Abstract: A lift mechanism is provided for lifting the tow bar of a trailer to facilitate connection of the trailer tow bar to a truck's pintle. In the preferred embodiment the lift mechanism includes a bladder which may be connected to a pneumatic system on the trailer. The air bladder is inflated to raise the tow bar above the level of the pintle, facilitating connection of the tow bar to the pintle. Because the tow bar is independent of the lift mechanism, the tow bar has a free travel range greater than the powered travel range.

Abstract: An automatic, pneumatically operated flatrack lockdown device is provided for a palletized load system trailer. The lockdown device includes a manual release system which can override the pneumatic system when, for example, the pneumatic system fails. The release system includes a main handle, which when pivoted unlocks the flatrack. In one embodiment, the release system further includes a locking assembly which prevents the main handle from unlocking the flatrack , and a pair of release handles, each of which release the locking assembly to allow for operation of the main handle.

Abstract: A device for testing two way radios, particularly Citizen Band mobile transceivers, includes a console with a front panel having meters for displaying rf power, percent modulation, rf voltage, transceiver output frequency, DC voltage and AC voltage, a channel selector for testing various channel frequencies and a signal level adjust knob permitting receiver sensitivity testing, a test sequence selector for controlling operation of the device in self test, transmit test and receive test modes, a coaxial connector for receiving an antenna connector of a transceiver to be tested, and AC and DC power hookup sockets.
