The invention discloses a combined symmetrical clump weight for truck-mounted cranes, which comprises a combined middle clump weight, at least one left clump weight and at least one right clump weight, wherein the combined middle clump weight is composed of a bottom clump weight and an upper clump weight, the upper end face of the bottom clump weight is provided with a lug boss, the lower end face of the upper clump weight is provided with a groove matched with the lug boss, the two opposite sides of the upper clump weight are provided with mortises and the other two sides of the upper clump weight are provided with lifting lugs, a mortise and a lifting lug are arranged at the positions, corresponding to the upper clump weight, of the bottom clump weight, the left clump weight and the right clump weight are respectively provided with a hanging lug, and the left clump weight and the right clump weight are respectively butt-jointed and spliced together with the mortise on the bottom clump weight by the lifting lugs. Because an integrally formed clump weight is heavy and is large in volume, great inconvenience is frequently brought to the transportation and installation of the clump weights. According to the weight, through removable arrangement, the demands of truck-mounted cranes with different tonnages can be satisfied by increasing or decreasing the number of the clump weights; and the clump weights are symmetrically arranged, so that the installation and the balancing of the clump weights are convenient, and also the required cost for assembling clump weights in different sizes and shapes can be reduced.
