When buying and using an elevator, one of the points that should not be forgotten is the performance of the safety system of the elevator and its components. In addition to preventing personal injuries, this issue also prevents financial losses. For this reason, in the rest of this article, we want to address this important issue, so stay with Scud Lift.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

<\/span>What is the meaning of elevator safety system?<\/span><\/h2>

The elevator safety system, as its name suggests, provides elevator safety and safe and secure motion control for transporting passengers and preventing any danger and accident. Despite this system, if a problem occurs during the journey and transportation of passengers, the elevator cabin will stop.<\/p>

Every elevator is equipped with a main brake. When we go from one floor to another with the elevator, the main function of the elevator brake is to stop the cabin. For this reason, it is very important to have a correct and basic knowledge.<\/p>

The elevator brake, which is also known as the parachute, is installed on the yoke of the elevator cabin. Parachute makes us more confident when using the elevator of tall buildings and our health and other passengers are provided with its help.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

<\/span>Get to know the elevator safety system.<\/span><\/h2>

Each elevator consists of different components and must be equipped with a safety system. The safety system or parachute is actually an emergency brake that will be activated when the speed of the elevator exceeds and mechanically reduces the speed of the elevator.<\/p>

The interesting thing about this system is that it continues to operate even when there is a power cut and there is no disruption in its operation.<\/p>

In case of any malfunction, breaking and damage of the elevator tow wire or abnormal increase in the speed of the cabin downwards, the flow and operation of the parachute will be interrupted, and in this condition the cabin will stop. In addition, bumpers are used to increase the safety of the elevator.<\/p>

In a situation where the cabin or the balance weight of the elevator has exceeded the specified limit inside the elevator shaft and there is a possibility that it will hit the bottom of the shaft, the shock absorbers prevent accidents.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

<\/span>How does the elevator safety system work?<\/span><\/h2>

Parachute or emergency brake can have 3 modes, which are:<\/p>

  • Two movable brake shoes<\/li>
  • A fixed brake shoe and a roller<\/li>
  • A fixed brake shoe and two rollers<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

    The elevator shoe moves simultaneously until it is connected to one or more specified points. Braking force is generated by the friction between the surface of the brake shoes and the guide rail of the elevator. According to existing standards, the decelerating speed in gradual parachutes should be between 0.2 and 1, so that there is less shock to the passengers and the cabin. If the decelerator is greater than 1, the braking will happen very quickly and will cause a lot of shock to the cabin during braking.<\/p>

    If the acceleration decelerator is less than 0.2, very little force is applied to the elevator rail, and in this condition, the cabin must slide a greater distance on the guide rail, or there is a possibility that due to insufficient braking force, The floor of the elevator shaft will hit.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    The lowest part of the elevator is called the shaft or the elevator pit, which has many parts. For example, elevator cabin bumpers and balance weight bumpers are among the parts that are located in this part of the elevator. They are usually made of polyurethane and have two types of spring or hydraulic. If the elevator cabin is lowered too much, it will hit the bumpers and the pressure and speed of the elevator will be restrained to some extent. If the elevator is of hydraulic type, in addition to shock absorbers, jacks, flanges and hydraulic pipes are also present in the shaft.<\/p>

    <\/span>How are elevator bumpers installed?<\/span><\/h2>

    The following two methods can be used to install elevator bumpers:<\/p>

    • Under the cabin and frame, the weights should be fixed.<\/li>
    • To be installed on the impact platforms of the bottom of the elevator well.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

      In most cases, impact platforms are made of concrete, and if they are implemented in a standard and correct way, they will have a lot of resistance and stability. If concrete platforms cannot be used, portable impact platforms can be used. These portable platforms are made of iron beams, studs and plates.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

      <\/span>How does the elevator emergency rescue system work?<\/span><\/h2>

      One of the things that make people afraid of elevators is that when the cabin is moving, it gets electric and we get stuck in the elevator. In this situation, to move the mechanical brake cabin of the elevator, it is opened by a lever and the handwheel or flywheel of the elevator motor is turned.<\/p>

      Today, with the advancement of technology, there are better methods that detect power outages and then by inviting the passengers to relax, the elevator cabin is brought to the nearest floor so that people can get out of the cabin. In fact, in this situation, the elevator emergency rescue system takes control of the elevator motor and its mechanical brake, as well as the elevator door, by means of the elevator control panel and sends the necessary commands.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

      \n\t\t\t\t\t\t\t\t\t

      By feeding the elevator battery, the voltage of the elevator safety system circuit is supplied and after the necessary checks to close the elevator door, it sends the order to open the brake and the necessary power is produced to move the motor at a slow speed.<\/p>

      The cabin has moved to be aligned with the floor. Then, when the stop sensor is activated, the command to close the brake is sent and the elevator stops completely and the cabin door opens. In this way, people are prevented from getting stuck in the cabin in emergency situations.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
