Historically, man has been afraid of heights, flying, or being suspended in the air, and therefore the elevators. Who more or less, all have feared ever in our life that the elevator fell down the shaft, or have thought about what would happen if there was a power outage or mechanical failure, and we stay locked in the cabin ...
Claustrophobia and terror to mechanical failure have been a collective fear that has become very popular since the very moment when these devices were invented, back in the nineteenth century. Even the film industry has taken advantage of this collective fear in his films as a recurring scenario has even devoted entirely versed on "lifts murderers" they come alive and kill people movies.
But do you really can fall elevators? Not really. It finds the Professor of Applied Physics, Antonio Ruiz de Elvira , who argues that if the building model is well designed, the elevator, as simple as it may sound, has an extremely simple mechanism that was invented in 1852 and based on a Flexible crossbow and thanks to an elementary physical process, when possible malfunction steel cables that pull this spring is cut, the fall of the car would slow down.
Figures: Spain, a country elevators
Spain stands as one of the world's countries with more lifts per inhabitant, in particular lifts are 19,8 per 1,000 inhabitants a ratio well above other countries with high population density such as the UK, France and emerging countries as China.
By way of example, one study suggests that if to agree all the lifts of Spain, they could move the entire population of the nation five times per day.
The fact that Spain is erected as a world power in the field of elevators increases singularly fears that we referred to earlier in this post: the electro-mechanical failure that causes being trapped in the cabin and of course the falling into the void.
Experts point as their own accidents occur in an elevator:
1. That the passenger fall to empty the tunnel when opening the elevator door is not parked the car. The solution is as simple as putting a lock.
2. That the passenger (especially children) are trapped between the gateway and the car at the time of access. This is almost impossible to happen because the new installation guidelines and study regulations regulate distances between the cab and the gateway
3. - That the lift cables traction slip on the pulley being worn throats of it. It circumvents this risk with proper maintenance program.
4. - That a blow to the upper or lower ends by failure safety limits, which is overcome by a bumper in regulatory conditions occur.
5. - That a bad rescue maneuver in which the passenger wanting to get caught out or fall vacuum is made. TV assistance to be discussed in this post ensures protocol "salvage" in this case can not occur.
6. That the parachute does not act in the eventual fall of the car, when cut cables or pull them slipping and the elevator falls at a rate 20% higher than the nominal.
7. What electrocution or shock occur in the engine room, not having the engine room conditions and / or objects that should not be there.
What are the safety of the elevators to ensure their safety?
The security features that usually has all elevator or escalator to ensure their safety, are as follows:
Front doors locks: those that give each staircase and serve to prevent improper opening of doors when the car is not present on the landing and avoid "breaks vacuum".
Parachutes and speed limiter: for the lift cushion a possible fall or not reach speeds higher than regulatory.
Car door locks with sensors: These sensors prevent entrapments arms and hands and condition the opening of the central door to the landing.
Ground connection electrical installation: for an eventual failure in installing the elevator does not paralyze the operation.
Cockpit indicators: they indicate at all times the state of operation of the lift, if it is running, stopped in breakdown ...
Indicators in the engine room: indicate normal and abnormal functioning of both the elevator and the same engine room.
Safety limits at the ends: also called "bumpers" security. They are dampers prevent the elevator rises faster than the regulation or down at a speed also higher, and the bumper cushion any falls cabin.
Emergency alarm: Notifies the failure of the apparatus both passengers and staff in the building and remote assistance service.
The elevators rise to the European security
As if that were not enough, the European Union dispels all fear us regarding the safety of lifts throwing a directive on these means of transport.
A directive is a mandatory standard for member countries, and the new "Directive 2014/33 / EU harmonization of legislation of Member States relating to lifts and safety components of lifts" take effect in Spain from of April 20, 2016 and we will force to redouble security conditions in the new elevators, with measures such as: have a service remote assistance, provide blocking automatic doors or improve leveling of the elevators.
Presumably all, as has happened with previous directives, to transpose it into national law also applies to the old elevators by Royal Decree.
Recall that are estimated at 500,000 "old" elevators in Spain. This is to be overcome deficiencies by that start complaints in the old, such as the noise produced by the engines, the abruptness in starts and stops, the wear suffered pulleys, mislevelment at stop cabins with floor and wear and tear of the other building elements, among others.
New Directive on security
The new directive is at the gates of entry into force has many advantages in terms of safety is concerned:
- On the one hand Europe unifies and regulates the manufacture, design, assembly and distribution of the elevators.
- On the other hand, it emphasizes the concept of "market surveillance", in the sense that orders the surveillance of the safety of lifts so that is controlled from its origin (design, manufacturing) to its commissioning. To do this, it orders the traceability of the safety of the elevators are monitored. So, before any eventual detection of failure of a product model or design, can be located in the European Union all lifts afflicted with this anomaly.
And finally, orders the available instruments to ensure their safety during their lifetime and operation through maintenance of three types: preventive, corrective and predictive. Corrective maintenance is performed when it has found a fault or anomaly and maintenance service moves to resolve it. Preventive maintenance is that aimed to provide the installation of the necessary elements to prevent deterioration of the same for its continued use over time (eg oiling), and finally, predictive maintenance is one that detects futuribles failures system that could cause a permanent failure. In short, all control is little.
