FIELD: metallurgical, mechanical engineering and other industries; weighing of loads handled by lifting and transportation mechanisms. SUBSTANCE: balance has housing with cover connected by cable with crane lifting drive. Placed in housing are force measuring transducer, force input unit, supply unit and weight visual indicator. Force input unit is made in form of two resilient members of different rigidly connected in tandem through plate in center of which load lifting hook is hinge mounted. Higher rigidity resilient member is arranged between base of housing and plate, and lower rigidity resilient member, between plate and base of force measuring transducer whose power input is coupled with housing cover through pressure screw. EFFECT: improved reliability at shocks and enlarged operating capabilities. |
