatically moved apart upon arrival at the desired tier. Moreover, in most elevators, the cabin is made through the passage, so that the car entered on one side and left on the other. In this case, the machine does not reverse, which is much safer.

Reliability of car lifts

Elevators are powered by electric and hydraulic drives. Electric drives using AC or DC motors are used less often, since the height of car lifts is rarely higher than 4 floors.
The hydraulic drive works more smoothly, the stop accuracy is higher. For cars with small wheel diameters and low ground clearance, the stopping accuracy protects the car, and in the absence of sudden jolts, the elevator design works longer and more reliably.
In any case, for uninterrupted operation, it is desirable to reserve power.

Design Features

When equipping the cab with an open platform for the possibility of exit on the other hand, some designs can rotate around its axis. In such cabs, only cars without a driver move according to our legislation.

To ensure safety, multi-tier parking lots are equipped with traffic lights and sensors to avoid collision of cars. The most radical solution is the installation of two elevators to separate the flows, one serving incoming, the other leaving users.
Driving a car elevator should be clear and convenient. It happens:

  • internal, from the elevator car;
  • outdoor, key fob or card;
  • mixed, if there is a panel inside the cab and remote control.

Large parking lots are often staffed by a carrier that manages the elevator and monitors the condition of the equipment.
The modern car elevator is comfortable, safe, combines profitability and environmental friendliness. Their mines and equipment can be installed in new and old buildings without straining the structure, they are mounted simply and quickly. Installing a car elevator is a smart solution.

Freight Elevators - An Overview

gruzobyie liftyi

When planning the construction of a commercial or industrial premises in several floors, you should think about moving goods between floors. Efficiency of work, labor productivity, comfort and safety in them will depend on the speed of cargo lifting to the floor and descent to the desired level, ease of management and safe operation of freight elevators.

Features of freight elevators

GOST R 53771-2010 (ISO 4190-2: 2001) divides freight elevators into categories A and B in terms of usable area to maximum load capacity. The lifting capacity of elevators A reaches 5 tons, the lifting speed is up to 1 m / s. Category B elevators rise at speeds up to 2.5 m / s.

The purpose of the freight elevator is fundamental to determine its design and characteristics. On this basis, they are:

  • freight, accompanied by a lifter;
  • freight and passenger;
  • freight, not allowing escort.

The first two types are not much different from ordinary elevators, except for the lifting capacity and increased usable area. Purely freight elevators do not have a keypad inside the cab and there are no catchers. Such lifts do not need to be registered with Rostekhnadzor.
The drive of high-lift freight elevators for lifting to a small height is mainly hydraulic, and for high heights and low weight (up to several hundred kilograms) - electric.

At the location of the elevator relative to the building, they can be internal and external. Changing the purpose of the building often leads to the inability to install the elevator inside or this space is very expensive. In this case, the outdoor elevators are quite a reasonable solution. They can be installed anywhere on the perimeter of the structure, look stylish and modern, transport company employees and cargo.

Freight Elevator Structures

In addition to various combinations of transporting people and goods, the elevator designs of which contain the necessary human security systems, there are other lifts.

Scissor lifts

A hydraulic platform with a lifting capacity of up to 6 tons with scissor-type levers rises to a height of 8 m. Hydraulic cylinders provide upward movement. The platform descends smoothly under gravity, as the oil returns to the hydraulic system. Remote control wireless or remote control at the installation site of the elevator. The platform perimeter is equipped with sensors that monitor any distortions and obstacles to movement and block movement.

Mast lifts

They are racks along which the platform moves at an angle or vertically to a height of 16 meters. Installation of the lift is possible inside and outside the building. This design is used in many small freight elevators with a lifting capacity of 50 kg or more. They are cheap due to ease of installation and lack of a mine.

Mine elevators

The platform moves inside the metal frame, the engine room in modern elevators can be absent or located either above or below. Most valuable, in this design there is no limit on the height of the load.
The user who has decided to purchase a freight elevator needs to clearly know the tasks for him and have the necessary budget. Specialists will select from a huge variety that they will mount and coordinate what is needed in the manner specified by law.

Lifts for the elderly and disabled

The Accessible Environment program, which has been operating in the Russian Federation since 2009, provides for the creation of comfortable conditions for the disabled and the elderly. The presence of special lifts or elevators in the places of their compact residence, as well as in any modern public building, is an indicator of this program.

Features of elevator movement control

Due to various possible restrictions on the health of older people and people with disabilities, specific requirements are imposed on the elevator control system:

  • Pressing the control buttons is duplicated by sound messages and light indication.
  • The buttons themselves are made more convex with embossed symbols, larger and highlighted. The distance between them is greater than usual.
  • The control panel in the cockpit and the call buttons are located at the level of the armrests of the strollers for the convenience of the disabled.

Such solutions allow low-mobility citizens to independently manage the elevator without accompanying persons.

Elevator cabins for the disabled and the elderly

Cab design requirements are defined in GOST R 51631-2008 and GOST 53770-2010:

  • The overall dimensions of the cabin and doorway are calculated based on the dimensions of the strollers specified in GOST 30471-96.
  • Lack of automatic closing of the door (or the possibility of adjusting the delay).
  • To facilitate wheelchair maneuvers in the cab, handrails and mirrors are required.
  • Comfortable lighting and contrasting colors finish for people with low vision.
  • The flooring in cabs must not slip, so as not to endanger people with a cane or walker.

