VIBRATION SMOOTHING MACHINE WITH WORKING TOOL FLEXIBLE SUSPENSION Russian patent published in 2012 - IPC B28B11/08 

FIELD: machine building.

SUBSTANCE: invention relates to construction machinery and is intended for displacement of vibration smoothing machines on not hardened surface of whatever reinforced concrete articles produced using bonding substances. Proposed machine comprises drive motor and working member, flexible suspension of the latter made up of a set of winches secured in pairs one above the other, regulator, transducers to control angular speed and torque of winch drums, as well as cable rope length, guide device and drive mounted in support frame and rigidly fixed on separate foundation. Said frames with winches are arranged opposite each other to make apices of rectangular site, while said working member in is arranged special frame fastened thereto by eight cables slipped from their winches. Thus, in coordinated operation of all winches, smoothing working member may move on all processed article along preset path under control of control unit connected with regulating units and transducers of all winches.

EFFECT: limiting undesirable alternating sign vibration load on machine assemblies.
