System för vägning av laster i en lyftnings- och förflyttningsanordning

摘要

A weighing system for determining the weight of a load that is manipu­lated by means of a lifting and transfer apparatus that comprises an ar­ticulated boom moving on the vertical plane (X-Z) and a tip piece (11) attached thereto, which is intended for the suspension of the load. The system comprises sensor means (23) fastened to said tip piece (11) whose output consists of one or several output signals (23b) pro­portional to the loading caused by the load, and calculation means (23c, 23d) that are arranged to measure the weight of the load cor­responding to said output signals. The system comprises a separate tip piece to be attached to a lifting and transfer apparatus for suspension of loads, said tip piece comprising a first end (11 d) intended for at­tachment, and a second end (11 c) comprising means for suspension of the load (12, 13). The central part of the tip piece (11) is provided with a location for a measurement device (23) that is intended especially for measurement of deformations and that comprises means (25, 26) for fastening of said measurement device, wherein said deformations are proportional to the loading caused by the weight of the load.
