Important notes on Electronic Submissions

In order to submit your technical dossier electronically, all the documents that form part of the package must be readily viewable in Adobe Acrobat Reader (.pdf).  


A variance from regulations and adopted safety standards may be reviewed for consideration, but it is not guaranteed to be granted,

Variances allow designers flexibility to use designs that do not strictly comply with current regulations but include other methods to ensure equivalent elevating device safety.

Service fees to evaluate variances are charged at an hourly rate.
