ASSEMBLED WEIGHT Russian patent published in 1999 - IPC

FIELD: hoisting gears, static and dynamic testing. SUBSTANCE: assembled weight includes set of marked plates. Units joining weights have centering bushings and bolted joints are guarded against fall-out and are permanent. Upper weight is made in the form of tray for placement of additional correction weights. While conducting tests of hoisting mechanism suspension is formed out of weights and tray, closest in weight to computed mass, and correction weights which make it possible to conduct tests with little change of mass of tested weight. Invention provides for testing of hoisting gears of various load-carrying capacity in entire range of weight characteristics. EFFECT: improved testing of hoisting gears of various load-carrying capacity. 5 dwg
