Abstract: A linear actuator comprising a cabinet (1), an electric motor (2), a transmission (4), a gear housing (11), a spindle nut (6), a spindle (5), the actuator being furnished with an opening (20) in the gear housing (11), where a gear wheel power take-off (21) is accessible and may be equipped with optional equipment. The gear wheel power take-off (21) is constructed as a tooth gearing on a planetary wheel holder (16) in a planetary wheel and transfers a movement to the optional equipment, which is proportional to the movement of the spindle nut during its travel on the spindle.

Abstract: Linear actuator (1) comprising an electric motor connected to a spindle via a transmission, on said spindle is mounted a spindle nut secured to an activation element (2), said activation element (2) being equipped with a front attachment (3). The actuator (1) is further furnished with a rear attachment (4), which is axially displaceable between defined stops. The rear attachment (4) activates a switch (7) in at least one of the displaceable positions of the rear attachment (4).

Abstract: A linear actuator comprising a spindle (5) with a spindle nut (6), where the spindle (5) is driven by an electric motor (2) via a transmission (3,4), comprising a planetary gear (4). The construction is constructed in such a way that the spindle (5) is lead through the transmission (3,4) and is embedded by means of a ball bearing (20) in connection with a rear mounting (10), causing the axial forces to be lead through the transmission (3,4) via the spindle (5) and the ball bearing (20) to the rear mounting (10). This means that the construction is simpler and less voluminous and that the axial forces, moreover, are not transferred to the transmission.

Abstract: An emergency lowering (retraction) mechanism for a linear actuator includes first and second cylindrical parts, an operating handle outside of the first cylindrical part, and a coil spring which has a first end connected to the operating handle, a second end connected to the second cylindrical part, and a plurality of windings, with some of the windings wrapping around and contacting the outer periphery of the first cylindrical part and some wrapping around and contacting the outer periphery of the second cylindrical part.

Abstract: An actuator system comprising a housing (2, 19) having at least one socket (6) for the insertion of an electrical plug (7). The housing (2, 19) is provided with an arrangement which is capable of retaining an electrical plug, preferably of the Jack, DIN or Minifit type, inserted into said socket, said arrangement comprising a union nut (8) which may be retained in a position above the opening of the socket (6), and which at the same time surrounds the plug (7), said union nut (8) being rotatable between an inoperative position in which the plug (7) may freely be inserted and removed, and another position which is a locked position, in which the plug (7) cannot be inserted and, if it is already inserted, cannot be removed.

Abstract: Actuator comprising a reversible electric motor (7) which through a transmission (8) rotates a spindle (9), and where there on the spindle is a spindle nut (10), whereto an activation rod (11) is connected, and where there on a front end of the activation rod is secured a front mounting (16). Between the activation rod and the front mounting there is an emergency lowering mechanism (14).
