摘要： The purpose of the present invention is to provide a safe device with which, by forcibly braking the rotation of a grapple by means of an external force, it is possible even for an unskilled operator to bring the rotation to a halt and further to prevent accidents due to such rotation. Another purpose of the present invention is to provide such a device at lower cost. According to the present invention, a grapple has a lower frame that has claws for gripping timber and an upper frame that rotatably holds the lower frame, and is provided with a rotation braking means that applies a brake on the rotation of the lower frame.
