3 Axle Lowboy Gooseneck Trailer for Sale and will be sent to Namibia
Namibia customer is a friend of our Facebook. The customer contacted us on Facebook in July 2020 and asked us for a semi-trailer that can transport large machinery. The customer said that he has seen a lot of semi-trailers about TITAN and probably needs a lowbed semi trailer for his business. According to his needs, we compared the lowbed trailer with the lowboy gooseneck trailer and introduced more details to the customer. After careful consideration, we find that a lowboy gooseneck semi trailer is more suitable for the customer. So the customer finally choose the lowboy gooseneck trailer for sale.
Mechanical detachable gooseneck structure principle
The mechanically detachable gooseneck frame is similar to the lowboy gooseneck trailer body frame, and both are symmetrical with respect to the longitudinal vertical center plane. And indirectly contact with the ground (supported by the ground). The front end of the gooseneck is connected with the traction saddle of the tractor through a traction pin. The relationship between the tractor and the gooseneck is that the tractor can rotate around the blood axis relative to the gooseneck. After being separated from the towing saddle, the tractor can be driven away from the semi-trailer.
The part of the tractor and the traction saddle (or becomes part of the traction saddle) is often made into inclined planes 1 and 2 with different inclination angles that tilt backward and downward with respect to the ground. The front end of the lowboy gooseneck trailer body Tilt the plane forward and downward to align with the upward tilting plane at the lower end of the gooseneck. This structure is arranged after the gooseneck is in direct contact with the semi-trailer. A continuous contact plane can be provided between the two. In order to further cooperate and connect the two.
The front end of the lowboy gooseneck trailer body is adjacent to the rear end of the dumping plane with a slot, the size of which is just enough to allow the protruding rod at the rear end of the gooseneck to be inserted. The convex rod not only includes a supporting neck. It also includes a freely extending raised portion. Its shape is L. shape. The protruding rod can be in adjacent contact with the limit stop block which is stolen orthogonally on the semi-trailer body. The position of the protrusion can be defined by an orthogonal pin at the front end of the material surface.
The function of the compression spring between the pin head and the fixed connecting plate is to restrict the protrusion from moving longitudinally along the semi-trailer. Prevent the gooseneck from detaching from the lowboy gooseneck trailer. The tail of the bolt is hinged to the connecting rod and then to the horizontal rocker through the connecting rod. The horizontal rocker is then hinged with the vertical rocker. Therefore, the latch can be retracted by pulling the handle at right angles to the vertical rocker manually (through the circular notch on the side of the car body).
In order to remove the obstacles to the longitudinal and longitudinal movement of the protrusion, when the handle is rotated counterclockwise, the latch is released under the pull of the horizontal rocker and moves away from the center. The protrusion at the end of the protruding rod moves backward toward the limit stop, and is retracted by pressing the inclined surface of the latch, and finally contacts and presses the limit stop. After that, the bolt springs back under the action of the compression spring and prevents the protrusion from moving out: in this way, the gooseneck and the semi-trailer are bolted together and become a whole, which can move back and forth and laterally.
