Specialized crane efficiently removes guardrail poles using innovative extraction technique.

A specialized crane equipped with a pole extraction attachment is efficiently removing hollow guardrail poles from the roadside. The process involves inserting a rod into the hollow opening at the top of the pole, followed by strategically placing wedges on either side of the rod. As the crane initiates the lifting process, the wedges and rod create a tightening mechanism inside the pole, facilitating its extraction from the ground with precision and ease. This innovative technique ensures safe and effective removal of poles for infrastructure maintenance.
