Structural Strength & Welding Quality
The bending moment is greatest and the stress is highest when the boom is nearly horizontal.
Smooth retraction indicates:
Sufficient strength of the boom steel
Rational welding and structural design
High precision of pins, sliders, and guide rails
This is a demonstration of real capability, not something that can be exaggerated with specifications.
Hydraulic System and Proportional Control Capability (Core Technology)
This type of movement places extremely high demands on the hydraulic system:
The cylinders must be controllable and free of vibration.
The proportional valves must respond precisely.
The hydraulic circuit design must be impact-resistant.
This demonstrates:
Not just "ability to move," but "controllable movement."
Stability and Safety System Coordination
LMI (Load Moment Indicator)
Overload protection
Outrigger force feedback
