Advantages of the rope drive.
The belts or ropes are used to transmit power from one shaft to another by means of pulleys which rotate at the same speed or at different speeds.
The belts or ropes are used to transmit power from one shaft to another by means of pulleys which rotate at the same speed or at different speeds.
1 is mostly used in the factories and workshops where a great amount of power is to be transmitted from one pulley to another when the two pulleys are more than 8 metres apart.
