The Bobcat hydraulic clamp “kit” includes a grapple and hydraulic cylinder activated by the standard auxiliary hydraulics of the excavator. This attachment can be used with a standard trenching or digging bucket. The hydraulic clamp functions like a human thumb to handle odd-shaped objects. Broken concrete, tree stumps and stone blocks can be grasped, lifted and placed with great speed and accuracy. This tool is ideal for a wide range of jobs: for demolition, picking up and loading blocks of concrete or asphalt into a truck or trailer; for construction, handling large border stones; for landscaping, picking up and placing objects or removing debris; and for rental applications. When not needed, the clamp can be completely retracted onto the inside of the dipper stick and will not interfere with normal digging activities.
