A tubular product clamp for clamping a tubular product e.g. a drilling pipe, the product clamp having a ring frame having three or more clamping devices, which clamping devices are provided at regular intervals along the inside of the ring frame around a central product passage having an axis, characterized in that each clamping device comprises: - a base part, which base part is mounted to the ring frame, and has a front side 16 that defines a guide surface facing towards the central product passage, and a left side and a right side provided with cam tracks, the cam tracks extending substantially parallel to the guide surface defined by the front side; - a clamp part, which clamp part has a back side that defines a guide surface facing the guide surface defined by the front side of the base part, a front side facing the central product passage, and a left side and a right side provided with cam tracks (20, 27), the cam tracks (20, 27) extending substantially parallel to the guide surface defined by the back side; - two load transfer rollers (10, 11), which load transfer rollers (10, 11) are each provided between the guide surface of the base part and the guide surface of the clamp part to provide a rolling support for the clamp part; and - a trolley frame, which trolley frame is configured for positioning the base part, the clamp part and the load transfer rollers (10, 11) relative to each other, which trolley frame carries the load transfer rollers (10, 11), which load transfer rollers (10, 11) are each rotatably mounted, wherein the trolley frame is provided with cam followers, with which cam followers the trolley frame engages the cam tracks (20, 27) in the sides of the base part and the clamp part; and wherein the guide surface of the base part and the guide surface of the clamp part define between them guide tracks for each of the load transfer rollers (10, 11), which guide tracks extend at an angle with the axis of the central product passage such that by moving the clamp part relative to the base part, the clamp part is moved along the axis as well as in radial direction thereof. - a base part, which base part is mounted to the ring frame, and has a front side 16 that defines a guide surface facing towards the central product passage, and a left side and a right side provided with cam tracks, the cam tracks extending substantially parallel to the guide surface defined by the front side; - a clamp part, which clamp part has a back side that defines a guide surface facing the guide surface defined by the front side of the base part, a front side facing the central product passage, and a left side and a right side provided with cam tracks (20, 27), the cam tracks (20, 27) extending substantially parallel to the guide surface defined by the back side; - two load transfer rollers (10, 11), which load transfer rollers (10, 11) are each provided between the guide surface of the base part and the guide surface of the clamp part to provide a rolling support for the clamp part; and - a trolley frame, which trolley frame is configured for positioning the base part, the clamp part and the load transfer rollers (10, 11) relative to each other, which trolley frame carries the load transfer rollers (10, 11), which load transfer rollers (10, 11) are each rotatably mounted,
