Problems solved by technology

[0006] However, in the case of large aircraft structural members, it is difficult for the operator to use the crane controls to set the target load force because the lifting fittings and / or the lifting fittings and / or are not properly visible from the crane operator's position or spring

Embodiment Construction

[0025] exist figure 1 , the proposed connection assembly 1 with the proposed dismounting aid 2 is shown. The removal aid supports the removal of the lifting attachment 3 from the workpiece 4 . The lifting attachment 3 is mounted to the workpiece 4 via one or more dowel bolts 3a.

[0026] The workpiece 4 may preferably be an aircraft structural component, such as, for example, a fuselage section and / or a wing section and / or a stringer of the aircraft.

[0027] In the aircraft industry, such workpieces 4 are typically moved within a plant by lifting equipment such as a plant master crane. The lifting device is designed to transport and move these large and heavy workpieces 4 respectively within the plant from one work station (preferably an assembly station) or storage station to another work station or storage station. This lifting device is also used to take workpieces 4 from the frame on which workpieces 4 can already be transported. In order to transport the workpiece 4 ...

Abstract

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 tothe 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 of the first connector (5) to the second connector (6) when an increasing force (F) is applied to the first connector (5) and the second connector (6).

Description

technical field [0001] The invention relates to a dismounting aid according to claim 1 for dismounting a lifting fitting from a workpiece, preferably from an aircraft structural component, a connection assembly according to claim 16 and a dismounting aid according to claim 18 from A method of disassembling a work piece, preferably a lifting fitting, from an aircraft structural member. Background technique [0002] In the state of the art, it is known to mount lifting accessories to aircraft structural components in order to remove or move the aircraft structural component from, for example, a supporting frame or onto, eg, a supporting frame. These lifting accessories are typically mounted to aircraft structural members via dowel bolts. Due to the relatively high weight of the lifting fitting, in order to remove the lifting fitting from the aircraft structural member by loosening the dowel bolts, the weight of the lifting fitting must be compensated by means of a lifting dev...
