FAQ
Elevator Guide Rails – Frequently Asked Questions
Are the speed limits for the different qualities precise?
No,
the calculations for comfort are carried out using a mathematical model
validated with practical tests, hence the speed limits set are
approximate.
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.
Why are the guide rails 5 meters long?
The
guide rails are 5 meters long because it is the appropriate
manufacturing length and allows the parameters for straightening to be
checked properly.
Do the guide rails have any surface treatment?
No,
the guide rails do not have surface treatments. On cold-drawn guide
rails the cold-drawn process modifies the mechanical features of the
material.
What difference is there between cold-drawn and planed guide rails?
The
process for cold-drawn involves stretching the material thus modifying
its structure. Planing involves machining the guide rail by stripping
the edgings.
How to name guide rails?
The
departure point of naming guide rails varies from country to country.
Some name the guide rail according to the width of its aspect of
guiding, such as T9, T16. While others name based on its weight, like
8LB, 12LB . However, we mostly name guide rail according to its width of
bottom, for example: T70, T50.
Do we offer samples?
If
your demand is just a few, then we can offer without charge, while if
the quantity is more, then we will charge considering your situation.
But, as for the postage, it’s on your side.
What’s the way of delivery and delivery date?
The
delivery date depends on the quantity of the goods. Usually, it takes
10 days to prepare one small container. And concerning the way of
delivery, we’d like to do 50% in advance by TT, then 50% after receiving
the copy of bill of lading by TT. If the policy in your country allows
only LC, then we hope you can provide us the name and SWIFT CODE of your
bank, in order to verify by ours.
