  • Patent number: 6050762

To accomplish this the pinlock device has a housing adapted to be fixed to said front bolster beam. A first side wall having a slot which extends away from the front bolster beam and the locking pin is slidably engaged in the housing. A handle is fixed to the locking pin slidable in the first slot. A latch having a second slot is rotatably engaged to said side wall and the handle extends through the second slot. When the locking pin is engaged to the freight container the gravity latch maintains the handle in a locked position when the device is fixed at either end of said front bolster beam, in spite the fact that the devices are rotated 180 degrees in relation to each other to their operational position with the handles pointing towards each other.
