Light carrying trolley

The invention provides a light carrying trolley, and relates to a novel hoisting scheme of a crane. The light carrying trolley is suitable for conducting efficient lifting and obstacle avoidance carrying on heavy objects under complex working environments and conditions; the functions of high efficiency and flexible lifting of the crane are achieved mainly through the system design of the three parts of movement, lifting and clamping; the whole trolley moves through Mecanum wheels and four-wheel drives, and the efficiency is doubled through two sets of lifting systems arranged at a headstock and a tailstock; the lifting action is achieved through a sliding block and lead screw mechanism, and during working, a motor can be self-locked; a grip is opened and closed through a gear and rack mechanism, and thus goods are grabbed; the grip is extended to a certain extent in the longitudinal direction, the tail end is collected to a certain extent, and thus clamping stability and safety are ensured; and as for contro
