Abstract
This invention refers to hoisting equipment, in particular to position indicator for crane trolley with the extended boom. Technical result is to increase the measurement accuracy of the position indication for the crane trolley and reliability of the crane operation. Position indicator for the boom crane trolley com-prises synchron transmitter 9 kinematically connec- ted by its shaft with the mechanism of displacement of the crane trolley 6 mounted on the crane boom 2 and connected electrically with the synchro receiver 10 provided on the crane, boom with the scale 12 of the position of the crane trolley. Besides it is provided with the limit switch I mounted on the section of the boom from its fastened end with the shifting in respect of it and with the possibility of co-operation with the synchro transmitter having electromagneting clutch 3 electrically connected with said limit switch. fig. 1.
