CANADA- LUMBERMAN a Link-Belt Company's Improved Wood Grapple The wood grapple is without question the most effective and economical tool yet devised for unloading, piling and reclaiming evenly piled pulpwood and logs. It is usually handled and operated by a locomotive crane or double drum hoisting outfit, and is adapted for wood upward of four feet in length. Earlier forms of grapples were crude and comparatively unreli- able in service. With the demands of recent times for increased pro- duction and greater capacity, however, has come the development of grapples which are capable of a large volume of work, often under severe conditions. Ever since the first Link-belt grapple was built in Chicago, more than ten years ago, it has been the company's desire and aim to improve and perfect its design and construction. The first grapples had cast steel arms and coil closing chains acting in combination with wide face closing drum. This construction was improved by a more scientific design of grapple arms and closing drum by equaliz- ing the coil closing chains through the head yoke and in the drum guard. Still later the use of the flat link closing chain were found to be a decided improvement over the coil chains formerly used, both in strength and length of life. In the latest design of the Link-Belt grapple, known as the "Improved Type," are incorporated all of the features and details which careful study and long experience have proved to be advan- tageous and desirable. The accompanying cut illustrates the sub-. The latest type of wood grapple stantially reinforced, built-up, heavy section forged structural steel grapple arms, which give maximum strength and resistance against breakage and distortion when handling frozen logs. Logs and pulp- wood, regardless of length, have a tendency to roll or slide into the grapple
