Timber grabber, as the name suggests, is a wood grabbing machine, which is generally evolved from a hydraulic excavator. The difference between a log grabber and an ordinary excavator lies in the front end working device, that is, the work purpose is different: the large and small arms of the ordinary excavator are generally shorter, and the front end is a bucket, whose main function is to carry out excavation and loading operations; The large and small arms are commonly known as "grabbing arms". They are generally longer and different in shape and structure from ordinary excavators. The front end is a wood grabbing machine. Its main function is to load and unload wood, timber, reeds, straw and various strip materials. And handling operations. The original log grabber means that the new machine is a complete log grabber when it leaves the factory. That is to say, the machine manufacturer designs and produces according to the requirements and standards of the log grabber from the beginning until it leaves the factory. Original wood grabbers are generally more expensive. Modified log grabbers, as the name suggests, are modified log grabbers, which are generally converted from ordinary excavators used for excavation purposes.
