Fence post extractor
摘要:
A fence post extractor includes a sleeve for receiving a fence post and a clamping bar that is pivotable with respect to the sleeve at a pivot joint. The clamping bar pivots between a first position where the fence post is clamped between a second end of the clamping bar and the sleeve, and a second position where the fence post is released with respect to the second end of the clamping bar. A powered lifting apparatus has an engaging portion that is engaged with the clamping bar. The engaging portion is moved under power between a raised position and a lowered position to move the clamping bar between the first and second positions.
