MULTIPURPOSE MODULAR HYDARULIC GRIPPER WITH SYNCHRONIC AND ASYNCHRONIC OPERATION

The present invention discloses a multi-purpose hydraulic gripper consisting of a hydraulic drive (1)， a rotator (2)， an adjustment plate (3) and a bearing (4)， where any pair of gripping arms (3A， 3B) is attached to the hydraulic drive (1). or (63A， 63B) or two hands (64) or (76A， 76B). In the housing (11) of the hydraulic drive there are two identical hydraulic cylinders (16A， 16B) and the control part of the hydraulic drive， which enables synchronous and asynchronous operation of the hydraulic drive (1). The hydraulic drive (1) is connected to a variable displacement hydraulic pump that is part of the working machine. Each gripping arm (3A， 3B， 63A， 63B， 64， 76A， 76B) has a pair of clamping lugs in the upper part， and the gripping of the gripping arms (3 A， 3B， 63 A， 63B， 64， 76A， 76B) on the hydraulic drive is performed by means of clamping levers (19A， 19B). The invention also discloses gripping arms (76A， 76B)， with a knife (780A， 780B) with a curved blade that allows cutting trees. Said hydraulic drive can be made in different sizes， where the size of the hydraulic drive is determined by the distance (A) between the axes of the shafts (17B) of the shaft (17).
