10.5.5 General Considerations
Other matters which should be taken into consideration when selecting slewing jib cranes include:
If power operated hoists are to be used, the availability of a suitable power source should be considered and this must include provision for isolating the jib crane and hoist from the power supply. It should be noted that most free standing jibs designed for use with power operated hoists will be supplied complete with all necessary power supply systems terminating at an isolator mounted on the column.
The jib arm (runway) must be fitted with positive travel stops to prevent the trolley running off the end or colliding with the bracing or supporting structure. Consideration should be given to the position of the inner stops as it may be desirable to limit the travel of the load in certain applications, such as on a production line, or to prevent the load colliding with ground level obstructions.
The finish and protection of the supporting structure should also be considered, as this will usually be supplied primed and painted as standard. Some further finishing may therefore be necessary to protect the crane due to its environment, e.g. outdoor or high humidity, or to protect the goods being handled, e.g. food products.
The jib crane, together with its associated hoist and trolley, should be covered by the documentation required by legislation. If this is not on record refer the equipment to a Competent Person for thorough examination.
