Maximum man-winding speeds

The maximum speed of man-winding in any shaft shall not exceed the values as given below:

In case of sinking shaft, the maximum man-winding rope speed shall not exceed 1.5 m/sec for depths up to 150 metres, 2.5 m/sec for depths from 151 metres to 500 metres
and 3 m/sec for depths exceeding 500 metres. Note: The maximum speeds for man winding in coal mines recommended in view of shaft conditions and functioning of automatic

contrivance, however the speed shall be fixed by the mines manager in consultation with engineer, but shall not exceed above mentioned maximum speeds to avoid over- winding/hard-landing.
