In view of the foregoing disadvantages inherent in the known types of lid systems of known designs and configurations now present in the prior art, the present invention provides an improved dumpster lid opening system. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved dumpster lid opening system and method which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises a dumpster lid opening system. First provided is a container. The container has a rectangular horizontal base plate. The container has a rectangular vertical front wall. The container has a rectangular vertical rear wall. The container also has vertical first and second side walls. The side walls are provided parallel to each other. The side walls are generally rectangular. The side walls, the front wall and the rear wall each have an upper edge. The front and rear walls have a height. The rear wall height is greater than the front wall height. The upper edges of the side walls are angled downwardly from the upper edge of the rear wall to the upper edge of the front wall. In this manner a chamber is defined between the walls. The chamber has an open top.
A first lid is provided. A second lid is also provided. The second lid is configured similarly to the first lid. A first hinge is provided. The first hinge is located above the rear wall adjacent to the first side wall. The first lid is pivotably coupled to the first hinge. A second hinge is provided.

Each pivot bar has a long extent. The long extent is attached to an associated lid. Each pivot bar has a short extent. The short extent extends upwardly from the long extent at an angle of about 30 degrees, plus or minus 10 percent.
Further provided is a first actuator housing. The first actuator housing is secured to the front wall of the housing adjacent to the first lid. A second actuator housing is also provided. The second actuator housing is secured to the front wall of the housing adjacent to the second lid. A first trolley is provided. The first trolley is provided in the first actuator housing. The first trolley has four wheels. In this manner the trolley may be moved between a top rest position and a bottom operational position. A second trolley is provided. The second trolley is provided in the second actuator housing. The second trolley has four wheels. In this manner the trolley may be moved between a top rest position and a bottom operational position. First and second springs are provided. In this manner the first and second trolleys are urged to their top rest position. First and second pedals are provided. The first and second pedals are coupled to first and second trolleys. A tension coil spring is provided. The first and second pedals are adapted to be depressed by a user against the urging of the tension coil spring to the bottom operational positions. The first and second pedals are adapted to be pivoted to a horizontal operative position by a foot of the user. Fixed and rotatable stop shoulders are provided. In this manner to rotation of each pedal upon reaching horizontal is limited. Further in this manner continued pressure by the foot of the user lowers its associated trolley and stretches its associated spring. First and second upper sprockets are provided.
