Hydraulic grapple clamp

A hydraulic grapple clamp to be lifted by a host machine, comprising:

• an L-shaped frame having a crossbeam, said crossbeam having a first and second end and a front and rear, and a lower leg extending at a right angle from the second end of said crossbeam at the junction thereof, said crossbeam having defined thereon attachment means to be affixed to said host machine, said lower leg having a base with mounting means thereon;
• an adjustable clamp member adjustably mounted to the mounting means at the base of said lower leg;
• a movable arm having a top, a central portion and a bottom;
• means to rotatably attach the top of said movable arm to the first end of said crossbeam of said frame;
• an upwardly and downwardly movable clamp member disposed at the bottom of said movable arm, said movable clamp member facing said adjustable clamp member;
• a hinge base disposed at the junction of said crossbeam and said lower leg, said hinge base extending around from the front to the rear of said lower leg, said hinge base disposed at an angle of approximately 11 degrees to said crossbeam;
• a hydraulic ram having a first and second end and a piston therein, the first end of said hydraulic ram being pivotally attached to said movable arm;
• the second end of said hydraulic ram affixed to said hinge base;
• and
• a strong back welded integrally to and extending along a portion of the rear of said crossbeam interconnected to the portion of said hinge base extending around from the front of said L-shaped frame, said device operable by hydraulic action with a first hydraulic line extending to one side of a piston within said hydraulic ram and a second hydraulic line extending to the other side of said piston, each hydraulic line disposed on an opposite side of said piston within said ram such that said movable arm can be moved back and forth by the operation of said hydraulic ram.
