3.1 FOREWORD
Despite the labour involved in the use of hand operated chain hoists, they remain in wide use throughout industry. They are preferred to power operated hoists for a number of applications, the main ones being as follows:
Where a permanent installation for infrequent use is required.
Where a temporary installation for erection or maintenance purposes is required.
Where precision location of the load is required.
Where a suitable power supply is not readily available.
It can be seen that there is an emphasis on applications involving either long intervals between use or frequent changes of use, both of which require particular vigilance in the in-service inspection procedures to ensure that no significant deterioration or damage has occurred since last used.
All modern hand operated hoists are fitted with an automatic brake which, when functioning correctly, is capable of arresting and sustaining the load at any position. Whilst this code of practice is directed at such equipment, the user may occasionally still come across older equipment not fitted with a brake. If so, they are reminded of their legal obligations to provide safe systems of work, as it is unlikely that such equipment will meet these requirements.
