This utility model relates to a split-type counterweight frame, comprising an upper counterweight assembly and a lower counterweight assembly. The lower part of the upper counterweight assembly and the upper part of the lower counterweight assembly are detachably connected by channel steel. Both sides of the upper and lower counterweight assemblies are straight beams, with counterweight bars located between the two straight beams. A rectangular slot is provided on one side of the upper part of each straight beam, allowing the counterweight bar to enter between the two straight beams from one side. The straight beams have connecting holes at the upper and lower parts of the rectangular slots for connecting slot baffles. The upper beam of the upper counterweight assembly is bolted to the upper part, and the lower beam of the lower counterweight assembly is bolted to the lower part. This utility model is ingeniously designed. By rationally arranging the positions of the straight beams and channel steel, when the weight of the counterweight bar reaches the limit of the straight beam, the weight of the counterweight bar can be increased by adding more straight beams without replacing them with longer straight beams, thus making rational use of space.
