Mining machines damaging vibrations

Jan 03, 2017 Jan 03, 2017 Exposure to whole-body vibration (WBV) negatively impacts the health and safety of exposed mine workers. Off-road mining equipment operates on rough surfaces under harsh operating conditions that produce WBV and mechanical shock. Vibration is often complex, contains many frequencies, occurs in several directions, and changes over time
