Abstract
The invention relates to a construction time elevator arrangement comprising a hoistway; a protection deck mounted within the hoistway for protecting the portion of the hoistway below it from falling objects; the protection deck comprising a roof member extending diagonally across the hoistway and covering the hoistway such that it blocks objects and/or water from falling into the hoistway below it; and a cross member extending in horizontal direction across the hoistway below the roof member. The cross member is pivotally connected with the roof member, the protection deck being collapsible into a transport state by pivoting the cross member and the roof member towards each other. The invention relates to a method implementing the construction time elevator arrangement.
