CRANEWAY BEAM ENDURANCE TEST STAND Russian patent published in 2002 - IPC

FIELD: mechanical engineering; testing facilities. SUBSTANCE: proposed test stand has foundation with rigidly secured frame, balance trucks hinge-secured on frame, installed with wheels upwards and orientated along two parallel axes, bridge crane model with balance wheels and horizontal coupler connected with crane model for fixing in longitudinal direction connected to frame of mechanism for longitudinal reciprocation with preset amplitude, one or two power hydraulic jacks for loading beams under testing located between frame of bridge crane model and frame of test stand, connecting rod and mechanism for longitudinal reciprocation at preset amplitude connected with connecting rod. Guide rails are secured on lower and upper belts of lower and upper units of beams to be tested by means of which lower unit of said beams on balance trucks and on which bridge crane model rests by balance wheels. Upper unit of beams to be tested is connected with lower unit of said beams by means of several joints, with connecting rod being connected with one of extreme joints. EFFECT: improved accuracy of results and enlarged functional capabilities. 4 dwg
