An elevator car is of a construction which facilitates inspection and maintenance function while enhancing passenger safety. The car includes a closeable inspection and maintenance opening in a sidewall. A transparent inspection window or an inspection grille forms a closure for the opening. The closure may be lockable, and can also include a sensor to monitor its state.

Inspection opening in an elevator car

An elevator has a car that moves along at least one guiderail in a hoistway and the car is supported by at least one suspension rope that is driven by a drive unit. The drive unit has a drive motor that rotates rope sheave over which the suspension rope passes. The drive unit is located in an upper section of the hoistway and projects over at least part of the car. To assure safe access to the drive unit when the dimensions of the hoistway are efficiently minimized, the car has a closable opening in the roof through which the drive unit is accessible.
