6.2 SCOPE

This section of the code covers power operated hoists, which may be fitted with short link chain or steel wire rope and which are used for vertical lifting and lowering operations only. It therefore excludes winching or pulling applications.

In the case of chain hoists, it is limited to hoists designed so that the chain passes over a pocketed wheel, the slack chain may then hang freely or be stored in a chain collecting box. In the case of wire rope hoists, it is limited to hoists designed so that the wire rope winds on and off a drum upon which it is stored. Units which employ roller chain drives or wire rope friction drive systems are excluded, although these may have much in common with the items covered by this section.

This section of the code mentions power operated hoists with travelling trolleys. The hoist may be ‘combined’ with the trolley or ‘suspended’ from the trolley by its upper terminal fitting, which may be a hook, eyebolt or similar. No specific guidance is given with regard to trolleys. For information on the safe use of travelling trolleys, see SECTION 8 of this code.

This section of the code mentions certain accessories, such as slack chain collecting boxes and power feed systems, but no specific guidance is given in respect of these. For further information reference should be made to 1.A6 APPENDIX 6 - PRINCIPLES FOR THE SELECTION AND USE OF LIFTING APPLIANCES of this code.

This section of the code does not cover ‘people carrying’ applications.
