BS 5655-6:2002 pdf download – Lifts and service lifts — Part 6: Code of practice for the selection and installation of new lifts
The rated load should range from 320 kg to 2 500 kg and the rated speed should range from 0.4 m/s to 1.0 m/s for hydraulic lifts and 0.63 m/s to 6.00 m/s for electric traction lifts. Higher speeds are currently available, but should be discussed in detail between the lift contractor and the purchaser’s representative. If the projected installation is one ofthe arrangements described above, the following guidance will enable the preliminary scheme for the installation, in particular the traffic sizing (see Clause 6), to be established, and general planning details to be determined by the architect, or any person assuming such function. These details should be finally settled at the earliest possible stage, by a detailed investigation, with the purchaser’s representative reaching agreement with the lift contractor, where necessary, before an order is finalized. This will enable a check to be made that all the necessary information has been exchanged. NOTE A typical checklist of the information to be exchanged is shown in B.1.
4.2 Lift enquiry or invitation to tender
4.2.1 General The purchaser’s representative should allow adequate time for the lift contractor to tender. A period of 4 weeks to 8 weeks is generally sufficient, dependent on the complexity and size of the scheme. The enquiry documents should be strictly confined to material relevant to the lift work and the particular project. The enquiry documents should state the particular project and the standards to which the equipment has to conform. Extracts from standards and regulations should not be quoted in the enquiry documents. NOTE 1 Attention is particularly drawn to the Lifts Regulations 1997  with regard to new lifts. NOTE 2 A typical checklist of the information to be exchanged is shown in B.2.1. When building restrictions, or special types of load, preclude the use of lifts conforming to the relevant requirements of BS EN 81-1:1998 and BS EN 81-2:1998, additional data should be included in the enquiry documents as necessary, according to the particular circumstances.
NOTE 3 Attention is drawn to the Lifts Regulations 1997 , which require a Design Examination Certificate to be obtained under certain circumstances.
NOTE 4 Attention is drawn to the Disability Discrimination Act 1995 . See Clause 10 and A.4.
4.2.2 Additional items The enquiry documents should indicate any additional items beyond those required by BS EN 81-1 and BS EN 81-2, such as dismantling of an existing lift, vision panels, forced ventilation, landing architrave, telephone, level of fire resistance, any special controls, fire-fighting lifts and designations (see 7.2.3) and any beneficial use (see 4.5.4).
Where applicable, the principal contractor should specify the building construction for the well and machine room, provide notes on possible fixings for guides, etc., and indicate any special installation method for the lift that might be required on system building sites (see 4.4.8). NOTE 1 This can necessitate agreement between the principal contractor and the lift contractor before a tender can be submitted. NOTE 2 Annex C gives guidance regarding interface fixings for steel-framed buildings.
Lifts to be installed in adverse conditions, e.g. chemical works, lifts used with power trucks and lifts used in vandal-prone situations (see BS 5655-13) and similar applications, require special consideration according to the circumstances.
Finishes should be specified at the enquiry stage. See also 4.3.5.
NOTE 1 A list of possible finishes is given in B.2.2.
NOTE 2 Attention is drawn to the Disability Discrimination Act 1995 . See Clause 10 and A.4.
4.2.4 Other items A number of other items are associated with a lift installation, of which some should normally be provided by the principal contractor and some should normally be provided by the lift contractor. The items vary with the type of installation. It is important that the limits of responsibility are clearly understood by all parties, particularly with respect to design and build projects, and the enquiry documents should be specific in this respect.
