Abstract
A modular structure for an energy wood grapple has at least two opposite jaws (31, 32) that are configured to press vertical trees against a blade, thereby cutting the tree. The remaining portion is held by the jaws (31, 32) against a body (10) of the energy wood grapple. The modular structure comprises two frame plates at opposite sides of the body (10), attached detachably, for example by bolts (23). The jaws (31, 32) are attached between the opposite frame plates detachably, to axles that provide a pivot for the jaws (31, 32).
Claims14
An energy wood grapple, comprising:
- a body;
- a first jaw pivotally connected to a third side of the body by a first axle;
- a second jaw pivotally connected to a fourth side of the body by a second axle;
- and
- means for cutting energy wood;
- wherein the first jaw and the second jaw are configured to reciprocate between an open position and a closed position and in the closed position push the energy wood against the body;
- a first frame plate is detachably connected to a first side of the body, transversely to the first axle and the second axle;
- a second frame plate is detachably connected to a second side of the body, opposite to the first frame plate;
- the first jaw and the second jaw are connected to the body via the first frame plate and the second frame plate, wherein
- the first axle is connected to the first frame plate and to the second frame plate;
- the second axle is connected to the first frame plate and to the second frame plate.
