Abstract

The invention relates to a jack for aircraft, having a lifting cylinder (2) which is held rigidly in a framework (3) which has at least three stand supports (4, 5, 6) which are constructed as supporting wheels, the jack (1) having at least one inclination sensor for detecting deviations of its lifting cylinder from the vertical orientation, and the length of at least two of the supports (4, 5, 6) being variable, separately from one another, for vertical alignment of the lifting cylinder (2). In order to permit precise positioning and alignment of the lifting cylinder (2) underneath the lifting point (which is provided on the underneath of the aircraft) with a labour cost and time penalty which are as low as possible, the jack (1) has at least one electrical inclination sensor which is connected to an inclination display (10), the inclination display (10) having at least two optical display elements for at least two connecting shafts which are arranged between the lifting cylinder (2) and the associated support (4, 5, 6), of which display elements the one displays an extension which the lifting cylinder is required to make for vertical alignment and the other displays a corresponding shortening of the support (4, 5, 6) associated with the connecting shaft. In this case, it is proposed according to a developed proposal in accordance with the invention that the hydraulic cylinders (4, 5) be connected by at least two of the variable-length stand supports (4, 5, 6) to a control device (14) and to at least one hydraulic pump, and that an electrical control connection for vertical alignment of the lifting cylinder (2) be provided between the control device (14) and at least one electrical inclination sensor of the three-legged jack (1). <IMAGE>
