The invention relates to a trolley capable of reducing friction. The trolley comprises a trolley body and is characterized in that the trolley body is made of square tubes, and a roller assembly is arranged at the bottom of the trolley body; first brackets and second brackets are arranged in the trolley body in sequence from top to bottom in an alternating mode; each first bracket and each second bracket are both formed by two bracket bodies symmetrically located on the left side and the right side of the inside of the trolley body; the second brackets are right angular, clamping grooves are formed in the outer sides of the first right-angle edges of the second brackets and connected with the trolley body, rolling grooves are formed in the upper surfaces of the second right-angle edges of the second brackets, and balls are arranged in the rolling grooves. The first brackets are right angular, the first right-angle edges of the first brackets are fixedly connected with the trolley body, and protrusions are arranged on the upper surfaces of the second right-angle edges of the first brackets and the upper surfaces of the ends of the first brackets respectively. The trolley can solve the friction problem between a baking tray and a trolley support and reduce the disadvantages caused by friction.
