Patent

CA 2641321

A grappler for use in grasping and manipulating pipe segments for large diameter pipeline tie-ins has a first frame and a second frame movably secured thereto. A pair of grapple arms is pivotally mounted to each frame and is actuated between a open position and a closed position to engage and grasp the pipe segments. An actuator displaces the second frame relative to the first frame in a first degree of movement to displace one pair of grapple arms relative to the other pair of arms, and a support frame provides the grappler with two additional degrees of movement. When mounted to a backhoe or like device, the grappler facilitates safe retrieval of pipe from hazardous trenches, and provides handling and alignment of the pipe segments for easier and safer welding of the pipe joints.
