(1) The mine operator of an underground mine must ensure every winding system used or that may be put into use at the mine includes the following—

(a) ropes and devices that can withstand all forces reasonably expected to be borne by the ropes and devices,

(b) control measures to prevent, as far as reasonably practicable, a shaft conveyance from overwind, moving at an unsafe speed, excessive acceleration and deceleration and uncontrolled movement,

(c) at least 2 braking systems that—

(i) ensure the winding system remains under control in the event of a failure in 1 of the systems, or

(ii) for a winding system used or that may be put into use at a small gemstone mine—are designed to incorporate a fail safe and consist of at least 1 brake and 1 emergency arresting device,

(d) a device that safely attaches ropes to conveyances,

(e) for an underground small gemstone mine, control measures that detect one or more of the following malfunctions that may be present—

(i) slack rope,

(ii) broken rope,

(iii) rope detaching from a conveyance or winding drum,

(iv) unsafe coiling of rope,

(f) for an underground mine other than a small gemstone mine, control measures that detect 1 or more of the following malfunctions that may be present—

(i) slack rope,

(ii) rope slip,

(iii) unsafe balance rope conditions,

(iv) unsafe coiling of rope,

(g) control measures that cause the winding system to be brought to a safe state when a condition or malfunction referred to in paragraph (e) or (f) is detected,

(h) warning systems to alert persons at the mine to an emergency in a winding system,

(i) if it is reasonably practicable, remote monitoring of the functions of the system,
