低矮脚手架螺旋千斤顶需要约 1 英尺加长件

来源证据

提问者在农村住宅草地上使用 3 英尺低矮脚手架时，因脚手架偏矮或地面不平，螺旋千斤顶够不到；已用木块或混凝土块垫高，但认为垫块过度，想知道是否有约 1 英尺的加长方法。

For low-risk, unregulated applications, such as 3-ft scaffolding on grass at a rural home: Is there a way to make 1-ft extensions for scaffolding screw jacks? When the scaffolding is just a bit too short, or for uneven ground where the jack doesn’t reach far enough down. Wood or concrete blocks can be used to gain a few inches. But there’s a point where blocking seems excessive, and an extension might be a better option, in some cases.
