Crane load indicating arrangement |
摘要 |
A crane load indicator in which actual loading is determined by a strain transducer as a function of shear stress on a crane boom. A resultant actual loading signal is compared with a computed signal representative of the maximum crane loading for the prevailing conditions and the two signals are compared to provide an indication of available lifting capacity.
