The frame is divided into welding type and assembled type. The small and medium-sized specifications generally adopt the welding type, and the large-scale specifications generally adopt the assembled type.

The welding type adopts large arc transition fillet and low stress area welding method, which has the characteristics of impact resistance, uniform force and low failure rate.

The V-shaped crushing cavity design is adopted, the toggle plate has a large inclination angle and a large stroke. Compared with the traditional PE series jaw crusher, it has the larger feeding particle size, the higher output, more uniform the particle size, and reduced the jaw plate wear.

The integral cast steel bearing seat structure ensures complete coordination with the frame, which makes the bearing run more smoothly and avoids unnecessary radial load on the bearing during the tightening process of the combined bearing seat.

The crusher is fixed by a special rubber shock absorption device, which effectively absorbs the peak vibration of the equipment and allows the vertical and longitudinal displacement of the crusher, thereby reducing the impact on the foundation.
