Abstract
A measurement device is furnished at a lifting means, in particular at a lifting rope, subjected to a load and used in hoisting machines. A support element (5) is disposed at the hoisting device and is attached with at least two force transducers (1) via in each case a support hinge (4). The free ends (3) of the force transducers (1) are joined to each other via a common hinge (9). The lifting means (10) engages at the hinge (9). The force transducers (1) are connected for transferring the force-proportional measurement signals to a signal processing means (12-15). This provides a measurement device and a measurement method which achieves reliable and relevant measurement values with high precision and accuracy. The measurement device is further capable of capturing and determining the forces present at lifting means, and in particular at lifting rope, including the gravity weight force of the load attached to the lifting means, and of the pendulum angle of the lifting means, as well as furnishing a measurement value transducer for a pendulum balancing control system.
