The invention discloses a novel building trolley which comprises a trolley body. The lower end of the trolley body is provided with bearing rods. The side faces of the bearing rods are provided with rotary mechanisms, buffering pads and bearings, and the rotary mechanisms, the buffering pads and the bearings are arranged on the same sides of the bearing rods. The bearings are connected with a wheel. The rotary mechanisms are mainly composed of driving rotary wheels, driven gears and fixing rings, and the driving rotary wheels are connected with stainless steel cables and rotary brackets. Plastic special-shaped teeth are mounted on the inner sides of the fixing rings. The stainless steel cables are arranged in rubber sleeves and further connected with rotary handles. According to the novel building trolley, by arranging the rotary mechanisms, the rotary brackets can be easily unfolded and folded according to two different states of parking loading and travelling feeding of the trolley when the trolley is used, the structure is simple but practical, and efficiency of workers during building construction is effectively improved.
