Abstract: A support trolley for supporting a door of an aircraft to permit working on the door comprises a frame with an upper support portion having at least two pairs of support bolts for engagement with locking bolts of the door to be supported so that the door is supported at each lateral side by a pair of support bolts. For engagement with the locking bolts the support bolts comprise recesses at their free ends.

Abstract: A tool to screw/unscrew a screwing element, having a module comprising a lever extending radially from and rotatable around a drive axis, a first transmission element rotatable around the drive axis by the lever, a transmission module comprising a second transmission element cooperating with the first element, a third transmission element rotatable around a screwing/unscrewing axis parallel to, and spaced from, the drive axis, a transmission system comprising an element transmitting the second element rotation to the third element, and an adapter with a fourth transmission element cooperating with the third element, and a cavity confirming to the screwing element. The tool includes a wedge with at least one rotatable adapter mounted thereon. The wedge comprises two support surfaces on planes parallel to the drive axis and disposed opposite one another to define a groove receiving an end of the transmission module on the third element side.
