elevator guide rail

　　　The elevator guide rail is divided into three categories: solid rail, heavy hollow rail and escalator rails.
The solid guide rail is a machined rail by the rail profiles made ​​by machining the guide surface and the connecting portion, and its purpose is to provide a guide for the operation of the car in the elevator operation, the small size of the solid guide rail for redirection. Many solid rail specifications, weight per meter can be divided into: 8K, and 13K, 18K, 24K, 30K, can be divided into the rail bed width of T50, T70, T75, T78, T82 is, T89, T90, T114, T127, T140 and so on.
With the improvement of people improved comfort requirements of elevator and elevator speed, high-precision guide rail production development direction to improve all aspects of accuracy, precision guide is based on common rail, such as the size of the guide surface tolerance, rail height the tolerances, tongue and groove symmetrical tolerance from 0.1mm into 0.05mm, and increase the number of end geometric tolerance requirements and improve rail straightness distorted requirement. The precision guide is to use a guide rail in a high-speed elevator, not only with higher accuracy than the common rail, and also processes eliminate rail potential bending and distortion factors adequate aging treatment, for example, before machining of the guide surface on the rail profiles, sufficiently aging treatment in order to reduce residual stress within the rail profiles, in the size of the processing end portion before and fine Siaocian again fully release the internal stress, in order to reduce the stress caused by the rail after installation rail curved.
Heavily hollow rail is cold-formed rolled rail, multi-channel pass mold cold-formed molding by volumes plate after, mainly used for the elevator is running for re-provide guidance. Hollow rail per meter Weight to divided into TK3, TK5, the rail end shape can be divided into straight edge and cuffs, of that TK5 and TK5A.
Escalator rail is cold-formed rolled rails, is mainly used for escalators and moving sidewalks rung support and guide. Each escalator companies need to use a variety of cross-sectional shape of the escalator rail according to their own design, that use own escalators rail standards.
