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 degree to the vertical.

This part of BS 5655 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 byropes or chains and moving between guide rails inclined not more than 15° to the vertical.

This part of BS 5655 does not cover any of the following types of lift:

1. new lifts (see Note 2);
2. lifting appliances, such as paternosters, mine lifts, theatrical lifts, appliances with automatic caging, skips, lifts and hoists for building and publicworks sites, ship\'s hoists, platforms for exploration or drilling at sea, construction and maintenance appliances:
3. installations where the inclination of the guide rails to the vertical exceeds 15°:
4. lifts with drives other than traction drives or positive drives:
5. like-for-like replacement of lift components (see 3.2):
6. goods only lifts.

NOTE 1 The recommendations in this part of BS 5655 may, however, be used as abasis formodernization or modification of such lifts.

NOTE 2 Where a lift falls into one of the following categories, it is deemed to be a new lift as defined in the Lifts Regulations 1997 [1] and this part of BS 5655 is not applicable:

• dismantled from an existing site and installed at a new site:
• installed where no lift previously existed:
• completely replaced:
• only retains the guide rails.

NOTE 3 In some situations (e.g. potentially explosive atmosphere, extreme climate conditions, vandalism, transporting dangerous goods, etc.), additional measuresmight need to be taken to those recommended in this part of BS 5655.
