Abstract
A coupler assembly ( ) is suspended from a forward section ( ) of a boom ( ) that projects from a mobile base ( ). An upper end portion ( ) of a pipe piling (P) is gripped by a pair of clamp jaws ( ). The clamp jaws ( ) are movable together and apart and they are mounted for rotation around a common axis. This allows an end portion ( ) of a pipe piling (P) to be gripped by the clamp jaws ( ) while the pipe piling (P) is in a substantially horizontal or some other non vertical position. Then, the coupler assembly ( ) can be lifted to lift the gripped end portion ( ) of the pipe piling (P) upwardly. As end portion ( ) moves upwardly, the clamp jaws ( ) will rotate in position so as to enable the pipe piling (P) to swing upwardly while its lower end is on a support surface. The rotation of the clamp jaws ( ) will continue until the pipe piling (P) is suspended from the lifting boom section ( ) and is in a substantially vertical orientation.
