Driver Seat Improvement in Deep Mine Tipper for Sustained Driving Comfort

Drivers of tipper vehicles due to the nature of the application of carrying heavy loads as well as the rough terrain in off-road conditions are either continuously or intermittently exposed to comprehensive magnitudes of low frequency high amplitude whole-body vibration.

This being attenuated due to the nature of the primary vehicle suspension, which is designed to take higher tonnages of load carrying capacity as well as to withstand the rigors of the off road terrain conditions.

Prolonged occupational exposure to such vibration has been associated with disorders of the lumbar spine and the connected nervous system. This paper deals with the selection of driver seat suspension to reduce and dampen the transmission of potentially injurious vibration and shock motions to the seated drivers.
