In architectural high-rise buildings, the selection of the right equipment with the most reliable quality, depending on the characteristics of the structure, type, and purpose of use brings solutions to both the producer company and the elevator company in the most appropriate economic conditions. At the same time, it ensures that the problems that may occur are detected and eliminated in advance. The facilities, the installation of which is completed with good and correct materials according to the well and standards, can offer a pleasant trip.
Today, there are new generation elevator technologies that can carry at high speeds for fast transportation in high structures. The system must be stabilized, that is, balanced, for transportation at high speeds to occur comfortably without shaking. The cabin is connected to the counterweight by hanging ropes wrapped on one or more spools to the upper parts of the well cavity. To ensure the dynamic equality of steel wires, many rope balancing techniques are being developed in our sector. One of them is a separate cable or chain equipment used to stabilize. The main task of this cable equipment is to ensure the dynamic alignment of the weight of the hanger steel wire.
The guide rails, which prevent skidding in the stabilization and safety of an elevator, are the carrier of the system. It is an important carrier and guidance system that is also used to take precautions against unwanted movements caused by take-off and stop accelerations during movement.
For the elevator to work stably, the door of the cabin should not pull the center of gravity towards the door. The center of gravity should be able to maintain its position. A system should be created in the cabin that maintains the location of the center of gravity, despite the greater load on one side. All possibilities should be considered, measured, and analyzed and calculations should be made for installation. Bending and tensile moments should be determined in the best way. They are important parameters in determining the rail cross-section in the most appropriate way to fix the rails to the system. The deterioration of the stability of the rails over time can lead to bending and bending risks and even breakage.
The characteristics of the suspension system created for the elevator rope to keep the system in balance are important calculations in the installation of rails. The calculations of both the suspension rope center for the rails and the installation of the rails for the suspension system are very important. Therefore, the durability of the rails and the quality of the supports used to secure the rails, that is, the consoles are very important at the installation stage when the installation is installed.
After Van Earthquake, when the damage caused by the elevators was examined, it was observed that the rails could not fulfill their duties due to the damage to the rail fasteners. Although the rails are of very high-quality, it has been determined that they are damaged because durable, high-quality, and suitable bearings are not used.
The material of the guide rails does not wear out. But the displacement of the bearings that provide their connection changes the position of the rails. Not every elevator project is the same. When projects are different, the same connection product should not be used in every project.
First, as EMA, we will continue to talk about the importance of consoles in rope balancing by mentioning the advantages of our quality rail fasteners.
Advantages of EMA Rail Consoles
Rail consoles should be of a quality that will not allow the rail to stretch and ensure that its stability is not disturbed. Particularly, bolted fasteners should be used. One side of the guide rails is fixed to the concrete in both directions with rail fasteners.
One side of the rail console is attached to the concrete. Concrete, which is a working material, changes during installation in newly constructed buildings or after a very short period. The number and distance of consoles should be placed with these changes in mind. In addition, it should be selected according to the characteristics of the installation to be installed in the well.
- As EMA wells with different characteristics, we have many console types to bring solutions. We produce fasteners that can be adjusted for each project, hold the rail tightly, and do not allow the rail to flex.
- We have rail connection systems that are fixed with bolts and clips.
- Our rail consoles are manufactured from certified metal sheets with side weight compartments and are galvanized coated. It is a bolted connection and is weldless.
- The biggest advantage of our products all parts are produced in sets. For example, in the project area if he needs a side-weighted elevator system it is a set with a fixed side-weight compartment between the rails and elevator rail consoles and an improved side-weight compartment that covers the entire need for nail bolts and dowels Dec.
- During the installation of the rails or when there is a change in the concrete, they are cut and replaced with a new one which does not need to be made suitable we produce consoles. We have developed designs that will adapt to each project. Our special nail designs are available. This, in turn, prevents processing to make the material suitable. Thus, the system is mounted with non-deformable fastener parts. Every support that has been processed creates a risk in the system.
- Used and worn bolts can be easily replaced. There is no need to replace the complete console with outdated small parts. The advantage of having a security code for each package in our products is that every part in the assembled part can be found.
