Abstract

A grapple suitable for standing-stem log harvesting includes a vertical elongate backplate located between a pair of horizontally extending gripping jaws pivotally mounted relative to the backplate for gripping and releasing the trunk of a tree.
The grapple hangs in vertical operating position when suspended, and may include a plurality of vertically spaced and mutually vertically offset fingers associated with the jaws to distribute the gripping force.
