The more you use a wire rope, the more often you need to inspect it. ASME B30 standards state that owners or users must visually inspect all wire ropes at least once every day when in use. Annual inspections shall be by done a qualified person who has learned, through specialized training and practical experience, what to look for and to judge the importance of any abnormal conditions.
The qualified inspector must also periodically inspect all wire rope, and keep a written record, noting any damage, and record when the ropes are replaced.
CICB recommends that you set up a long-range inspection program, including examination of wire rope removed from service. Regular inspections of wire rope and equipment should be performed for the following reasons:
- Inspection reveals the rope’s condition and indicates the need for replacement
- Inspection can indicate if you’re using a suitable type of rope
- Inspection helps discover and correct faults in equipment or operation that can cause costly accelerated rope wear.
Although you are required to inspect the entire rope length, it is highly recommended that you pay attention to the critical points, such as pick points, drums, sheaves, and end attachments. These points are subject to greater internal stresses, greater external forces and are more susceptible to damage.
All wire rope that have been idle for one month or longer should be inspected according to ASME B30 standards, before being put into service.
