Paragraph 14

Where mechanically operated winding apparatus is ordinarily used for carrying persons through a shaft in a cage, there shall be provided appropriate gear for detaching each cage from the rope and holding it stationary in the event of over-winding when it is ascending:

Provided that an inspector may by notice served on the manager of the mine exempt any winding apparatus thereat from the requirements of this paragraph.

Where mechanically operated winding apparatus is so used and the speed of winding can exceed twelve feet per second, an inspector by notice served on the manager of the mine may require the provision in connection therewith within such period as may be specified in the notice, and the maintenance, of an automatic contrivance to prevent overwinding.
