Gripper device for gripping a pipe

Abstract

A pipe gripping device includes a gripper arm arrangement having first and second gripper arms and having an open state which enables the pipe to be introduced into an opening between the arms, and an engaged state in which the gripper arms are adapted to engage with the pipe. First and second drive arms movably connect the respective first gripper arm and the second gripper arm to a support structure. Pivots rotationally connect the drive arms to the support structure. The device further comprises a transmission drive shaft and a transmission arrangement having first, second and third transmission members, each rotatable in respect to each other and coupled with each other. The first member is coupled with the drive shaft, the second member is coupled to the first member and the first drive arm, and the third member is coupled with the second member and the second drive arm.
