The invention discloses a crane trolley. The crane trolley comprises a trolley frame and a sling rack extending in the left-and-right direction, wherein two roller trains are arranged at the left end and the right end of the sling rack; each roller train comprises a front roller and a rear roller; two guide tracks are fixedly arranged on the trolley frame; the guide tracks are provided with front track faces and rear track faces, which are distributed in the fore-and-aft direction and are respectively and correspondingly in rolling fit with treads of the front rollers and the rear rollers in corresponding roller trains so as to limit the sling rack in the fore-and-aft direction; planes on which the front track faces of the guide tracks are positioned and the planes on which the rear track faces of the guide tracks are positioned intersect with each other; the two track faces of one of the two guide tracks respectively face to the left front direction and the left rear direction, while the two track faces of the other guide track respectively face to the right front direction and the right rear direction. Reacting forces exerted on the sling rack by the front track faces and the rear track faces of the two guide tracks can limit and lock the sling rack in the fore-and-aft direction and the left-and-right direction, the adaptation structure is relatively simple and the production and manufacture are relatively convenient.
