Abstract. "The deployment of large machinery for low cost bulk surface mine production operations has resulted in high-impact shovel loading operations (HISLO). In extreme cases shovels load large dump trucks with 100-ton (or more) passes generating forces under gravity. HISLO generates high-frequency shockwaves that cause severe exposing operators to whole body
Technological advances have resulted in large shovels and trucks for bulk economic operations causing high-impact shovel loading operations (HISLO). The resulting HISLO impact forces cause significant vibrations which are transmitted through the truck frame into an operator's cabin.
Sep 01 2011 · High-impact shovel loading operations (HISLO) can involve severe truck vibrations that expose operators to whole body vibration (WBV). The operators lower torso lower back legs feet and hands are exposed to these levels. The operator seat lumbar and cervical regions are severely impacted by high levels.
