Description

Technical Field

[0001] The utility model relates to the technical field of counterweight processing, in particular to a fixture for grinding counterweights. Background Art

[0002] The counterweight is made of cast iron. The counterweight is connected to the frame through the counterweight hanging plate and the vertical plate and installed on the forklift frame. When connected, the inclined surface on the counterweight fits the inclined surface of the counterweight hanging plate, the circular step surface on the counterweight fits the vertical plate on the frame, and the hole on the step surface is concentric with the threaded hole on the vertical plate and connected with bolts to fasten the counterweight to the frame. The counterweight needs to be polished during production.
