Abstract: Example methods, apparatus, system, and articles of manufacture for releasably locking components that are moveable relative to one another are disclosed herein. A disclosed example locking apparatus includes a locking device mountable to a first component and including at least one locking member. The example system also includes a catch member mountable to a second component. The catch member has a plurality of substantially similarly formed catches. The locking member is engageable with at least one catch in a plurality of predetermined catching positions in at least one of a releasable, form-locking manner or a releasable, force-locking manner. The example system also includes a force member to produce a relative movement between the locking member and the at least one catch. In at least a partial region of the catch member, at least a first catching position, a second catching position and a third catching position are traversable by the locking member.

Abstract: Embodiments of a scissor lifting platform comprising at least two crossing lower scissor bars, at least two crossing upper scissor bars articulatedly connected to the lower scissor bars, and a lower joint connecting the two lower scissor bars with each other and an upper joint connecting the two upper scissor bars with each other. Furthermore, the scissor lifting platform comprises at least one lifting aggregate connected to the lower scissor bar or the upper scissor bar and at least one rail having at least one contact area and being supported on the upper scissor bars. The upper scissor bar is articulatedly connected to the at least one rail and the other one of the upper scissor bars is guided by the at least one rail so as to be movable in a longitudinal direction when the scissor lifting platform moves.

Abstract: The subject matter of the invention relates to a support arm for a lifting platform, comprising at least one relatively wide support arm and an extension arm telescopically slidable therein, the arms each having torsionally rigid and flexurally stiff hollow profiles, a support bearing at the rear end of the accommodating arm for the pivotable hinging connection to a lifting carriage of a column and a bearing foot at the free end of the respective extension arm. A cost-effective production of support arms in different sizes and shapes is obtained by cutting at least the accommodating arm from a steel panel blank and forming it into a hollow profile and providing it with at least one transverse reinforcement.

Abstract: The invention relates to a scissors-type lifting platform, in particular for vehicles: including: stationary support rails on or in the floor level, at least two scissors arms which cross each other and are retained and guided with their bottom ends in the support rails, a hinge connecting the two scissors arms approximately centrally to each other, a lifting assembly engaging the scissors arms for spreading and contracting the scissors arms, at least one travel rail having contact areas and supported on the top ends of the scissors arms, wherein one of the scissors arms is connected to a travel rail with its top end in hinged manner and the other scissors arm is guided on the travel rail with its top end in longitudinally displaceable manner upon the lifting and lowering movement of the scissors-type lifting platform, characterized in that the longitudinally displaceable ends of the two scissors arms (12, 13; 20, 21) can be arrested with the associated travel rail (28) at least in the lifted position.

Abstract: The subject matter of the invention relates to a support arm for a lifting platform, comprising at least one relatively wide support arm (11) and an extension arm (12) telescopically slidable therein, the arms each having torsionally rigid and flexurally stiff hollow profiles, a support bearing (6) at the rear end of the accommodating arm (11) for the pivotable hinging connection to a lifting carriage (5) of a column (2) and a bearing foot (31a) at the free end of the respective extension arm (12). A cost-effective production of support arms in different sizes and shapes is obtained by cutting at least the accommodating arm (11) from a steel panel blank and forming it into a hollow profile and providing it with at least one transverse reinforcement (13).
