Elevator guides can be divided into three main categories: solid guide, counterweight hollow rail and escalator guide.

实心导轨是机加工导轨，是由导轨型材经机械加工导向面及连接部位而成，其用途是在电梯运行中为轿厢的运行提供导向，小规格的实心导轨也用于对重导向。实心导轨规格很多，按每米重量可分为：8K、13K、18K、24K、30K、50K等，按导轨底板宽度可分为T45、T50、T70、T75、T78、T82、T89、T90、T114、T127、T140等。

The solid guide rail is a machining guide, which is made of the guide and connecting parts of the guide rail. Its purpose is to guide the operation of the car in the operation of the elevator, and the small size of the solid guide is also used for the heavy guide. 8K, 13K, 18K, 24K, 30K, 50K, etc. can be divided into T45, T50, T70, T75, T78, T82, T82, shrinking, shrinking, etc, according to the width of the guide rail.

随着人们对电梯舒适度要求的提高及电梯速度的提高，高精度导轨是导轨生产的发展方向，高精度导轨是在普通导轨的基础上提高各方面的精度，比如导向面尺寸公差、导轨高度公差、榫槽对称度公差都由原来的0.1mm变为0.05mm，并增加了多项端部形位公差要求并提高了导轨直线度、扭曲度要求。高精度导轨是使用在高速电梯上的导轨，不但精度要高于普通导轨，而且还在工艺上消除导轨潜在的弯曲及扭曲变形因素，比如在导向面加工前对导轨型材进行充分的时效处理，以降低导轨型材内的残余应力，在加工端部尺寸前及精校前再次进行充分的时效处理，充分释放内应力，以降低在导轨安装之后应力引起的导轨弯形。

With the improvement of elevator comfort requirements and elevator speed, high precision guide rail is the development direction of guide rail production. High precision guide rail is based on the ordinary guide rail to improve all aspects of precision, such as the dimension tolerance of the guide surface, the height tolerance of the guide rail, and the tolerance of the tenon and groove symmetry from the original 0.1mm to the 0.05mm, It also adds a number of terminal tolerance requirements, and improves the straightness and twist requirement of the guide rail. High precision guide rail is used on high speed elevators, not only to be more accurate than ordinary guideways, but also to eliminate the potential bending and distorting factors of the guide rail, such as the sufficient aging treatment to guide the guide profile before machining in order to reduce the residual stress in the guide profile and the dimension of the machining end. The full stress relief is applied before and before finishing, to fully release the internal stress, so as to reduce the guideway induced by stress after rail installation.

对重空心导轨是冷弯轧制导轨，是由卷板材经过多道孔型模具冷弯成型，主要用于电梯运行中为对重提供导向。空心导轨按每米重量可分为TK3、TK5，按导轨端面形状可分为直边和翻边，即TK5和TK5A。

The heavy hollow guide rail is a cold-formed rolling guideway, which is made of rolled plate through multi pass die cold bending. It is mainly used for guiding the counterweight in the elevator operation. The hollow guide rail can be divided into TK3 and TK5 according to the weight of each meter. According to the shape of the end face of the guide rail, it can be divided into straight sides and flanges, namely TK5 and TK5A.

扶梯导轨是冷弯轧制导轨，主要用于自动扶梯和自动人行道的梯级的支承和导向。每个自动扶梯企业都根据自己的设计需要使用各种截面形状的扶梯导轨，即都使用自己的扶梯导轨标准。

The escalator guide rail is a cold-formed rolling guideway, which is mainly used for supporting and guiding escalators and automatic sidewalks. Every escalator enterprise uses all kinds of cross section escalator guides according to their design needs, that is, they use their escalator guides.
