Lifts and service lifts - Part 11: Code of practice for the undertaking of modifications to existing electric lifts

Recommendations for the modernization, or modification, and improvement of electric passenger and goods passenger lifts.

This British Standard, a part of the BS 5655 series, gives recommendations for the modernization, or modification, and improvement of electric passenger and goods passenger lifts, with traction drive or positive drive, serving defined landing levels, having a car designed for the transportation of persons or persons and goods, suspended by ropes or chains and moving between guide rails inclined not more than 15° to the vertical.

The most important reason for modifications is to enable owners to fulfil their duty to provide for the safe operation of their lift installation(s). Additional reasons for modification can be to: change the use of a lift, which might result from a change in use of the building; improve reliability; update technologically; improve traffic handling; improve ride quality; reduce energy consumption; improve the aesthetics. These types of modification are often termed “modernization”.

In some situations (e.g. potentially explosive atmosphere, extreme climate conditions, vandalism, transporting dangerous goods, etc.), additional measures might need to be taken to those recommended in this standard.

This British Standard supersedes BS 5655-11:1989, which is withdrawn.

This standard includes the following cross references:

BS 7255:2001, BS EN 81-1:1998, BS EN 81-80:2003, BS EN 12015, BS EN 12016.
