Abstract

A unidirectionally torque- applying wrench includes a holder 12 which may be in the form of a ring spanner or an open-ended spanner. A lever 13 is pivoted to the holder and when moved in one direction engages an object to be turned either directly or via a slide 18. The object is released when the lever is moved in the opposite direction. The holder 12 and the lever 13 with or without the slide 18 may be used as a hand tool or a drive unit 27,28 may be used to apply torque to the object and the drive unit may be hydraulically operable. A reaction lever 15 is pivoted to the holder 12 or to the lever 13 radially inward of the pivot 14 between the lever and the holder. The space between the drive unit and the reaction lever 15 is taken up by elastomeric material for safety. <IMAGE>
