Abstract
A device and method for removing a post. The device includes a housing, at least one stabilizing member and an engagement member. The housing defines a chamber and a lower orifice and is adapted for receiving the post through the lower orifice and into the chamber. The at least one stabilizing member is positioned within the chamber for stabilizing a lateral position of a post received in the chamber. The engagement member is positionable within the chamber and is configured for engaging a portion of the received post within the chamber and biasing the received post against the at least one stabilizing member, responsive, at least in part, to the housing receiving an upward force.
Claims24
A device for removing a post comprising:
- a housing defining a chamber and a lower orifice, the housing adapted for receiving the post through the lower orifice and into the chamber;
- at least one stabilizing member positioned within the chamber for stabilizing a lateral position of the received post within the chamber;
- and
- an engagement member positionable within the chamber and configured for engaging a portion of the post received within the chamber and biasing the received post against the at least one stabilizing member, responsive, at least in part, to the housing receiving an upward force.
A device for pulling posts comprising:
- a housing defining a lower orifice, an upper orifice, and a chamber having a longitudinal axis extending from the lower orifice to the upper orifice, the housing adapted for receiving the post through the lower orifice, into the chamber and exiting the upper orifice;
- a lifting member fixedly attached to the housing for coupling to a lifting device, receiving the upward force from the lifting device, and imparting the received upward force to the housing;
- two or more stabilizing members are positioned within the chamber for stabilizing a lateral position of the received post;
- a pin positioned within the chamber transverse to the longitudinal axis, the pin adapted for pivoting about an axis perpendicular to the longitudinal axis of the chamber;
- a biasing member attached to pin for providing a rotational bias to the pin about its axis;
- and
- an engagement member extending radially from the pin and configured for biased engagement of a portion of the received post and biasing the post into engagement with the two or more stabilizing members responsive to the biasing member.
A device for pulling a post comprising
- receiving means for enclosing the post within a chamber of a housing;
- lifting means for receiving an upward force from a lifting device and imparting the received upward force from the lifting means to the housing;
- stabilizing means for stabilizing and aligning the position of the post within the chamber;
- and
- engaging means for engaging a portion of the post within the chamber and imparting the upward force imparted to the housing to the post.
A method for pulling a post comprising:
- attaching a lifting device to a housing defining a chamber;
- receiving the post within the chamber;
- positioning an engagement member against a portion of the post within the chamber;
- and
- applying an upward force to the housing from the lifting device, wherein the housing, engagement member and stabilizing member cooperate to directly transmit the applied upward force from the housing to the post.
