Perpendicularity is meant the perpendicular from top surface and bottom milling surface of guide rail, ISO standard specification is ≤0.1mm. The perpendicularity will impact the guide rail joint accuracy and brings implication to the elevator smoothness and comfort.
It means the centering of tongue and groove, ISO standard specification is ≤0.1mm, high precision elevator guide rail is between ≤0.05mm and ≤0.03mm. Centering brings significant impact to the guide rail
joint precision, 2 guide rails failed in the centering specification when joint together will reducing the movement smoothness of guide shoe, it further will influence to the stability movement and comfort of elevator.
Increase carbon content in steel, the breaking point and tensile strength will be increased as well but the elongation and resistance to impact will be reduced.
Silicon acts as a reducing and deoxidizing agent, Manganese acts as deoxidizing and desulfurizing agent, both improve toughness and strength property of steel. Phosphorus and Sulphurn are toxic agents in the steel, both reduce elongation and toughness property of steel, theirs content is less than 0.045%. The hardness of guide rail will ensure the safety grip gains sufficient friction during the break mechanism.
Naming of Guide Rail
Naming of guide rail follows ISO standard, machined guide rail consists of 3 elements e.g. T type guide rail, width of the base and manufacturing process. /A means cold drawn guide rail, /B means machined guide rail, /BE means high precision machined guide rail, if there is necessity using the numbering to show the width of the base and cutting plane of the guide rail e.g. T45/A, T50/A, T70-1/B, T75/B, T78/B,
T82/B, T89/B, T90/B, T114/B, T127/B, T127-1/B, T140-1/B, T140-2/B, T140-3/B.
As for material, labor, transportation cost and exchange rate are changing, the price for this guide rail is just for reference only, please contact us beforehand if you are interested.
