ABSTRACT:
A hydraulic lift attachment is connected to the lift arms of a loading vehicle, and includes a base plate with a pair of brackets thereon for pivotal attachment to the lift arms of the loading vehicle. A first jaw member is rigidly connected to the base plate adjacent one end thereof and projects forwardly beyond the forward edge of the base plate. A second jaw member is operably connected to the base plate for selective pivotal movement about a pivot axis, and also projects forwardly beyond the forward edge of the base plate. The second jaw member is also operably connected for selective slidable movement of the pivot axis towards and away from the first jaw member. A first hydraulic cylinder is connected between an intermediate point on the second jaw and a fixed point on the base plate, so as to pivot the second jaw about a pivot axis. A second hydraulic cylinder is connected between the pivot axis of the second jaw and a fixed point on the base plate, so as to selectively slide the pivot axis along the slot. An elongated tine is adjustably and removably connected to each jaw member to permit selective pivotal movement about an axis which is parallel to both the longitudinal axes of the jaw member and associated tine.
