TAIL BEAM
Document Type and Number:
WIPO Patent Application WO/2023/093523
Kind Code:
A1
Abstract:
A tail beam comprises a main beam (11), a first support lug group (12), and a second support lug group (13), wherein two ends of the main beam (11) in its length direction are configured to be connected to external leveling support legs; the first support lug group (12) and the second support lug group (13) are of the same structure; the first support lug group (12) comprises a pair of first support lugs (121); slewing bearings (125) are arranged in support lug holes of the pair of first support lugs (121); the first support lug group (12) and the second support lug group (13) are both connected to the main beam (11); a spacing is reserved between the pair of first support lugs (121) and the main beam (11); the first support lug group (12) and the second support lug group (13) are symmetrical to each other with respect to a midpoint of the main beam (11) in the length direction; and the first support lug group (12) and the second support lug group (13) are both perpendicular to the main beam (11). According to the tail beam, when a trailer is loaded with transported objects, the two support lug groups can act as supporting rotation points, such that the filling process is made easier; and the spacing is reserved between each of the two support lug groups and the main beam, such that the tail beam does not interfere with a frame during loading of the transported objects.