- In the sets of EMA fasteners weight barcoded codes is available. With this feature, each package of our products has its security code. Our sets will maintain their safety for many years.
- On consoles manufactured by EMA there is no risk of breakage and cracking. We produce from a raw material that is resistant to breakage during seismic loads or earthquakes.
- EMA rail fasteners according to the weather and temperature conditions risks on the assembly day since the solution does not need to be introduced, it ensures that the installation is done on time without disrupting the work.
- Each project has a delivery date. With the advantage that our rail fasteners are in a set state, the safety of the system installed during the construction and assembly phase is not sustainable it ensures that projects are delivered on time. The easy packaging feature of our products for businesses saves both time and extra parts costs.
- Since it allows the rails to be mounted very firmly, there is less noise when the equipment performs its normal movement on the rails in buildings.
In our country, calculations are usually made on the absence of tremors in the vertical direction. But one of the important things for rails is it is to minimize the application of a force to shake the cabinet in the horizontal direction. It is to prevent the rails from opening sideways. In case of overloads or unwanted loads, the sideways movement of the rails poses a risk to the stability of the rail. This can also start to disrupt the balance of the system. It will prevent the rails from opening sideways the only equipment is consoles. That is why it is very important to check the stability of the guide rails during periodic inspections.
The task of the rails in balancing the ropes is many. It is also effective to prevent the ropes from being damaged if the cabin and counterweight are well and safely prevented from swinging. Its stability is ensured when mounting rails. It is assumed that there will be no bending or bending in the upright position of the rail, in which there is no deformation. The fact that the consoles, which have a very important task in maintaining the stability of the rails, cannot fulfill the task of a good rail holder creates inequalities in the rope tension.
Declaration load, cabin load, counterweight, balancing weight, the load of all equipment, and wind load affect the rails. If the stability of the rails starts to deteriorate, it also disrupts the performance of all equipment tasks. It causes the ropes, which are especially effective in load distribution, to disrupt their function and damage the material.
The rails, engine group, cabin, rope, and suspension are affected by the forces coming with the lift carrying capacity. Engine, cabin, rope, and other all equipment are assembled concerning the rails. Its technical characteristics are produced in high quality and capacity.
The functional properties of other equipment connected to steel wires are also being improved to equalize rope stresses. For example, double-speed motors are used in the drive within the limits of the acceleration of the movement, landing, take-off, and stop. Acceleration and deceleration can be controlled with electronic control. All techniques and devices developed are carried out to create balance after the elevator starts working. All of them are developed about the guide rails. It is assumed that the guide rails are rigid, and other equipment is installed.
As the elevator ropes are used as effective load distribution equipment to stabilize the system, they are subjected to bending fatigue and become elongated over time and begin to be damaged. Overloads can cause damage to the ropes while the elevator is moving. It makes for a bad trip. Usually, one of the biggest reasons for this is installation errors. After the installation of the rails, it should be evaluated how the fasteners hold the rails in case of balance disturbances in the system. Steel wires can sometimes start to be damaged depending on the equipment they are in contact with and work with. This situation also starts to affect the balance of the system.
The most undesirable situations in elevators are the rupture of the ropes, the disconnection of the drive group elements, and the fall of the cabin. The rails stop the cabin when the safety device is activated in such undesirable situations. Therefore, according to the characteristics of the well, its installation should be made with safe, high-quality, and correct materials. Calculations should be made that prevent the rails from becoming brittle. Bending and stress calculations must be performed completely and accurately. The rail fasteners must stiffen the rail by providing the best connection.
Today, in recent years, the elongation of the steel wires instead and not in contact with the air, comes with high protection against corrosion, with more load-carrying capacity, lubrication and maintenance-free, pulleys, non-abrasive, better energy-saving and more comfortable travel, offering called Belt, polyurethane-coated steel cables are introduced. Since the advantages of the belt are little known in our industry, steel wires are still widely used.
Let your rails perform their duty in the best way by connecting with consoles bearing the EMA signature.
