A material-handling device is disclosed, particularly for use as grappling apparatus for the loading and unloading of balled trees and shrubs in the nursery industry. By providing hydraulically powered rotational means in the vertical plane coupled to and in front of hydraulically powered rotational means in the horizontal plane, an arrangement is provided which is capable of rotating a load by a full 190.degree. about a vertical axis and tilting the load vertically in a range of about 100.degree., while developing greater lifting power and economic advantages over similar apparatus employing pivot rotary actuators.
