Elevator workers in our country celebrate their professional holiday on February 1. More than seventy years ago this day was the beginning of domestic elevator construction.
Elevators can be not only cargo and passenger, but also special - designed for transportation of physically challenged passengers and disabled people.
A series of interstate standards, in the development of which Standardinform took part, will come into force for the first time in June 2021 for such products.
GOST 34682.1-2020, Lifting platforms for persons with impaired mobility. Safety requirements for the construction and installation. Part 1. Stairlifts and inclined lifting platforms.
The load-carrying device covered by this document allows one person with or without a wheelchair to move between specified levels.
It is an electrically powered platform that moves over stairs or an inclined surface in a straight or complex trajectory.
The movement speed of this elevator is 0.15 meters per second.
The rated load per person is at least 115 kg, per person with a wheelchair at least 250 kg.
Tilt platforms carrying a person in a wheelchair must be equipped with a device that eliminates the possibility of starting in case of overloading.
The platform shall not start if the rated carrying capacity is exceeded by 25% or more.
GOST 34682.2-2020, Lifting platforms for disabled persons and other persons with impaired mobility. Safety requirements for the construction and installation. Part 3. Rules and methods of examinations (tests) and measurements by certification. Rules of sampling.
The standard applies to lifting devices that move vertically along the shaft.
The document details safety requirements for the design and installation of these products.
The minimum lifting capacity of the device for one user in a power wheelchair and an attendant is 385 kg, the minimum dimensions are 1100 by 1400 mm.
Mechanical and electrical elements of the equipment must be reliably protected from harmful environmental influences that can occur at the site of installation such as moisture, temperature, corrosion, ingress of solid bodies.
GOST 34682.3-2020, Lifting platforms for disabled persons and other persons with impaired mobility. Safety requirements for the construction and installation. Part 3. Rules and methods of examinations (tests) and measurements by certification. Rules of sampling.
Specialists of testing laboratories carry out tests and measurements.
The selected sample must have at least two stops with access to the landing sites.
The standard defines the permissible error of tests and measurements. It is: when measuring current voltage, temperature, mass, acceleration and humidity ±5%; when measuring time ±0.2% and ±10% when measuring illumination.
Recording equipment must be able to detect signals that change in time, within a range of not more than 0.01 s.
