The invention relates to a vehicle-mounted truss type gantry crane which comprises at least four sections of telescopic truss structures and further comprises a truck (11) used for containing and supporting the telescopic truss structures, a reinforcing truss structure used for reinforcing the overlapped telescopic truss structures and a hoisting trolley (10) used for carrying out hoisting operation. The section size of each section of the telescopic truss structure is sequentially reduced from the first section to the tail section, and the telescopic truss structures can be concentrically placed in the center of the first section structure. The adjacent truss structures are in sliding connection, the (M-1) th section of truss structure is rotationally connected with the Mth section of truss structure, the Nth section of truss structure is rotationally connected with the (N+1)th section of truss structure, and M is larger than 2 and smaller than N-1. Compared with the prior art, the vehicle-mounted truss type gantry crane has the advantages of stronger maneuverability, light dead weight, stronger safety, better structural stability and the like.
