A device enables a sheet pile to be lifted from a horizontal position on the ground to a vertical position in the air, where it can be attached to a vibratory hammer. The device comprises two members, one of which attaches to the sheet pile and the other to the vibratory hammer. The two members are rotatably connected by a spindle, and they can be alternately locked into an extended (straight vertical) or bent (perpendicular) orientation by a lever-actuated spring-loaded key in the lower member that engages one or more slots in the upper member. |
