Abstract: A lifting arm arrangement for lifting a pipe includes a pipe stacking tool comprising a first end, a second end, and a pipe handling head arranged at the second end. The pipe handling head is configured to grip around the pipe. A gripper head is connected to the first end of the pipe stacking tool. A tilt shaft is configured to connect the pipe stacking tool and the gripper head so as to form an articulated joint. The articulated joint comprises a locked position in which the pipe stacking tool is prevented from tilting about the tilt shaft, and a neutral position in which the pipe stacking tool is allowed to tilt about the tilt shaft.

Abstract: A device which moves a die between a retracted position, thereby releasing the die from the device, and an advanced position, thereby fixing the die to the device. The device includes an inner body comprising an inner body wall, and an inner body set of inclined faces. A body comprises a longitudinal groove. The longitudinal groove comprises an inner wall which contacts the inner body wall. An intermediate body comprises a first longitudinal side comprising a longitudinal side set of inclined faces, and a second longitudinal side arranged opposite thereto. The first longitudinal side cooperates with the inner wall. The second longitudinal side cooperates with a first side of the die. The longitudinal side set of inclined faces cooperates with the inner body set of inclined faces. A relative movement between the intermediate body and the inner body moves the die between the retracted position and the advanced position.

Abstract translation: 一种在缩回位置之间移动模具的装置，从而将模具从装置上释放，并且提前位置，从而将模具固定到装置上。 所述装置包括内体，所述内体包括内体壁，所述内体具有倾斜面。 主体包括纵向凹槽。 纵向槽包括接触内壁的内壁。 中间体包括第一纵向侧，其包括纵向侧面的一组倾斜面和与其相对设置的第二纵向侧。 第一纵向侧与内壁配合。 第二纵向侧与模具的第一侧配合。 倾斜面的纵向侧组与内主体倾斜面组合。 中间体和内体之间的相对运动使模具在缩回位置和前进位置之间移动。
