AI Technical Summary
The manufacturing process of loader quick-change devices is complex, the material utilization rate is low, the structural stress is concentrated, the structural weight is large, and the visibility is poor, which leads to high production costs, difficulty in quality control, and increased safety hazards.
The attachment quick-change frame is made of one piece of cast steel. The main frame and the connecting seat are connected by a smooth transition. The design of the T-shaped groove distributes the force and increases the viewing window area. The lightweight design of the whole cast steel parts, combined with the quick-change cylinder and locking pin, realizes quick switching and locking.
It simplifies the manufacturing process, improves material utilization, reduces structural weight, enhances structural strength, expands the field of vision, prevents plate and weld cracking, improves work efficiency and safety, and reduces costs.
