Abstract
A control system for a container chassis latching assembly of a trailer provides for initial pressurization of the latching assembly via the trailer supply line. Once a trailer reservoir is sufficiently charged, pressure is maintained for the latch assembly by the trailer reservoir. A preferred control valve interconnects the supply line with a supply port of the valve to provide the desired pressure at a delivery port. A control port of the valve is connected with the trailer reservoir and shuts off this flow once the trailer reservoir has reached a predetermined pressure. Thereafter, the latch assembly is maintained via air supplied from the trailer reservoir.
Claims22
A trailer container chassis latching system comprising:
- a supply line adapted for connection with a trailer supply line:
- a trailer reservoir for storing compressed air for trailer use;
- a latching assembly for connecting a trailer container to a trailer chassis;
- and
- a valve in operative communication with the supply line, the trailer reservoir, and the latching assembly, wherein the valve is adapted to initially supply air from the supply line to the latching assembly and then supply air from the trailer reservoir to the latching assembly once a predetermined pressure is attained in the trailer reservoir.
A method of controlling a trailer container chassis latching system which includes a supply line, a trailer reservoir, and pneumatic latching assembly comprising the steps of:
- initially connecting the supply line to the latching assembly;
- charging the trailer reservoir;
- and
- interconnecting the trailer reservoir with the latching assembly once the trailer reservoir reaches a predetermined pressure level.
A control system for a container chassis latching assembly of a trailer comprising:
- a tractor supply line adapted for operative connection with a trailer supply line to provide compressed air to the trailer;
- a trailer reservoir mounted on the trailer for storing compressed air for trailer use;
- a pneumatic reservoir mounted on the trailer for storing compressed air for trailer use;
- a pneumatic latch assembly for securing the trailer container to an associated trailer chassis;
- and
- a control valve of selectively interconnecting the latch assembly to one of the supply line and the trailer reservoir whereby the latching assembly is initially connected to the supply line and subsequently connected to the trailer reservoir once a predetermined pressure is reached in the trailer reservoir.
A trailer container chassis latching system comprising:
- a supply line in connection with a trailer supply line;
- a trailer reservoir for storing compressed air;
- a latching assembly for securing a trailer container to a trailer chassis;
- a valve in operative communication with the supply line, the trailer reservoir, and the latching assembly;
- and
- an actuating member interposed between said valve and said latching assembly for selectively applying and releasing the latch assembly, wherein said actuating member is connected to spring brakes such as to actuate the spring brakes upon the release of the latch assembly.
