Answer:
One sheave means that you are using a single drum winder. They are the worst! Double drum winders control easier, brake better and are much more efficient. They save time ( two skips or cages) and can be clutched to perform faster shift transport. A single drum is slow, unbalanced and can be a nightmare if it trips out during hoisting. If the brake system is not perfect it can be a real hairy experience. For a runaway single drum, there is no counterbalance effect. It always runs to destruction. With a double drum, the driver still has a chance to control the winder to a certain extent and he has two sets of brakes to rely on. A single sheave could also mean a shaft with a single compartment. No second means of escape unless there are ladders or stairways. Not a very healthy situation.
Those are just a few points. I am sure much more can be said in favor of a double drum winder and two or more sheaves in the headgear. Most of the shafts I have worked at have multiple winders and up to ten compartments. They all have a small single drum service winder for emergencies and moves of personnel during shift times. They are referred to as the Mary - Annes. Apparently, the name originated in the U.K. where an aristocratic mine owner named the first such winder after his mistress.

The appropriate response is Electrical Switches. These are electromechanical gadgets that are utilized as a part of electrical circuits to control, recognize when frameworks are outside their working reaches, flag controllers of the whereabouts of machine individuals and work pieces, give a way to manual control of machine and process capacities, control lighting, et cetera.

Physical security is very important, but it is not noticed by most organizations.

If this security is not maintained properly all the safety measures will not be useful once the attacker gets through by gaining physical access.
Example of property can be software, equipment, facilities, company’s assets.
