ABSTRACT:
An apparatus for gripping a pipe comprises an outer member having at least one inclined inner surface and an inner member having an inclined outer surface, a tubular member having an opening to accommodate said inner member and a threaded part, and a threaded gear engaged with the threaded part of the tubular member. On rotation of the threaded gear the tubular member moves the inner member which co-operates with the outer member so that said inner member moves towards a pipe to be gripped. The apparatus is particularly useful for applying "non-marking" jaws to the outside of tubulars in the oil and gas industry.
