An apparatus for applying force to a workpiece, the apparatus having a frame with spaced first and second side members and a top frame assembly. An anchor is spaced downwardly from the top frame assembly. There is a force generator connected to the frame assembly. The force generator is operative to apply a force to a workpiece connected between and to the force generator and anchor.

A person lift system includes a lift unit, a sling bar that is coupled to the lift unit, where the sling bar includes a plurality of attachment points each having coupling sensors and an electronic control unit that is communicatively coupled to the coupling sensors. The person lift system also includes a lifting accessory having a plurality of lifting points that are adapted to be selectively coupled to the plurality of attachment points of the sling bar. The electronic control unit comprises a processor and a computer readable and executable instruction set which, when executed by the processor detects with the coupling sensors whether the lifting accessory is installed in a proper manner and projects an indication when the lifting accessory is installed in the proper manner.

A safety load hook with a lower part defining a curved hook mouth with a hook opening of a predefined nominal width. An upper part is attached to the lower part and is pivotable into an open position for insertion or removal of a load, and into a closed position blocking insertion of a load or removal of a load. A marking is on each of the end regions of the upper part and lower part which face one another in the closed state. When closed, and when a size of the hook opening corresponds to the nominal width, the lower part marking is offset from the upper part marking. The offset distance is chosen such that when there is a predefined maximum widening of the hook mouth in relation to the predefined nominal width thereof, both markings are located directly side by side in the closed state.

The invention relates to a demounting aid (2) for demounting a hoisting fitting (3) from a workpiece (4), preferably from an aircraft structural component, comprising a first connector (5) and a second connector (6), a force measurement device (7) for measuring the force (F) applied between the first connector (5) and the second connector (6), a, preferably remote, display (8) for displaying an information corresponding to the respective force (F) applied between the first connector (5) and the second connector (6) and at least one elastic member (9) which allows a relative movement oft he first connector (5) to the second connector (6) when an increasing force (F) is applied tot he first connector (5) and the second connector (6).
