When the system is parked, the upper part of the l-arc was able to touch the cable hose and over time this caused it to slide the cable hose through the hanger.When the cable hose got to a point of being short enough, this caused too much stress on the hanger bolt and it snapped, allowing the cable hose to drop to a height where a person could collide with it.The field service engineer concluded that the cable hose from the stand had moved through the hanger because of careless use by the customer.He replaced the bolt and remounted the cable hose hanger back on the ceiling carriage.The system was returned to the customer in working order.(b)(4).
