The DRH electric wire rope hoists and related trolleys and accessories have been designed and manufactured using
the most modern technical knowledge and can be used safely.
The dangers for persons working with the hoists can be totally eliminated and/or notably reduced only if the hoist is
used by authorised staff who are appropriately trained and sufficiently prepared in accordance with the instructions
in this documentation.
Completing the hoist with any missing parts (electric controls) so as to conform to current legislation.
Setting up the hoist and, the managing of its functioning.
Execution of operations of different kinds on the hoist particularly in relation to maintenance, the checking and the
repair of any of its components before starting up the machine, during its functioning or also after it stops.
Staff must be completely informed about the potential dangers in the execution of their duties, both regarding the
functioning and the correct use of safety measures available on the machine.
These staff must, moreover follow the safety regulations carefully, as described in this chapter, to prevent dangerous
situations occurring.
3. - SAFETY AND ACCIDENT PREVENTION
