Classification of elevator rails

Elevator guide is divided into three categories: solid guide, heavy hollow guide

Solid guide rail is machined guide rail, which is made of guide rail profiles through mechanical machining guide surface and connecting parts. It is used to provide guide for car operation in elevator operation. Small specifications of solid guide rail are also used for reguide. Solid guide specifications are many, according to the weight per meter can be divided into: 8K, 13K, 18K, 24K, 30K, 50K, etc., according to the width of the guide plate can be divided into T45, T50, T70, T75, T78, T82, T89, T90, T114, T127, T140, etc.

With the improvement of people's requirements for elevator comfort and elevator speed, high-precision guide rail is the development direction of guide rail production. High-precision guide rail is to improve the accuracy of all aspects on the basis of ordinary guide rail. For example, the tolerance of guide surface size, the tolerance of guide rail height, and the tolerance of tenon and groove symmetry all change from 0.1mm to 0.05mm. And add a number of end shape and position tolerance requirements and improve the guide straightness, distortion requirements. High precision guide rail is used in high-speed elevator guide rail, not only the precision is higher than common rail, but also in the process to eliminate guide potential bending and twist deformation of factors, such as in front of the guide surface processing was carried out on the guide rail profile fully aging treatment, to reduce the residual stress in the rail profile, at the end of processing size and fine alignment before fully aging treatment again, Fully release the internal stress to reduce the rail bending caused by the stress after the rail installation.
