1. A remote manhole cleaning and coating system to clean and coat an interior of a manhole, comprising:
a trailer having a bed;
a main bracket having a first end pivotally connected to a rear portion of the trailer, wherein the main bracket has a stowed position and an operating position, wherein the main bracket extends outwardly from the rear portion of the trailer when in the operating position and wherein the main bracket extends upwardly when in the stowed position;
a first actuator having a first end pivotally connected to the trailer and a second end pivotally connected to the main bracket, wherein the first actuator is adapted to move the main bracket from the stowed position to the operating position;
a mounting bracket pivotally connected to a second end of the main bracket, wherein the second end of the main bracket is opposite of the first end of the main bracket;
a second actuator having a first end pivotally connected to the main bracket and a second end pivotally connected to the mounting bracket, wherein the second actuator is adapted to move the mounting bracket from a stowed position to an operating position; and
a manhole cleaning and coating assembly that is connected to the mounting bracket, wherein the main bracket moves the manhole cleaning and coating assembly between a stowed position for transport and an operating position for remote cleaning and coating of the manhole.
