FIELD: transport engineering. SUBSTANCE: semitrailer frame is made in form of stepped weldment resting on three-axle bogie arranged in rear part of frame. Frame has main sidemembers 2 and additional sidemembers 3. Additional sidemembers 3 are reinforced in upper parts by angle members 5. Ends of vertically arranged webs of angle members 5 are rigidly coupled with upper webs 7 of additional sidemembers 3, and horizontal webs of angle members 5 are rigidly coupled with crossmembers 4 arranged in front part of frame and are rigidly connected by ends with middle parts of inner surfaces of walls of additional sidemembers 3. Placed between main sidemembers 2 under crossmembers 4 are reinforcement members 10 made in form of U-shaped section beams. Reinforcement members 10 are arranged symmetrically relative to longitudinal axis of frame, in parallel with main sidemembers 2. Semitrailer lighting and brake system lines are laid inside reinforcement members 10. Semitrailer frame has additionally two cross beams 14 intended for mounting containers. Locking devices are fitted on end faces of cross beams 14. EFFECT: enlarged operating capabilities. 6 dwg
