The elevator guide rail components mainly include guide rails, guide rail brackets, and pressure guide plates. The materials used for different components vary. The following is a detailed introduction:
1. Guide rail
Carbon steel：such as Q235 steel, has good toughness and welding performance, low cost, and is suitable for some ordinary elevators that do not have particularly high requirements for guide rail performance.
Excellent medium carbon steel: Similar to 45 # steel, after appropriate heat treatment, it can achieve high strength and hardness, and has good wear resistance and deformation resistance. It is a commonly used material for medium and low-speed elevator guide rails.
Alloy steel: For example, steel containing alloying elements such as chromium (Cr), manganese (Mn), silicon (Si), etc., can further improve the strength, toughness, and wear resistance of guide rails. It is suitable for high-speed elevators and heavy-duty elevators, and can better withstand various forces during elevator operation, ensuring the smoothness and safety of elevator operation.
2. Guide rail bracket
Channel steel: Q235 channel steel is commonly used, which has high bending strength and stability, and can reliably support guide rails. The shape and structure of the channel steel make it easy to install and fix, and can be flexibly adjusted according to the structure of the elevator shaft and the layout requirements of the guide rails.
Angle steel: Q345 angle steel is generally used, which has good compressive strength and torsional resistance. In the design of some elevator guide rail brackets, angle steel can be used in conjunction with channel steel or for areas that require high space and relatively low loads.
3. Pressure guide plate
High strength steel plate: such as Q345 steel plate, has high yield strength and tensile strength, which can effectively fix the guide rail on the guide rail bracket during elevator operation, withstand various forces on the guide rail, and prevent displacement or shaking of the guide rail.
Stainless steel plate: In some places with high requirements for elevator aesthetics and corrosion resistance, stainless steel plates such as 304 stainless steel are used to make pressure guide plates. It not only has good corrosion resistance, but also makes the appearance of elevator guide rail components cleaner and more beautiful.
In addition, some auxiliary components in elevator guide rail components, such as guide rail connecting plates, are usually made of steel similar to the guide rail to ensure the strength and stability of the connection; The outer shell of the guide rail lubrication device is generally made of plastic or aluminum alloy materials. Plastic materials have good corrosion resistance and insulation properties, while aluminum alloy materials have the characteristics of light weight and high strength.
