Abstract: A flange manipulating device for installing and removing flanges includes a bar that is flat. Each of a pair of first holes that is positioned through the bar is positioned proximate to a respective opposing end of the bar. A coupler is coupled to and centrally positioned on the bar. Each first hole is configured to selectively align with a respective second hole that is positioned in a flange. The first hole and the respective second hole are configured to insert hardware, such as a bolt to couple to a nut, to couple the bar to the flange. The coupler is configured to couple to a tool, such as a wrench, to position the tool to selectively applying torque to the bar. The bar is configured to transfer the torque from the tool to the flange to selectively install the flange on and remove the flange from a threaded pipe.

Abstract: A hopper assembly for a ready mixed concrete truck having a material off loading position and a material on loading position. The hopper assembly includes a main chute portion and a movable portion movable between an open position for off loading and a closed position for on loading. The movable portion directs material directly into an opening of a mixing drum providing for the rapid on loading from an overhead delivery apparatus when in the closed position. When the movable portion is in the open position or off loading position a passage area between the hopper assembly and the mixing drum is increased thereby eliminating a restricted area to provide for the effective dispensing of high viscosity material such as low slump concrete.
