SG15 sliding guide shoe

Dimension drawing

Technical parameters

The SG15 sliding guide shoe is usually composed of the following main parts:

The main body of the guide shoe is usually made of high-strength wear-resistant materials, such as polyurethane or nylon, etc., which have good wear resistance and impact resistance.

Guide plate: The part that comes into direct contact with the elevator guide rail, usually made of metal materials, and its surface has undergone special treatment to enhance wear resistance and reduce the coefficient of friction.

Spring system: It is used to adjust the contact pressure between the guide shoe and the guide rail, ensuring that the guide shoe can maintain good guiding performance under different load conditions.

Fixing device: It is used to secure the guide shoe to the elevator car or counterweight, and usually includes fasteners such as bolts and nuts.

The working principle of the sliding guide shoe is to guide the elevator car or counterweight through the sliding friction between the main body of the guide shoe and the elevator guide rail. During the operation of an elevator, the frictional force between the guide shoes and the guide rails varies with the load and speed. Therefore, the design of the guide shoes needs to take these factors into account to ensure that they maintain good guiding performance under various working conditions.

Material selection

The material selection of the SG15 sliding guide shoe has a significant impact on its performance and service life. Common materials include:

Polyurethane: It features excellent wear resistance, impact resistance and oil resistance, and is suitable for high-load and high-speed elevator systems.

Nylon: It has excellent wear resistance and self-lubricating properties, and is suitable for elevator systems with medium loads and speeds.

Metals: such as stainless steel or aluminum alloy, are typically used for guide plates or fixtures, featuring high strength and corrosion resistance.

The selection of materials needs to be determined based on the specific working conditions and usage environment of the elevator to ensure that the guide shoes can maintain good performance under various conditions.

Manufacturing process

The manufacturing process of the SG15 sliding guide shoe also has a significant impact on its quality and performance. Common manufacturing processes include:

Injection molding: It is suitable for plastic materials such as polyurethane and nylon, and can produce guide shoe bodies with complex shapes and precise dimensions.

Mechanical processing: Applicable to metal materials, it can produce high-precision guide plates and fixtures.

Surface treatment, such as electroplating and spraying, can enhance the wear resistance and corrosion resistance of the guide shoe.

The selection of manufacturing processes needs to be determined based on materials and production requirements to ensure the quality and performance of the guide boots.

Installation and Maintenance

The installation and maintenance of the SG15 sliding guide shoe also have a significant impact on its performance and service life. The following points should be noted during installation:

Installation position: The guide shoes need to be installed at the correct position in the elevator car or counterweight to ensure good contact with the guide rails.

Fixing method: The guide shoes need to be firmly fixed to the elevator car or counterweight through fasteners such as bolts and nuts to prevent loosening or falling off during operation.

Adjust the spring system: The spring system of the guide shoe needs to be appropriately adjusted according to the load and speed to ensure that it maintains good guiding performance under various working conditions.

The following points should be noted during maintenance:

Regular inspection: Regularly check the wear and tear of the guide shoes and replace those that are severely worn in a timely manner.

Cleaning and lubrication: Regularly clean the guide shoes and guide rails and lubricate them appropriately to reduce the coefficient of friction and wear.

Fastening inspection: Regularly inspect the fixing device of the guide shoe to ensure it is firm and reliable.

Application field

SG15 sliding guide shoes are widely used in various types of elevator systems, including:

Passenger elevators: Passenger elevators used in high-rise buildings, shopping malls, hotels and other places need to have good guiding performance and safety performance.

Freight elevators: Freight elevators used in factories, warehouses and other places need to have high load capacity and wear resistance.

Medical elevators: Medical elevators used in hospitals, clinics and other places need to have high safety and reliability.
