A scissor lifting arrangement comprising: a foot for resting the lifting arrangement against a supporting surface; at least one leg having first and second longitudinal ends (3a, 3b), the leg being pivotally coupled to the foot at the first longitudinal end thereof; at least one arm having first and second longitudinal ends (4a, 4b), the first longitudinal end of the arm being pivotally coupled to the leg; a head for supporting a load to be lifted, the head being pivotally coupled to the second longitudinal end of the arm; a primary actuation mechanism, comprising a drive screw, a nut and a nut-carrier, by which a separation distance between the head and the foot is adjustable between an extended and a collapsed position; characterized in that, the nut is held by the nut-carrier at which, during rotation of the drive screw, it is arranged to be translated between a first end and a second end of a predetermined range; the drive screw and nut-carrier are respectively operatively coupled to an arm and a leg, so that rotation of the drive screw in a first direction, from a minimum separation distance, causes translation of the nut towards the first end of the predetermined range, where after, upon sustained rotation of the drive screw in the first direction, the arm and leg will be pulled towards respective more extended positions, which increases the separation distance; and subsequent rotation of the drive screw in a second direction, opposite to the first direction, decreases the separation distance, and sustained rotation of the drive screw in the second direction, causes translation of the nut towards the second end of the predetermined range at the minimum separation distance; a secondary actuation mechanism arranged to be effected by translation of the nut from the second end towards the first end of the predetermined range at the nut-carrier to cause at least one of the leg, the arm, the head and the foot to be pushed towards a more extended position, which increases the separation distance. a foot for resting the lifting arrangement against a supporting surface; at least one leg having first and second longitudinal ends (3a, 3b), the leg being pivotally coupled to the foot at the first longitudinal end thereof; at least one arm having first and second longitudinal ends (4a, 4b), the first longitudinal end of the arm being pivotally coupled to the leg; a head for supporting a load to be lifted, the head being pivotally coupled to the second longitudinal end of the arm; a primary actuation mechanism, comprising a drive screw, a nut and a nut-carrier, by which a separation distance between the head and the foot is adjustable between an extended and a collapsed position; characterized in that, the nut is held by the nut-carrier at which, during rotation of the drive screw, it is arranged to be translated between a first end and a second end of a predetermined range; the drive screw and nut-carrier are respectively operatively coupled to an arm and a leg, so that rotation of the drive screw in a first direction, from a minimum separation distance, causes translation of the nut towards the first end of the predetermined range, where after, upon sustained rotation of the drive screw in the first direction, the arm and leg will be pulled towards respective more extended positions, which increases the separation distance; and subsequent rotation of the drive screw in a second direction, opposite to the first direction, decreases the separation distance, and sustained rotation of the drive screw in the second direction, causes translation of the nut towards the second end of the predetermined range at the minimum separation distance; a secondary actuation mechanism arranged to be effected by translation of the nut from the second end towards the first end of the predetermined range at the nut-carrier to cause at least one of the leg, the arm, the head and the foot to be pushed towards a more extended position, which increases the separation distance.
