Unless the section isolator is adjacent to the main isolator, the location of the main isolator shall be clearly indicated near the section isolator. Where, because of the redundancy of the continuity and moment capacity noted above, a member could be removed without occasioning the structure to cease its intended service, and such removal or loss could be evident in a casual inspection, the structure is fail-safe.

The clips sa be arranged in pairs located on opposite sides of each side of the crane rail and spaced at centres not greater than mm, or as recommended by the competent person or manufacturer. The magnet cable shall be rigidly attached to the bottom block by a suitable cable clamp at a point just above the magnet coupling.
