The invention relates to the technical field of cranes, and provides a low-speed four-wheel trolley device. The low-speed four-wheel trolley device comprises a trolley frame, an open gear system, a driving device and wheel sets symmetrically arranged on the two sides of the open gear system. The wheel sets and the open gear system are arranged in the trolley frame. The wheel sets comprise the driving wheel set and the driven wheel set. The driving wheel set comprises a driving wheel, a wheel gear and a driving wheel axle. The driving wheel is arranged on the driving wheel axle, and the wheel gear is arranged on the driving wheel. A driven wheel of the driven wheel set and the driving wheel are arranged on a trolley track in a cooperation manner. The open gear system comprises a small gear shaft, a first small gear, a large gear and a second small gear. The driving device is arranged at one end of the small gear shaft, and the first small gear is arranged at the other end of the small gear shaft. The first small gear is engaged with the large gear. The large gear and the second small gear are coaxial. The second small gear is engaged with the wheel gear. The low-speed four-wheel trolley device can improve the bearing capacity of a trolley.
