Important guidelines and the role that elevator shaft guide rail installation plays. Elevators are essential vertical transit devices in contemporary buildings, especially for high-rise structures, and their stability and safety are crucial. Especially the world’s top-ranked excellent brand elevator companies:
● ThyssenKrupp(Germany)
● Kone(Finland)
● Schindler(Switzerland)
● Mitsubishi Electric Europe N.V. (Belgium)
● Mitsubishi Heavy Industries, Ltd.(Japan)
● TK Elevator AG(Duisburg)
● Doppelmayr Group(Austria)
● Vestas(Danish)
● Fujitec Co., Ltd.(Japan)
They all attach great importance to the safety performance of elevators.
The installation quality of elevator shaft rails is directly related to the operating efficiency and safety of elevators. Therefore, understanding the installation standards of elevator shaft rails will not only help professional construction personnel improve the installation quality, but also allow the public to better understand the core elements of elevator safety.
Track material selection: the key in the foundation
High-strength steel that has been hot- or cold-rolled is typically used to make elevator hoistway rails. These materials need to have outstanding strength, wear resistance, and deformation resistance and adhere to industry or national standards. The track’s job as the elevator car’s “support” is to make sure that during long-term operation, there are no wear, deformations, or other problems. As a result, it’s important to make sure the materials’ quality satisfies all applicable technical standards while choosing track materials. Any usage of subpar materials could put the elevator’s operation at risk for safety issues.
The guide rail is accurately positioned and firmly fixed
The elevator hoistway’s center line and the installation position of the guide rails must be perfectly aligned. During installation, pay close attention to the horizontal and vertical alignment. The elevator’s ability to operate smoothly will be impacted by any small mistake. For instance, there are typically 1.5 to 2 meters separating the guide rail bracket from the hoistway wall. To keep the guide rail from moving or vibrating while the elevator is operating, every bracket must be sturdy and solid when employing expansion bolts or galvanized embedded base plate for fastening.
Verticality of guide rails: “balancer” of elevator operation
The verticality of elevator guide rails directly affects the smoothness of elevator operation. The standard stipulates that the verticality deviation of the guide rails should be controlled within 1 mm per meter, and the total height should not exceed 0.5 mm/m of the elevator lifting height. In order to ensure verticality, laser calibrators or theodolites are usually used for precise detection during installation. Any vertical deviation beyond the allowable range will cause the elevator car to shake during operation, seriously affecting the passengers’ riding experience.
Guide rail joints and connections: details determine safety
Guide rail installation requires not only accurate verticality and horizontality, but also joint processing is equally important. Special guide rail fishplate should be used for joints between guide rails to ensure that the joints are flat and without misalignment. Improper joint processing may cause noise or vibration during elevator operation, and even cause more serious safety problems. The standard stipulates that the gap between guide rail joints should be controlled between 0.1 and 0.5 mm to adapt to the changes in material thermal expansion and contraction to ensure that the elevator always runs safely.
Guide rail lubrication and protection: increase lifespan and decrease maintenance
By lubricating the guide rails as needed to reduce friction between them and the sliding parts of the car, you can extend their service life when the elevator is in use. Furthermore, precautions should be taken during construction to keep exposed guide rail portions free from dirt, stains, and other damage. The right lubrication and protection can guarantee the elevator runs well and reduce the frequency and cost of later repairs.
Acceptance test: the last checkpoint to ensure the safety of elevator operation
To ensure that the elevator's overall performance meets national regulations, a series of comprehensive acceptance tests must be carried out after the installation of guide rails. Load tests, speed tests, and safety performance evaluations are among these tests. These tests ensure the stability and safety of the elevator during actual operation by quickly identifying and resolving possible problems.
In addition to increasing the elevator's operational effectiveness, a skilled installation crew and stringent implementation guidelines can make riding in the lift safer and more comfortable for users. Thus, it is the duty of construction workers as well as a shared concern of building developers and users to pay attention to elevator guide rail installation standards.
