### sec.267 Winders and slope haulages The site senior executive for an underground mine must ensure each winder and slope haulage used at the mine complies with this section. A winder or slope haulage used for carrying persons at the mine must have at least 2 independent braking systems, 1 acting directly on the drum. Each brake must be capable, at all times, of— bringing the winder, or haulage, to rest safely; and preventing drum movement, under balanced load conditions, when the maximum torque is applied in either direction. The brakes must be designed and installed to fail to safety. The winder must also have the following— an automatic device to prevent the winder overwinding; a device to prevent the descending conveyance from being landed at the lowest entrance to the shaft at a speed exceeding 3.5m/s; a device to indicate the position of each conveyance in the shaft; for a manually controlled winder the speed of which is capable of exceeding 4m/s—a rope speed indicator located on the winder where the indicator can be read by the operator. The slope haulage must also have the following— an automatic device to prevent over-travel; a device to indicate the position of each rope hauled train of vehicles in the roadway; for a manually controlled slope haulage the speed of which is capable of exceeding 2m/s—a rope speed indicator located on the slope haulage where the indicator can be read by the operator.

(sec.267-ssec.4) The brakes must be designed and installed to fail to safety. (sec.267-ssec.5) The winder must also have the following— an automatic device to prevent the winder overwinding; a device to prevent the descending conveyance from being landed at the lowest entrance to the shaft at a speed exceeding 3.5m/s; a device to indicate the position of each conveyance in the shaft; for a manually controlled winder the speed of which is capable of exceeding 4m/s—a rope speed indicator located on the winder where the indicator can be read by the operator. (sec.267-ssec.6) The slope haulage must also have the following— an automatic device to prevent over-travel; a device to indicate the position of each rope hauled train of vehicles in the roadway; for a manually controlled slope haulage the speed of which is capable of exceeding 2m/s—a rope speed indicator located on the slope haulage where the indicator can be read by the operator. - (a) bringing the winder, or haulage, to rest safely; and - (b) preventing drum movement, under balanced load conditions, when the maximum torque is applied in either direction. - (a) an automatic device to prevent the winder overwinding; - (b) a device to prevent the descending conveyance from being landed at the lowest entrance to the shaft at a speed exceeding 3.5m/s; - (c) a device to indicate the position of each conveyance in the shaft; - (d) for a manually controlled winder the speed of which is capable of exceeding 4m/s—a rope speed indicator located on the winder where the indicator can be read by the operator. - (a) an automatic device to prevent over-travel; - (b) a device to indicate the position of each rope hauled train of vehicles in the roadway; - (c) for a manually controlled slope haulage the speed of which is capable of exceeding 2m/s—a rope speed indicator located on the slope haulage where the indicator can be read by the operator.
