Post removal device
Abstract:
A post removal device (10), including a support (11), and a lever (12) which is rotatable about a fulcrum (13). The lever (12) extends on either side of the fulcrum (13) to define a first portion (14) and a second portion (15), whereby downward movement of the first portion (14) results in upward movement of the second portion (15). The second portion (15) is connected to a gripping arrangement (19) which includes a pair of post grippers (23), which are movable during rotation of the lever (12), from an open condition to a gripping condition. The extent of rotational movement of the lever (12) is sufficient for the grippers (23) to move from the open condition to the gripping condition and for the gripping arrangement (19) to be lifted with the grippers (23) in the gripping condition for lifting a post.
