Disclosure to Promote the Right To Information

Whereas the Parliament of India has set out to provide a practical regime of right to
information for citizens to secure access to information under the control of public authorities,
in order to promote transparency and accountability in the working of every public authority,
and whereas the attached publication of the Bureau of Indian Standards is of particular interest
to the public, particularly disadvantaged communities and those engaged in the pursuit of
education and knowledge, the attached public safety standard is made available to promote the
timely dissemination of this information in an accurate manner to the public.

FOREWORD

This Indian Standard (Part 1) was adopted by the Bureau of Indian Standards, after the draft finalized by the
Lifts and Escalators Sectional Committee had been approved by the Electrotechnical Division Council.

The standard on this subject was originally published’ as IS 3534 in 1966 and was revised in 1976. This new
—
series of standards is being brought out to reflect the latest trends in lift industry at National and International
level. A detailed study of data collected over a long period has been made before preparing this standard. Every
effort has been made to present the guideline in a simple form and it is hoped that the information furnished
would be helpful to architects, consultants and lift makers.

The net internal areas are kept as close as possible to those specified in 5.1 of IS 14665 (Part 3/See 1): 2000
and width and depth are generally chosen as modular dimensions in steps of 100 mm.

The dimensions given in Table 2 for goods lifts are for normal applications. For special requirements, the design
can be-modified to meet the requirements by mutual agreement between the purchaser and the supplier.

The clear inside dimensions should be measured at a height of one metre from the finished floor of the lift car
from panel to panel.

The pit depth and the dimensions of headrooms suggested in this standard will satisfy all the provisions of 4.5
of IS 14665 (Part 2/See 1) :2000 with regard to clearance and run by for car and counterweight.

The Composition.of technical committee responsible for the preparation of this standard is given at Annex A.

This standard is one among the series of standards finalized by the Lifts and Escalators Sectional Committee as
detailed below. This was done with a view to align the Indian Standards with the latest developments in the field
of Lifts and Escalators and also to align the standards with the European Norms on Lifts and Escalators EN 81.
Moreover, these standards are published with a view to have a uniform code for electric traction lifts all over
the country, where presently different rules are being followed by different states:
