Draw the control circuit complete with referencing number and terminal number for an overhead crane according to the sequence described below: Figure 5: An overhead crane • Press pushbutton S1 (N/O), motor will move forward and green pilot light H1 wil turn on for 10 seconds. This is to allow the motor to reach the end limit of the crane. • After the motor reaches the end of travel (indicated by the delay time durations) the motor will stop and red pilot light H2 will turn On. • The control supply for this circuit is 48Vac. • Safety features must be included where: i. The motor must stop at condition the thermal overload relay tripped and an emergency button S2 is pressed.

Types of Braking

A brake is a mechanical device that absorbs energy from a moving system and inhibits its motion. It helps to slow or stop a moving vehicle, axle, wheel, etc. The braking system uses friction between two types of surfaces that are pressed together that convert kinetic energy into heat energy. For instance, we know that in the case of regenerative braking, the brakes convert energy into electrical energy which can be used for later use. The conversion of kinetic heat energy into potential energy is stored in the form of pressurized oil or air. In the brake disc, oil, or fin, the eddy current brakes convert kinetic energy into the electric current with the help of a magnetic field which is converted into heat.Generally, such braking systems apply to the moving axles of wheels. They may also take other forms like moving fluids' surface. In the case of drag racing cars, both wheel brakes are used whereas in parachute or airplanes, both wheel brakes or drag flaps raised in to the air are used.
