Abstract
A railcar dumper system utilizes a trunnion wheel assembly to support a rotary rail car dumper having a rotary frame assembly supported by at least four trunnion wheel assemblies positioned along the ends of the rotary frame assembly. Each trunnion wheel assembly includes an equalizer bracket and a pair of trunnion wheel units selectively connected and disconnected from opposite ends of the equalizer bracket. Each trunnion wheel unit has a respective trunnion wheel bracket supporting a respective trunnion wheel that rotates within the trunnion wheel bracket. An equalizer support pivotally connects to the equalizer bracket between the opposite ends.
Claims20
A trunnion wheel assembly comprising:
- an equalizer bracket;
- and
- a trunnion wheel unit comprising a trunnion wheel bracket supporting a trunnion wheel that rotates within the trunnion wheel bracket;
- wherein the trunnion wheel unit is configured to be selectively connected and disconnected from the equalizer bracket.
A trunnion wheel assembly comprising:
- an equalizer bracket;
- a trunnion wheel bracket defining a wheel pin passageway there through, said trunnion wheel bracket configured to selectively connect and disconnect from said equalizer bracket;
- wherein in a connected position, said equalizer bracket and said trunnion wheel bracket define a trunnion wheel cavity therein.
A railcar dumper system comprising:
- a rotary rail car dumper supported by at least four trunnion wheel assemblies, each trunnion wheel assembly comprising:
- an equalizer bracket;
- a pair of trunnion wheel units selectively connected and disconnected from opposite ends of the equalizer bracket, wherein each trunnion wheel unit comprises a respective trunnion wheel bracket supporting a respective trunnion wheel that rotates within the trunnion wheel bracket;
- and
- an equalizer support pivotally connected to said equalizer bracket between said opposite ends.
A method of connecting a trunnion wheel within a trunnion wheel assembly, the method comprising:
- assembling a trunnion wheel unit by securing the trunnion wheel within a trunnion wheel bracket such that said trunnion wheel rotates about a wheel pin connected across the trunnion wheel bracket;
- securing the trunnion wheel unit to an equalizer bracket on the trunnion wheel assembly such that the trunnion wheel rotates about the wheel pin within a trunnion wheel cavity defined by said trunnion wheel bracket and said equalizer bracket,
- wherein the trunnion wheel unit is configured to be selectively connected and disconnected from the equalizer bracket.
