BS 7981:2002 pdf free.Code of practice for the installation, maintenance, thorough examination and safe use of mast climbing work platforms (MCWPs).
BS 7981 1 Scope This British Standard provides guidance and recommendations for persons responsible for the installation,maintenance and thorough examination of mast climbing work platforms (MCWPs). It also provides
guidance and recommendations on the safe use of MCWPs.
This British Standard gives recommendations for MCWPs, which are temporarily and permanently installed, electrically powered and designed to be used by one or more persons from which to carry out work. The vertical moving components (work platform) are used to move those same persons and their equipment and materials to and from a single boarding point. These restrictions differentiate MCWPs from builder’s hoists.
This British Standard gives recommendations for MCWPs including those that meet the requirements of BS EN 1495. These MCWPs typically can be considered to consist of four assemblies, or groups of parts, as follows.
a) At least one mast which is climbed by and which supports the work platform.
b) A work platform capable of supporting persons, equipment, tools and materials, etc.
c) A wheeled chassis or a base frame supporting the mast structure.
NOTE 1 The chassis or base frame can provide stability for MCWPs up to a predetermined free-standing height, above which the mast(8) is tied to the building or other structure. d) Mast tie assemblies.
NOTE2 Figure 1 shows a single- mast mobile MCWP. Figure 2 shows a twin mast MCWP that for ilustrative purposes shows examples of a fixed base and a mobile base. Twin mast machines on site either have two fixed bases or two mobile chassis’.
Figure 3 shows typical mast tie arrangements.
This British Standard does not give recommendations for dealing with the hazards involved in the
manoeuvring, erection or dismantling, fixing or removing of any materials or equipment which are not part of the mast climbing work platform. Neither does it deal with the handling of specific hazardous materials.This British Standard does not give recommendations for delivering persons and materials to fixed landing.BS 7981 pdf download.
