Abstract: A delimiter that can be arranged along the sides of a runway. The delimiter can be locked in an upright position for most normal operations. When the runway must be cleared of snow, an operator can lower the delimiters in place, either manually or by motor. After the runway has been cleared of snow, the delimiters can be raised again for use. Unlike the delimiters described above, these delimiters meet all aircraft regulation requirements. When collapsed, they do not protrude above the surface of the ground. The delimiters also have a shear mechanism that allows the raised portion of the delimiter to break off when struck. This shear mechanism protects aircraft by breaking away the upper portion of the delimiter.

Abstract translation: 可以沿着跑道的侧面布置的分隔符。 为了大多数正常操作，分隔符可以锁定在直立位置。 当跑道必须清除雪时，操作员可以手动或通过电机将分隔符降低到位。 在跑道已经被清除之后，分隔符可以再次被提起使用。 与上述分隔符不同，这些分隔符符合飞机规则要求。 当它们塌陷时，它们不会突出在地面以上。 分界符还具有剪切机构，其允许分隔符的凸起部分在撞击时中断。 这种剪切机构通过分离分隔符的上部来保护飞机。
