$\color{red}{Construction of DC machine known as Generator}$

✍️The essential parts of DC generator are same as AC generator except the slip-ring arrangements.The slip rings are replaced by commutator R1 and R2 consisting of two halves of same metallic ring. The ends of the armature (A and D ) are connected to these half rings which rotate along with the armature coil.
With this arrangement,one brush is at all times in contact with the arm moving up in the field while the other is in contact with the arm moving down.The direction of current doesn't change in the external circuit,it always flows in the same direction. So, it is direct current.
The generator is thus called a DC generator or machine that produce direct current from mechanical energy.✍️

Explanation:

The construction of a dc generator is identical to that of a dc motor, both physically and electrically.the same machine may be used as motor or generator. Suspended access platform is basically the machinery, equipment, platform or other devices that are suspended by support lines. The workers mostly use this to gain access to the high angle surfaces or sides of structures or buildings. If these devices are used correctly, it helps greatly in doing work. But, there can be a high risk of fatality or injury in case the suspended personnel platform is used incorrectly.
