Gooseneck Trailer with Coupling Link Actuators

摘要

Trailer with a detachable gooseneck having a deck supported toward the rear by ground engaging wheels, mating surfaces on the gooseneck and the deck which abut against each other when the gooseneck is attached to the deck, coupling pins extending along spaced apart, parallel axes from the gooseneck and the deck on opposite sides of the abutting surfaces, a coupling link movable along the pin on the gooseneck between a first position in which the link engages the pin on the deck and a second position in which the link is disengaged from the pin on the deck, and an actuator for moving the coupling link between the first and second positions. A latch hook is rotatively mounted on the deck to the rear of the abutting surfaces for engagement with a laterally extending latch bar which depends from the gooseneck, and a pneumatic actuator is operatively connected to the latch hook for moving the latch hook into and out of engagement with the latch bar.

1. A gooseneck trailer comprising a deck, a gooseneck, coupling pins extending along spaced apart, parallel axes from the gooseneck and the deck, a coupling link movable along the axes between a first position in which the link engages the pins on both the gooseneck and the deck and a second position in which the link engages only one of the pins and is disengaged from the other, and an actuator for moving the link between the first and second positions.
