VIBRATORY EQUIPMENT

VIBRATORY EQUIPMENT, a combination of methods and means (crank­type, piston­type, electromagnetic and centrifugal drives) of vibration excitation, measurement (vibration meters, vibrographs, etc.) and control. Vibration machines for well drilling, portable pneumatic vibratory concrete breakers, strikers, hammers, etc. were manufactured in Bashkortostan in 1987–2014, by STIN­M Enterprise. In the late 1990s the USATU developed vibro­ percussion tools (ice breakers, motor vibratory strikers, pipe driving machines, etc.) based on the design of free­piston internal combustion engines. In 2000–06 they were produced by EcoMotor Research and Development Centre (Ufa). BashStroy (Ufa) and Stroymash (Sterlitamak) are piledriver equipment producers.
