The invention discloses a heavy type free shuttling trolley with tracks. The heavy type free shuttling trolley comprises a main track, a
branch track, a main line rack, a
branch line rack, a movable rack, a traveling driving mechanism, a reversing lifting mechanism, a switch-over driving mechanism, a main line trolley support, a
branch line trolley support, a main line traveling wheel, a
branch line traveling wheel and a driving gear. The main track and the branch track are perpendicular with each other in crossing mode, the main line rack and the
branch line rack are arranged on track bases of the main track and the branch track respectively, a movable track and the switch-over driving mechanism are arranged at a crossing node position of the main track and the branch track, and the movable rack is driven by the switch-over driving mechanism and is in
butt joint with the main line rack or the
branch line rack. The main line trolley support and the branch line trolley support are stacked together to form the trolley, a main line traveling wheel and a branch line traveling wheel are arranged on the lower portion respectively, and the reversing lifting mechanism is arranged between the main line trolley support and the branch line trolley support and used for conducting relative lifting so that the main line traveling wheel is matched with the main track or the branch line traveling wheel is matched with the branch track. The traveling driving mechanism is arranged on the trolley so that the driving gear is matched with the main line rack, the branch line rack or the movable rack. The heavy type free shuttling trolley is suitable for material conveying, economical, reliable and high in efficiency.