Installation and modernization of lifts in residential areas

Decree of the Government of the Russian Federation No. 1521 dated 12/26/2014 made the SNiP 54.13330.2011 clauses ensuring the arrangement of buildings when living with handicapped groups mandatory during construction.

In low-rise buildings, the installation of elevators or elevators in homes for people with disabilities and elderly people most often consists of open or closed vertical and inclined compact elevators or folding staircases inside or outside buildings. For buildings below 9 floors, one lift is sufficient.

High-rise multi-storey buildings are equipped either with standard passenger elevators, modernized taking into account the requirements of GOST and SNiP for use by people with limited mobility and elderly people, or already taking into account these requirements from the range of products manufactured by most manufacturers.

The use of international events on the territory of the Russian Federation to create an accessible environment is undoubted. Acceptance of public buildings and structures for them is carried out by international organizations and their requirements are strictly observed. The most indicative in this regard is the set of rules of the joint venture 59.13330.2012, adopted and implemented in preparation for the Sochi Olympics. Gradually, the situation for the better is changing in the outback, which pleases.

Hospital Lifts

hospital lifts

It is certainly sad to be in the cabin of a disconnected elevator, but the malfunction of a hospital elevator is much worse, when the patient’s life may depend on it. Supervision of elevators in hospitals is even more stringent, and the requirements for them and their equipment are different from conventional lifts.

The specifics of hospital elevators

Special requirements for hospital elevators are formulated in GOST 22011-95. One of the main conditions that determine the safety of such lifts is that the cabin must reach the nearest floor and the doors will open open even when the power supply is cut off. This should be achieved either by redundant power supply, or mechanically, but necessary.

Other distinctive features of such elevators are the following:

  • When people are in the booth, other calls are ignored.
  • The complexity of modern equipment to accompany the patient requires the installation of outlets for uninterrupted power in the cabin and adjustable lighting.
  • The speed of the cab is not more than 1.6 m / s, and the noise should not exceed 60 dB, which requires a drive without a noisy gearbox.
  • The deviation of the stop of the cab floor from the platform on the floor must not exceed 15 mm.

There are a number of requirements for the hospital elevator car itself:

  • Walls must be stainless steel for easy sanitation.
  • The flooring must not slip.
  • Its overall dimensions and carrying capacity make it possible to transport any options for wheelchairs or beds of a particular hospital and accompanying medical staff.
  • The dimensions and design of the doors are defined by the standard, but in the case of individual projects, opening on two or even three sides may be provided.
  • The temperature in the cabin cannot be more than +55 degrees, and the humidity should be less than 98%, which often requires forced ventilation.

In addition to various design features, the medical staff responsible for transporting patients is trained in the use of the elevator, and sometimes it is provided for in the staff of the elevator who is responsible for this. The lifter must prevent the elevator from stopping and call the electrician responsible for the equipment as quickly as possible. The condition of the elevator mechanisms is regularly monitored to prevent emergency situations.

Elevator manufacturers, both domestic and foreign, have in their nomenclature an extensive list of models of elevators for hospitals. High reliability, safety and various equipment make it possible to equip them not only with hospitals, but also with children's health facilities, homes for the disabled and the elderly.

Elevator manufacturing in China

Skyscrapers Shanghai China

In recent years, China has become the main economy of the world, the population of China is also huge, and there are few densely populated territories. Definitely need to be built up, and in large quantities. What about the elevators?

World dinosaurs of the industry, placing their production in China

At the dawn of the Chinese perestroika, they managed to catch the leaders of world industry in the opportunity to receive super-profits from the location of production in China. Skillfully creating the illusion that China has become, as it were, a modern colony of transnational corporations, the Chinese have received investments not so much monetary as technological and innovative.

The oldest global elevator brands have their full-cycle production in China:

  • Otis,
  • Kone,
  • ThyssenKrupp Elevator.

For example, the factory of the German company ThyssenKrupp AG in Guangdong province is equipped with one of the largest test elevator towers with a height of 248 meters. This plant will produce lifts of the future, without cables (MULTI), on magnetic cushions with moving cabs both vertically and horizontally already in 2020.

Strict control, state-of-the-art equipment, technologies and unique developments of the leading developers in the world made it possible to create in China for 30 years its own school of elevator designers and designers. The production culture and high-quality local equipment have grown so much that it made it possible to create an industry from scratch.

Chinese elevator manufacturers

The Chinese ability to quickly learn and dramatically scale successful solutions (the advantage of central planning) brought their elevator builder companies to the elevator market:

  • KOYO Elevator Co,
  • TAISHAN (Shanghai Guotai Elevator Co Ltd.),
  • UG Elevator,
  • SJEC Corporation.

A wide range of equipment for elevators based on German technology and famous for security systems is manufactured under the Kouo brand. CANNY, in addition to elevators, manufactures escalators, travelators and accessories for them. SJEC Corporation is also known for its advanced developments in cab design.
All these companies have a full production cycle for elevators, large production capacities for the production of a variety of types of elevators. They have seriously supplanted traditional Japanese and Korean manufacturers in the Asian markets and are actively entering the world.

Elevator Recommendations

The choice of the Chinese elevator economy from the point of view of the consumer in the Russian Federation comes down to finding a solid Russian company - a dealer of well-known Chinese brands. This will remove the issues of service, spare parts, and the reliability, quality and comfort in them fully corresponds to modern world requirements at a significantly low price. Successes.
