ABSTRACT:
Handling equipment and a grapple device for handling balled plant loads such as trees and shrubs are disclosed. The grapple device which may be pivotally mounted on any suitable vehicle has a lengthwise frame. A pair of pivot rotary actuators having their rotational axes oriented transversely to each other are attached to the end of the frame. A grapple mechanism having pair of diametrically opposed grapple blades pivotally attached to a support member is fastened to one of the pivot rotary actuators. The grapple blades are opened or closed about the root ball of a plant by means of actuators, preferably hydraulic cylinder actuators. The grapple mechanism also has a slidably adjustable foot member which is positioned between the grapple blades to stabilize the plant load. The interior surfaces of the grapple blades and foot are adapted to engage the root ball of the plant.
