摘要： A power tool is provided for turning the screw collars (7) of falsework without the requirement of having to use spanners with long torque bars and without having to strike those torque bars with hammers or sledgehammers in order to exert the necessary torque on the collars (7). The tool is in two parts. A first part is a screw collar (7), or a collar adapter (10) which can be closed and locked around the screw collar (7) to be turned. The collar (7) or the collar adapter (10) has one or more drive engagement elements (11). The second part is a motor housing (20) supporting a motor (19) and a motor drive element (16) such as a spur gear. The motor housing (20) is formed to take its angular support from a falsework post (1) and its vertical support from either the falsework post (1), the screw collar (7) or the collar adapter (10). The motor (19) drives the motor drive element (16) such as the spur gear which engages the drive engagement element or elements (11) of the screw collar (7) or the collar adapter (10), drivingly to turn the screw collar (7) either directly or by rotation of the collar adapter (10).
