发明名称 Base for use with a pole puller
摘要 A base ( 108 ) for supporting a pole puller ( 110 ) utilized to manipulate a pole ( 186 ) includes first and second bearing arms ( 112, 114 ) configured to rest on a surface ( 60 ) with the pole ( 186 ) located between the first and second bearing arms ( 112, 114 ). A cross member ( 128 ) interconnects the first and second bearing arms ( 112, 114 ) and a housing ( 138 ) extends from the cross member ( 128 ) into which the pole puller ( 110 ) is seated. A flexible member ( 62 ) coupled to a ram ( 174 ) of the pole puller ( 110 ) encircles the pole ( 186 ). An upward force ( 72 ) is imposed on the flexible member ( 62 ) via the ram ( 174 ) to extract the pole ( 186 ) from a fixed, upright position in the ground ( 60 ). The support provided by the base ( 108 ) prevents the pole puller ( 110 ) from kicking into the ground as the upward force ( 72 ) is imposed.
