As the elevator's guidance system, the elevator guide rails are an important component affecting the safety and stability of elevator.it is one part of the inner workings of most elevator and lift shafts, functioning as the vertical and internal tracking rail.The guide rails are fixed to two sides of the lift shaft; one guide is for the elevator car and the other for the counterweight. In tandem, these rails operate both as stabilization within the shaft during routine use and as a safety system in case of emergency stops.
Frequently Asked Questions - Elevator Guide Rails
What difference is there between cold-drawn and machined guide rails?
The process for cold-drawn involves stretching the material thus modifying its structure.Machined guide rail is by stripping the edgings.
Why can not the cold-drawn guide rails be used at speeds over 1.6 m/sec?
Because the cold-drawn process produces short bends caused by the variations in the raw material thickness rolled along the section.These bends make the lateral acceleration rates high.
Do the guide rails wear out?
No, guide rails under normal working conditions do not wear out because both the guide shoes and the rollers are softer than the guide rails.The guide rail may only be damaged through the action of the safety gear.
Why are guide rails made of steel?
Guide rails carry out functions of both guiding and safety,since they are the structural member on which the safety gear works.Steel is currently the cheapest material that perfectly meets these two requirements.
This production line takes full hydraulic driven, it is reliable, high accuracy and high efficiency, etc.
The overall production line is the production equipment combined with technologies such as leveler/punching, roll forming, cutting, etc.
The production line is composed of de-coiler system, punching system, roll forming system, cutting system, electric control system, etc.
