Safety pin - Angel of colision
The safety pin is a crucial element in reducing potential damage, but it is important to note that its mechanism is primarily designed for direct (frontal / normal to the name plate) impacts.
The effectiveness varies on the angle and is greatly reduced if the barrier is impacted from the sides.
In all cases, the force and speed of the object hitting the barrier play a significant role in ensuring the proper breakage of the safety pin. In some cases
that may cause the barrier arm to be pinned to the object and bent even though the safety pin is properly broken.Additionally, the effectiveness of the safety pin depends on the barrier being securely anchored to the ground.There is no specific research available on the maximum safe angle for the breaking of the safety pin.
In instances where impacts occur from the sides, the reliability of the safety pin's breakage may vary.
