Claims20
A hopper railroad car top hatch cover assembly for a hopper railroad car including a roof including an upwardly extending coaming, the hopper railroad car hatch cover assembly comprising:
- a hatch cover pivotally connectable on one side of the coaming and including a movable hatch pivotally movable from a closed position engaging the coaming to an open position disengaged from the coaming;
- a hatch cover securer movably connectable on an opposite side of the coaming and including a hatch cover engager movable from a hatch cover engagement position in which the hatch cover engager secures the movable hatch in the closed position engaging the coaming to a hatch cover non-engagement position in which the hatch cover engager allows the movable hatch to move to the open position;
- and
- a multi-action actuator positioned at a first end of the coaming, the multi-action actuator comprising:
- a first mounting bracket assembly connectable to the hatch cover securer and positioned to move the hatch cover engager between the hatch cover engagement position and the hatch cover non-engagement position;
- a second mounting bracket assembly connectable to the hatch cover and positioned to move the movable hatch between the closed position and the open position;
- and
- a powered cylinder assembly having a first end and an opposite second end, the first end connectable to the first mounting bracket assembly and the second end connectable to the second mounting bracket assembly such that the powered cylinder assembly is between the first mounting bracket assembly and the second mounting bracket assembly, and such that the powered cylinder assembly is actuatable to cause movement of both the first mounting bracket assembly and the second mounting bracket assembly.

- and
- a multi-action actuator positioned at a first end of the coaming, the multi-action actuator comprising:
- a first mounting bracket assembly connectable to the hatch cover securer, the first mounting bracket assembly including a kickstand movable between a kickstand engagement position and a kickstand non-engagement position, the kickstand configured to prevent movement of the first mounting bracket assembly when the kickstand is in the kickstand engagement position;
- and
- a second mounting bracket assembly connectable to the hatch cover, the second mounting bracket assembly including a kicker movable between a kicker engagement position and a kicker non-engagement position, the kicker configured to move the kickstand from the kickstand engagement position to the kickstand non-engagement position.
