Abstract
The invention relates to a tubular product clamp for clamping a tubular product, such as a drilling pipe, and to thus support for example a string of drilling pipes. The product clamp has a ring frame and three or more clamping devices mounted along the inside of that ring frame and around a central product passage. According to the invention each clamping device comprises a base part and a clamp part and two load transfer rollers carried by a trolley frame. The trolley frame positions the base part, the clamp part and the load transfer rollers relative to each other. The base part and clamp part define between them a track, along which the load transfer rollers roll when the clamp part is moved relative to the base part.
